For the carrier aggregation of inside of base station, UE passes through PUCCH or PUSCH to base station report cycle CQI(Channel Quality Indicator, channel quality indicates)/SR(Scheduling Request, dispatch request), or SPS(Semi-Persistent Scheduling, semi-persistent scheduling) etc. upstream data time, base station adopts PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) mode controls the through-put power of these upstream datas, be one group of UE and distribute a RNTI(Radio Network Temporary Identity, Radio Network Temporary Identifier).When base station needs the through-put power adjusting these upstream datas, base station adopts this RNTI to carry out addressing in PDCCH, and at the CSS(Common Search Space of PDCCH, common search district) in send a DCI(Downlink Control Information comprising bit map, Downlink Control Information), after receiving this DCI to make UE, the TPC(Transmit Power Control with this UE can be found in this DCI, transmitting power control) corresponding to bit position, thus UE can adjust the through-put power of these upstream datas according to this TPC.

For the carrier aggregation across base station, namely MSA(Multiple Stream Aggregation is introduced, multithread is polymerized) after, if UE uses PUCCH or PUSCH at prothetic group station to report these upstream datas to dominant base, then these upstream datas of transmission on PUCCH or PUSCH to prothetic group station are needed to carry out the control of through-put power.

Embodiment one

The embodiment of the present invention provides a kind of control method of through-put power, relates to dominant base side, and as shown in Figure 1, the method can comprise:

S101, dominant base determine the TPC resource of UE, to be dominant base the be UE configuration of TPC resource, or for prothetic group station be that UE configures, dominant base and prothetic group station carry the transport service of UE simultaneously.

In carrier aggregation technology, the concept at dominant base and prothetic group station can for certain UE, and namely the dominant base of a UE is concerning another UE, may be the prothetic group station of another UE, accordingly, the prothetic group station of this UE also may be the dominant base of another UE.

Macro base station and little base station are the physical concept of base station, and wherein, macro base station is the website that coverage and transmitting power are larger; Little base station is the website that coverage and transmitting power are relatively little.

In the embodiment of the present invention, suppose for certain fixing UE, macro base station is the dominant base that this UE selectes, little base station is the prothetic group station that this UE selectes, certain community that UE is selected in the community of dominant base is simultaneously called main plot, and certain community that UE selectes in the community at prothetic group station is called auxiliary community.Wherein, community is the zones of different that base station uses different electromagnetic wave coverings.

When UE sends upstream data on the PUCCH of auxiliary community, if UE is in mobile status, then the UE that prothetic group station receives also can change along with the movement of UE position in the through-put power of the PUCCH of auxiliary community.But in order to not affect the communication of this UE and other UE, this UE that prothetic group station receives must control in a preset range in the through-put power of the PUCCH of auxiliary community.If UE is near prothetic group station, then the UE that prothetic group station receives just increases in the through-put power of the PUCCH of auxiliary community; Contrary, if UE is away from prothetic group station, the UE that then prothetic group station receives just reduces in the through-put power of the PUCCH of auxiliary community, if when the through-put power of this upstream data that prothetic group station receives is increased or decreased to outside preset range, prothetic group station will determine to adjust the through-put power of UE at the PUCCH of auxiliary community, and the UE received to make prothetic group station drops in this preset range in the through-put power of the PUCCH of auxiliary community.

Be understandable that, if the UE that prothetic group station receives increases to outside preset range in the through-put power of the PUCCH of auxiliary community, namely the UE that receives of prothetic group station is too strong in the through-put power of the PUCCH of auxiliary community, then may cause interference to the communication of other UE, affect the proper communication of other UE; If the UE that prothetic group station receives is decreased to outside preset range in the through-put power of the PUCCH of auxiliary community, namely the UE that receives of prothetic group station is too weak in the through-put power of the PUCCH of auxiliary community, then may increase the communication bit error rates of this UE, affect the proper communication of this UE.

In the present embodiment, the power attenuation of UE the through-put power of the PUCCH of auxiliary community deducts the process being sent to prothetic group station from UE, is UE that prothetic group station the receives through-put power at the PUCCH of auxiliary community.

Especially, the embodiment of the present invention illustrates the control method of the through-put power that the embodiment of the present invention provides in the through-put power of the PUCCH of auxiliary community for UE, and for UE the control of the through-put power of the PUSCH of auxiliary community and UE similar in the control method of the through-put power of the PUCCH of auxiliary community, the present invention repeats no more.

It should be noted that, the upstream data that above-mentioned UE sends on the PUCCH of auxiliary community can comprise CQI/SR, and the upstream data that UE sends on the PUSCH of auxiliary community can comprise SPS.

When adjusting UE when the through-put power of the PUCCH of auxiliary community, dominant base need determine the TPC resource of UE, and can be dominant base the be UE configuration of this TPC resource also can be prothetic group station is UE configuration, wherein, dominant base and prothetic group station carry the transport service of UE simultaneously.

