Description

The method and apparatus that power headroom reporting (PHR) reports
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus that a kind of power headroom reporting (PHR) reports.
Background technology
In LTE (Long Term Evolution, Long Term Evolution) and former wireless communication system, in Yi Ge community, only have a carrier wave, in LTE system, maximum bandwidth is 20MHz, as shown in Figure 1.In LTE-A (LTE Advanced, the follow-up evolution of LTE technology) system, the peak rate of system has huge raising than LTE, requires to reach descending 1Gbps, up 500Mbps.If only using carrier wave that a maximum bandwidth is 20MHz cannot reach peak rate requires.Therefore, LTE-A system needs the operable bandwidth of terminal extension, introduced thus CA (Carrier Aggregation, carrier aggregation) technology, be about to a plurality of continuous or discrete carrier aggregation under same eNB (base station) together, be UE (User Equipment, user terminal) service, so that required speed to be provided simultaneously.These carrier waves that condense together are called CC (Component Carrier, member carrier).Each community can be a member carrier, and different e NBXia community (member carrier) can not polymerization.In order to guarantee that the UE of LTE can work under the carrier wave of each polymerization, each carrier wave maximum is no more than 20MHz.The CA technology of LTE-A as shown in Figure 2, under the base station of LTE-A, have 4 can polymerization carrier wave, base station can be simultaneously on 4 carrier waves and UE carry out transfer of data, to improve throughput of system.
When UE sends as shown in the A part in Fig. 3 with continuous P RB (Physical Resource Block, Physical Resource Block), at this moment UE can send with maximum power, such as 20dbm.When UE sends with discontinuous PRB, as shown in the B part in Fig. 3, at this moment total transmitted power of two PRB can not reach maximum power 20dbm, need to reduce, such as reducing 3dbm, this means UE at this moment maximum can only adopt 17dbm to send.This situation also there will be in the situation that uplink multi-carrier sends together.
In order to make base station know the dump power of UE, in prior art, provide PHR (Power HeadroomReport, power headroom reporting (PHR)) mechanism.In the R8/9 system of LTE, the definition of PHR is for PUSCH channel, namely PHR=Pcmax-P pUSCH.Wherein, Pcmax is that terminal meets the maximum transmission power that can allow in radio-frequency (RF) index situation.In LTE Rel-8, because up the continuous resource of support distributed, so the maximum power rollback difference of different terminals is very little, in 1-2dB left and right.The MAC CE design of PHR is as shown in table 1, and adopting LCID value is value corresponding to 11010 sign PHR.

In LTE Rel-8, defining Pcmax is:
P CMAX_L≤P CMAX≤P CMAX_H
P CMAX_L＝MIN{P EMAX-ΔT C，P PowerClass-MPR-A-MPR-ΔT C}
P CMAX_H＝MIN{P EMAX，P PowerClass}
Wherein, P eMAXby high level, configured P powerClassfor the power grade of UE, MPR (MaximumPower Reduction, maximum power drop-out value) and A-MPR (Additional Maximum PowerReduction, extra maximum power drop-out value) are stipulated T by agreement cby the frequency band feedback of using, determined.
Now, if UE is operated in multicarrier situation, for example UE is operated in two up CC simultaneously, and these two up CC belong to a PA, at this moment because two up MPR that send are together 3db.The maximum power level of supposing UE is 23dbm, and the transmitted power of the upper PUSCH (Physical Uplink SharedChannel, Physical Uplink Shared Channel) of first CC is 10dbm, and the PUSCH transmitted power on second CC is 7dbm.The MPR sending together due to two CC is considered in the PHR calculating of each CC, and the PHR on CC1 is PHR=23-10-3=10db, and the PHR of CC2 is PHR=23-7-3=13db.Now, base station can only probably be released according to the PHR on the PHR on first CC and second CC the upper UE of first CC and consume 13dbm, on second CC, consumed 10dbm, such two CC consume 23dbm altogether, therefore base station judges that this UE does not have power residue at present, and this UE has relative 3db power remaining in fact.That is to say, current, report PHR based on CC in the situation that, the power residue of UE cannot accurately be known in base station.
