Before explaining the embodiments of the present invention in detail, some related arts related to the embodiments of the present invention will be described.
With the continuous increase of intelligent terminal users, the user traffic and data throughput are continuously increased, higher requirements are put on the communication rate, and in order to meet the requirements of larger downlink and uplink peak rates, a mobile network needs to provide larger transmission bandwidth. For this reason, the fourth generation mobile communication technology (4G) network and the fifth generation mobile communication technology (5G) network introduce solutions of Carrier Aggregation (CA). Carrier aggregation may aggregate two or more carrier units (CCs) together to support a larger transmission bandwidth.
In an intra-station carrier aggregation scenario, one cell in a network device is configured as a primary cell of a terminal device, and other cells under the network device are configured as secondary cells of the terminal device. A primary cell (Pcell) is a cell established when a terminal device initially connects, or a cell performing Radio Resource Control (RRC) connection reestablishment, or a primary cell designated in a handover (handover) process. The primary cell is responsible for RRC communication with the terminal device. The carrier corresponding to the primary cell is referred to as a Primary Component Carrier (PCC). The downlink carrier of the primary cell is referred to as a downlink primary carrier (DL PCC), and the uplink carrier of the primary cell is referred to as an uplink primary carrier (UL PCC). A secondary cell (Scell) is added at RRC reconfiguration to provide additional radio resources. The carrier corresponding to the secondary cell is called a Secondary Component Carrier (SCC). The downlink carrier of the secondary cell is referred to as a downlink secondary carrier (DL SCC), and the uplink carrier of the secondary cell is referred to as an uplink secondary carrier (UL SCC).
In an inter-station carrier aggregation scenario, one cell in the main network device is configured as a main cell of the terminal device, and one cell under the auxiliary network device is configured as an auxiliary cell of the terminal device. The primary cell is a cell established when the terminal device is initially connected, or a cell for performing RRC connection reestablishment, or a primary cell designated in a handover (handover) process. The primary cell is responsible for RRC communication with the terminal device. The carrier corresponding to the primary cell is called a primary carrier. The downlink carrier of the primary cell is referred to as a downlink primary carrier (DL PCC), and the uplink carrier of the primary cell is referred to as an uplink primary carrier (UL PCC). The secondary cell is added at RRC reconfiguration to provide additional radio resources. The carrier corresponding to the secondary cell is called a secondary carrier. The downlink carrier of the secondary cell is referred to as a downlink secondary carrier (DL SCC), and the uplink carrier of the secondary cell is referred to as an uplink secondary carrier (UL SCC).
The relationship between a cell (cell) and a carrier (carrier) is: the cell has no physical entity, and is a logical concept, which is the smallest logical unit in the mobile communication network to provide a complete set of services (calling, called, mobile, internet-enabled, etc.) for users. The carrier wave is a radio signal (electromagnetic wave) with a specific frequency, bandwidth and system, which is transmitted by a network device, and is a main body for carrying information, and a cell may correspond to one or more downlink carrier waves and/or one or more uplink carrier waves. For example, a cell may correspond to a downlink carrier, an uplink carrier, and an Supplemental Uplink (SUL) carrier, where the SUL carrier refers to transmission in which only uplink resources are used for the current communication system.
In both the intra-station carrier aggregation scenario and the inter-station carrier aggregation scenario, before the auxiliary carrier is activated, the terminal device needs to complete channel quality measurement on the auxiliary carrier, that is, after the network device corresponding to the auxiliary carrier receives a channel quality report sent by the terminal device, the terminal device can perform data transmission on the auxiliary carrier (that is, the auxiliary carrier is activated). The time consumption of the channel quality measurement process is long, so that the activation time delay of the auxiliary carrier is long, and the wireless resource of the auxiliary carrier cannot be utilized for data transmission in time when the service volume of the terminal equipment is large, so that the resource utilization rate of the auxiliary carrier and the performance benefit of carrier aggregation are limited, and the service performance of the terminal equipment is influenced.
According to the technical scheme provided by the embodiment of the invention, the target terminal equipment takes the channel quality parameter of the target auxiliary carrier in the first time period as the current channel quality parameter of the target terminal equipment by indicating the two network equipment, so that the channel quality measurement process of the terminal equipment before the auxiliary carrier is activated in the related technology is omitted, the auxiliary carrier activation time is further shortened, and the quick activation of the auxiliary carrier is realized.
