Embodiment
Be described in further detail below in conjunction with the technical scheme of the drawings and the specific embodiments each embodiment of the present invention.
In the embodiment of the invention, determine the Initial Trans of the DPCCH of upstream auxiliary carriers according to the current transmit power of up main carrier.Can guarantee the accuracy of the Initial Trans of the DPCCH of upstream auxiliary carriers in the multicarrier system, help shortening the synchronous time of upstream auxiliary carriers.
Fig. 1 is the method flow schematic diagram of power control under the multi-carrier mode according to an embodiment of the invention.As shown in Figure 1, this method can comprise:
In the present embodiment, consider that two up-link carriers of DC-HSUPA use adjacent 5MHz bandwidth, frequency interval has only 5MHz, and frequency difference is little.Therefore, when activating upstream auxiliary carriers, the initial power of DPCCH can be determined according to the current transmit power of the DPCCH of up main carrier.
For example, behind the two carrier modes that activate UE, begin the synchronizing process of upstream auxiliary carriers, the Initial Trans of the DPCCH of upstream auxiliary carriers can be identical with the transmitting power of the DPCCH current time of up main carrier, or have a power bias amount.The Initial Trans that it will be understood by those skilled in the art that the DPCCH of upstream auxiliary carriers can be the transmitting power of first time slot of the DPCCH emission of upstream auxiliary carriers; The transmitting power of the DPCCH current time of up main carrier can be the transmitting power of the current time slots of the up main carrier corresponding with first time slot of the DPCCH of upstream auxiliary carriers emission.
Wherein, this power bias amount can by network equipment (such as, Node B or RNC) notice UE when activating two carrier mode, also can pre-configured certain fixed value.
When there is a power bias amount in the transmitting power of the current time of the DPCCH of the Initial Trans of the DPCCH of upstream auxiliary carriers and up main carrier, can determine the Initial Trans of upstream auxiliary carriers DPCCH by following formula:
Secondary_DPCCH_Initial_power＝Primary_DPCCH_Current_Power+Pp-s
Wherein, Secondary_DPCCH_Initial_power is the Initial Trans of the DPCCH of upstream auxiliary carriers, and Primary_DPCCH_Current_Power is the current transmit power of the DPCCH of up main carrier, and Pp-s is the power bias amount.
It will be understood by those skilled in the art that, upstream auxiliary carriers is activated when UE enters the CELL-DCH state, the DPCCH of up main carrier and upstream auxiliary carriers may begin emission (in other words simultaneously, be activated simultaneously), the current transmit power of the DPCCH of up main carrier also is its Initial Trans at this moment; Upstream auxiliary carriers is activated after UE enters the CELL-DCH state, and the current transmit power of the DPCCH of up main carrier can not be its Initial Trans at this moment.
After the DPCCH of upstream auxiliary carriers begins emission according to the Initial Trans of determining, UE begins the closed power control procedure, that is: can adjust the transmitting power of the DPCCH of upstream auxiliary carriers by the power control command (TPC, Transmit PowerControl) that receives.
In the present embodiment, the Initial Trans of the DPCCH of upstream auxiliary carriers is determined according to the current transmit power of the DPCCH of up main carrier, can guarantee the accuracy of Initial Trans of the DPCCH of upstream auxiliary carriers, help shortening and finish the synchronous time of upstream auxiliary carriers, improve systematic function.
Among other embodiment of the present invention, behind the two carrier modes that activate UE, begin the synchronizing process of auxilliary carrier wave, the Initial Trans of the DPCCH of upstream auxiliary carriers can also be that up main carrier disposes or be the independent parameter DPCCH_Power_offset that disposes of upstream auxiliary carriers according to the network side high level, and the decision of the measurement result of the CPICH of upstream auxiliary carriers.The formula of the Initial Trans of the DPCCH of a calculating upstream auxiliary carriers is as follows:
Secondary_DPCCH_Initial_power＝DPCCH_Power_offset-Secondary_CPICH_RSCP
Wherein, Secondary_DPCCH_Initial_power is the Initial Trans of the DPCCH of auxilliary carrier wave; Secondary_CPICH_RSCP is obtained the measurement result of the auxilliary descending CPICH channel of carrier wave by UE; DPCCH_Power_offset is the DPCCH power offset of up main carrier configuration or the power bias amount that upstream auxiliary carriers disposes separately.
It will be appreciated by those skilled in the art that, if the network side high level is the auxilliary independent configuration parameter DPCCH_Power_offset of carrier wave, then may need network side to issue the relevant information element (IE of UE, Information element), as IE " Secondary DPCCH Power offset ", notify this power bias amount.