Concrete, if the TPC resource of dominant base needed for UE configuration UE, then dominant base can, according to the instruction at prothetic group station, be UE configuration TPC resource; If the TPC resource of prothetic group station needed for UE configuration UE, then prothetic group station is after UE configures TPC resource, and this TPC resource can be sent to dominant base by prothetic group station, can know TPC resource needed for UE to make dominant base.

Optionally, TPC resource can comprise the mark of UE and the bit map information of DCI, and monitor PDCCH for the CSS of UE in main plot and obtain TPC, wherein, main plot provides service by dominant base.

Optionally, the mark of UE can be the bit map information of the RNTI of UE in auxiliary community, DCI is bit position corresponding with TPC in the bit map of DCI.

Optionally, when UE be assigned with when auxiliary community is identical with the RNTI in main plot, by the bit map information instruction UE of DCI, dominant base identifies that TPC, TPC represent by the different bit positions taken in the bit map of DCI the through-put power that the PUCCH needs of UE in auxiliary community adjust.

In the embodiment of the present invention, the TPC resource that above-mentioned dominant base is sent to UE can be used for the through-put power of dominant base control UE at the PUCCH at prothetic group station.Separately, if dominant base need control UE in the through-put power of the PUCCH of dominant base, then dominant base also can configure another part of TPC resource for UE.

As shown in Figure 2, for be assigned with as UE when auxiliary community is identical with the RNTI in main plot, the schematic diagram that this TPC resource indicates another part, the bit position and this of this TPC in the bit map of DCI TPC resource to indicate the bit position of another TPC in the bit map of DCI different.

Optionally, when UE is different from the RNTI of UE in main plot at the RNTI of auxiliary community, dominant base indicate UE to identify by the RNTI of UE in auxiliary community TPC, TPC represent the through-put power that the PUCCH needs of UE in auxiliary community adjust.

S102, dominant base send TPC resource to UE and for adjusting the TPC of UE in the through-put power of the PUCCH of auxiliary community, to make UE according to TPC resource identification TPC, and adjust this through-put power according to TPC, auxiliary community is for being provided the community of service by prothetic group station.

After dominant base determines the TPC resource of UE, this TPC resource is sent to UE by dominant base, and be also sent to UE by being used for adjusting UE at the TPC of the through-put power of the PUCCH of auxiliary community, TPC needed for UE can be gone out according to this TPC resource identification to make UE, and adjust the through-put power of UE at the PUCCH of auxiliary community according to TPC, thus this through-put power making prothetic group station receive meets above-mentioned preset range, and then do not affect normal communication, wherein, auxiliary community is for being provided the community of service by prothetic group station.

Optionally, as shown in Figure 3, before dominant base sends TPC resource to UE, said method can also comprise:

S103, dominant base receive the TPC adjustment instruction from prothetic group station, and TPC adjustment instruction is used to indicate UE and adjusts this through-put power.

When prothetic group station determines need adjust UE when the through-put power of the PUCCH of auxiliary community, prothetic group station can generate a TPC adjustment instruction according to the exchange format between dominant base and prothetic group station, and this TPC adjustment instruction is sent to dominant base, after dominant base receives the TPC adjustment instruction from prothetic group station, this TPC is adjusted instruction and is sent to UE by dominant base again, adjusts this through-put power for instruction UE.

It should be noted that, the exchange format between dominant base from prothetic group station can be different, also can be identical, and the present invention does not limit.If the exchange format between dominant base and prothetic group station is different from the exchange format between dominant base and UE, this TPC then can be adjusted instruction and be converted to the TPC corresponding with the exchange format between dominant base and UE and adjust and indicate by dominant base; If the exchange format between dominant base and prothetic group station is identical with the exchange format between dominant base and UE, dominant base then can be changed without the need to adjusting instruction to this TPC, and directly this TPC adjustment instruction is sent to UE.

Optionally, the exchange format between dominant base and prothetic group station can be determined by dominant base, also can be determined by prothetic group station.If the exchange format between dominant base and prothetic group station is determined by dominant base, then the exchange format determined can be sent to prothetic group station by dominant base; If the exchange format between dominant base and prothetic group station is determined by prothetic group station, then the exchange format determined can be sent to dominant base by prothetic group station.Accordingly, the exchange format between dominant base and UE is sent to UE after being determined by dominant base.

Exemplary, if the exchange format between dominant base and prothetic group station is 3 bits, then prothetic group station just generates the TPC adjustment instruction of 3 bits, and the TPC that namely prothetic group station generates adjusts instruction and takies 3 bits.Such as, if TPC adjustment indicates 3 bits taken to be " 010 ", then represent and need UE that UE is raised 2 units in the through-put power of the PUCCH at prothetic group station.If the exchange format between dominant base and UE is 1/2 bit, then the TPC adjustment instruction that prothetic group station is just sent by dominant base is converted to the TPC adjustment instruction of 1/2 bit, and the TPC namely after dominant base conversion adjusts instruction and accounts for 1/2 bit.