The technical scheme provided by the embodiment of the invention can be applied to various communication systems, such as a 5G system, a future evolution system or a plurality of communication fusion systems and the like. The technical scheme provided by the embodiment of the invention can be applied to various application scenes, such as machine-to-machine, macro-micro communication, enhanced mobile internet, ultra-high reliable ultra-low time delay communication, massive internet of things communication and the like. These scenarios may include, but are not limited to: communication scenarios between communication devices, network devices, and communication scenarios between network devices and communication devices, etc. The following description is given by way of example in a communication scenario between a network device and a terminal device.
In addition, the communication system and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not constitute a limitation to the technical solution provided in the embodiment of the present invention, and it can be known by a person of ordinary skill in the art that, along with the evolution of the communication system and the occurrence of a new service scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.
As shown in fig. 1, a schematic structural diagram of a communication system applicable to the embodiment of the present invention includes a first network device, a second network device, and a target terminal device, where the first network device configures a target primary carrier, the second network device configures a target secondary carrier, and the first network device communicates with the target terminal device through the target primary carrier. The target terminal equipment is any terminal equipment supporting the carrier aggregation function in the communication system; the target auxiliary carrier is any auxiliary carrier configured for the target terminal equipment in the communication system; the target main carrier is a main carrier accessed by target terminal equipment in the communication system.
In different application scenarios, the first network device and the second network device may be located in the same base station, or may be located in two different base stations, which is not specifically limited in this embodiment of the present invention. Illustratively, as shown in fig. 2, a first network device is located in the base station 1, and a second network device is located in the base station 2, at this time, the base station 1 configures a target primary carrier, and the base station 2 configures a target secondary carrier.
When the first network device and the second network device are located in the same base station, the data transmission mode between the first network device and the second network device is the data transmission between the internal modules of the devices. In this case, the data transmission flow between the two is the same as the data transmission flow between the first network device and the second network device in the case where the two network devices are located in two different base stations.
In the following embodiments provided in the embodiments of the present invention, a case where a first network device and a second network device are located in two different base stations is taken as an example for description.
Fig. 3 is a flow diagram illustrating a method of communication, according to some example embodiments. As shown in fig. 3, the communication method provided by the embodiment of the present invention includes the following steps S201 to S204.
S201, the target terminal device determines the first path loss of the target auxiliary carrier in the first time period at the target moment.
The target time is the time when the first network equipment indicates to activate the target auxiliary carrier of the target terminal equipment; the first time interval is a time interval before the target time when the latest target terminal equipment is in the target auxiliary carrier activation state.
As a possible implementation manner, when receiving a target secondary carrier activation indication message sent by a first network device at a target time, a target terminal device obtains at least one first path loss parameter of a target secondary carrier within a first time period, further calculates an average value of the at least one first path loss parameter, and determines the average value as a first path loss.
It should be noted that the path loss parameter is used to reflect a transmission path loss value experienced by an air interface signal when data is transmitted between the target terminal device and the first network device through the target secondary carrier, and is measured and calculated by the target terminal device. Specifically, the path loss parameter is defined as a difference between a target secondary carrier reference signal transmission power value and a target secondary carrier reference signal received strength value measured by the target terminal device; and the reference signal transmitting power value of the target auxiliary carrier is a preset fixed power value.
The reference signal may be a Cell Reference Signal (CRS) of a 4G cell, a channel state information reference signal (CSI-RS) of a 5G cell, a Positioning Reference Signal (PRS), a Tracking Reference Signal (TRS), or other newly defined reference signals, and the specific reference signal is not limited in the embodiments of the present invention. The position information and the preset power value of the reference signal in the time domain and the frequency domain can be sent to the target terminal equipment by the base station where the target auxiliary carrier is located through system broadcast messages or RRC messages.
In practical application, after the target secondary carrier is configured for the first time, the target terminal device measures the path loss parameter of the target secondary carrier according to a preset period. The preset period is a reference signal transmission period of the target secondary carrier. For example, the preset period is 10ms. The larger the preset period value is, the more power is saved for the target terminal equipment, but the lower the time precision of the path loss parameter measurement is.
It should be noted that, because the target secondary carrier is simultaneously accessed to multiple terminal devices, in order to meet the data transmission requirement of each terminal device, the first network device needs to transmit the reference signal according to a preset period no matter whether each terminal device is in the target secondary carrier activation state.
In some embodiments, the target terminal device may always measure the path loss parameter according to a preset period, or may start to measure the path loss parameter after receiving the target auxiliary carrier deactivation indication message, and stop measuring the path loss parameter after receiving the target auxiliary carrier activation indication message, so as to reduce the measurement frequency of the target terminal device and the power consumption of the terminal.
It should be noted that the first time period is located in a latest target secondary carrier activation time period before the target time, that is, the target terminal device is in a target secondary carrier activation state in the first time period. The specific length of the first time interval may be set in advance in the target terminal device by operation and maintenance personnel, or may be determined by the target terminal device according to a preset period, for example, the first time interval is an integral multiple of the preset period.
Optionally, the starting time of the first time period is located in the latest target secondary carrier activation time period before the target time, and the ending time is the ending time of the activation time period. For example, assuming that the first period length is 1 hour, and the last target secondary carrier activation period before the target time is 1 month 1 day 10.
S202, the target terminal device determines the second path loss of the target auxiliary carrier in the second time period.
And the second moment is a period of time when the latest target terminal equipment is in the target auxiliary carrier deactivation state before the target moment.
As a possible implementation manner, when receiving a target auxiliary carrier activation indication message sent by a first network device at a target time, a target terminal device obtains at least one second path loss parameter of a target auxiliary carrier in a second time period, further calculates an average value of the at least one second path loss parameter, and determines the average value as a second path loss.
It should be noted that the second time period is located in the most recent target secondary carrier deactivation time period before the target time, that is, the target terminal device is in the target secondary carrier deactivation state in the second time period. The specific length of the second time period may be set in advance in the target terminal device by operation and maintenance personnel, or may be determined by the target terminal device according to a preset period, for example, the second time period is an integral multiple of the preset period.
Optionally, the starting time of the second time period is located in the most recent target secondary carrier deactivation time period before the target time, and the ending time is the target time. For example, the first period is 1 hour, the last target secondary carrier deactivation period before the target time is 1 month, 1 day 23 to 1 month, 2 days 9, 00, and the second period may be 1 month, 2 days 8-00.
It should be noted that the length of the first time period may be the same as or different from the length of the second time period, and this is not limited in the embodiment of the present invention.
S203, the target terminal device determines a target path loss difference according to the first path loss and the second path loss.
As a possible implementation manner, the target terminal device calculates a difference value between the first path loss and the second path loss, and determines the difference value as a target path loss difference.
As another possible implementation manner, the target terminal device calculates a difference value between the first path loss and the second path loss, and determines a sum of the difference value and a preset error value as a target path loss difference.
It should be noted that the preset error value is preset in the target terminal device by the operation and maintenance staff.
It can be understood that, after receiving the target secondary carrier activation indication message, the target terminal starts to determine the target path loss difference. The target path loss difference reflects the path loss parameter change situation measured by the target terminal device in the latest target auxiliary carrier activation time period and the deactivation time period before the target time, and further reflects the wireless channel environment change situation between the target terminal device and the target auxiliary carrier in the two time periods.
And S204, under the condition that the target path loss difference is smaller than or equal to a first preset threshold value and the time interval between the first time interval and the second time interval is smaller than or equal to a second preset threshold value, the target terminal equipment sends a quick activation request message to the second network equipment.
The quick activation request message comprises an identifier of target terminal equipment and an identifier of a target auxiliary carrier; the quick activation request message is used for instructing the first network equipment to send a quick activation instruction message to the second network equipment; the quick activation indication message is used for indicating the second network equipment to activate the target auxiliary carrier of the target terminal equipment according to the channel quality parameter of the target auxiliary carrier of the target terminal equipment in the first time period; and the second network equipment configures the target secondary carrier.
As a possible implementation manner, the target terminal device compares the target path loss difference with a first preset threshold, and determines whether the target path loss difference is less than or equal to the first preset threshold. And the target terminal equipment calculates the time interval between the first time interval and the second time interval, compares the time interval with a second preset threshold value and judges whether the time interval is less than or equal to the second preset threshold value. And under the condition that the target path loss difference is smaller than or equal to a first preset threshold value and the time interval between the first time interval and the second time interval is smaller than or equal to a second preset threshold value, the target terminal equipment sends a quick activation request message to the second network equipment.
The first preset threshold and the second preset threshold are both set in the target terminal device by operation and maintenance personnel in advance.
It should be noted that the target terminal device may send the fast activation indication message to the second network device through the first network device (that is, the target terminal device sends the fast activation request message to the first network device first, and accordingly, the first network device forwards the fast activation indication message to the second network device).
It can be understood that the target path loss difference reflects a change situation of a wireless channel environment of the target secondary carrier between the target terminal device and the second network device. If the target path loss difference is smaller, it indicates that the wireless channel environment change of the target secondary carrier between the target terminal device and the second network device is smaller, and the target terminal device can obtain similar signal transmission quality in the current wireless channel environment without measuring the channel quality parameters again.
By periodically measuring the path loss parameters and determining the target path loss difference, whether the quality of a wireless channel between a target terminal and a target auxiliary carrier changes or not can be determined; if the target path loss difference meets the preset condition, the wireless channel environment between the target terminal and the target auxiliary carrier wave is not changed greatly within the preset time range, and the channel quality parameter of the latest activation time period before the target time meets the timeliness requirement; the channel quality parameter of the target terminal in the latest activation time period before the target time is determined as the target channel quality parameter, and data transmission with the target terminal is established according to the target channel quality parameter, so that the data transmission performance of the target terminal under the target auxiliary carrier can be guaranteed, the channel quality parameter measurement process before the target auxiliary carrier is activated can be omitted, the auxiliary carrier activation time delay is shortened, and the auxiliary carrier is quickly activated. When the target path loss difference is determined to meet the preset condition within the preset time range, actively sending a message to the first network equipment to request for quickly activating the target auxiliary carrier; the process of dynamically triggering the quick activation of the auxiliary carrier is realized through terminal measurement and message interaction between the terminal and the network equipment. In some embodiments, when the target path loss difference is greater than a first preset threshold, or a time interval between a first time period and a second time period is greater than a second preset threshold, the target terminal device does not send a fast activation request message to the second network device, at this time, the target terminal device executes a carrier activation procedure in the prior art, that is, the target terminal device needs to measure a channel quality parameter at the target time, and further, after acquiring the channel quality parameter at the target time, the second network device establishes data transmission (i.e., activates the secondary carrier) with the target terminal device.
The method comprises the steps that under the condition that a target path loss difference meets a preset condition, a target auxiliary carrier quick activation process is dynamically triggered through target terminal measurement and message interaction between a terminal and first network equipment; when the target path loss difference does not meet the preset condition, the conventional auxiliary carrier activation process is still adopted to ensure the data transmission performance of the target terminal; the method can realize the flexible selection of the auxiliary carrier activation mode based on the target path loss difference parameters, and can trigger the auxiliary carrier quick activation process in time to shorten the auxiliary carrier activation time delay as much as possible on the premise of ensuring the data transmission performance of the terminal. In some embodiments, as shown in fig. 4, in order to activate the target secondary carrier, the communication method provided in the embodiments of the present invention further includes the following steps S301 to S302.
S301, the first network device receives a quick activation request message sent by a target terminal device.
The quick activation request message comprises an identifier of target terminal equipment and an identifier of a target auxiliary carrier; the quick activation request message is used for instructing the first network equipment to send a quick activation instruction message to the second network equipment; the fast activation indication message is used for indicating the second network equipment to activate the target auxiliary carrier of the target terminal equipment according to the channel quality parameter of the target auxiliary carrier of the target terminal equipment in the first time period; configuring a target auxiliary carrier by the second network equipment; a first network device configures a target main carrier; and the second network equipment configures the target secondary carrier. Correspondingly, after receiving the quick activation request message, the first network device sends a quick activation indication message to the second network device; the quick activation indication message is used for indicating the second network equipment to activate the target auxiliary carrier of the target terminal equipment according to the channel quality parameter of the target auxiliary carrier of the target terminal equipment in the first time period; the quick activation indication message includes an identifier of the target terminal device and an identifier of the target secondary carrier.
The second network device receiving the fast activation indication message sent by the first network device includes the following two cases. If the first network device and the second network device are located in the same base station, the first network device forwards the quick activation request message to the second network device through an interaction process inside the base station. If the first network device and the second network device are located in different base stations, the first network device forwards the quick activation request message to the second network device through an interaction process between the base stations.
S302, the second network equipment activates the target auxiliary carrier of the target terminal equipment according to the channel quality parameter of the target auxiliary carrier of the target terminal equipment in the first time period.
As a possible implementation manner, the second network device takes the channel quality parameter in the first time period as the current channel quality parameter of the target terminal device, so as to obtain the current uplink and downlink channel quality parameters of the target terminal device. Further, the first network device determines the radio resource, the coding modulation mode and the spatial multiplexing mode of the target terminal device according to the current uplink and downlink channel quality parameters of the target terminal device, and controls the target terminal device to use the radio resource of the target auxiliary carrier for data transmission, so as to achieve the purpose of activating the target auxiliary carrier on the target terminal device.
It should be noted that, no matter the target terminal device is in the activated or deactivated state of the target secondary carrier, the channel quality parameters of the target secondary carrier in the historical activated period are always stored. Namely, at the target activation time, the target terminal device stores the channel quality parameter of the target secondary carrier of the first time interval.
The channel quality parameter may be a Channel Quality Indicator (CQI), a signal to interference plus noise ratio (SINR), a Reference Signal Receiving Quality (RSRQ), and the like. The embodiment of the present invention does not limit the specific channel quality parameters.
