Background technology
In LTE R10 version, planned to support UE (User Equipment at present, user terminal) up PRB (Physical Resource Block, Physical Resource Block) discontinuous distribution, be included in and on same carrier wave, send PUCCH (Physical Uplink Control Channel simultaneously, Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel).After introducing this mechanism, existing PHR (power headroom report, margin of power is reported) is reported and will produce certain influence.When UE adopts discontinuous PRB to send, due to the restriction of out-of-band radiation index, terminal need to adopt certain back-off, can not send with original maximum transmit power, and need to reduce a part of power.As shown in Figure 1, when UE sends with continuous P RB, as shown in the A part of Fig. 1, at this moment UE can send with maximum power, such as 20dbm; When UE sends with discontinuous PRB, as shown in the B part of Fig. 1, 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.
PHR mechanism is that UE is to a kind of mechanism of base station report UE transmitted power and maximum work rate variance.In the R8/9 system of LTE, the definition of PHR for be PUSCH channel, PHR=Pcmax-PPUSCH namely, 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.
In the MAC CE of PHR design at present, as shown in table 1, adopt the sign that LCID value is 11010.

In prior art, PHR trigger condition comprises:
1, when up new data needs to send, and the Pathloss that UE surveys changes higher than the thresholding of setting, and prohibitPHR-timer is overtime, triggers PHR;
2, after periodicPHR-timer is overtime, trigger PHR;
3, when carrying out reprovision, the parameter of PHR triggers PHR.
In LTE Rel-10 and follow-up system, introduced multiple uplink combination, for example uplink of discontinuous PRB (comprising that PUCCH and PUSCH transmit simultaneously, discrete PUSCH scheduling of resource etc.).Terminal maximum power rollback for uplink, depends on the realization of terminal: the maximum power rollback of different terminals in identical uplink situation may be different to a certain extent; Same terminal maximum power rollback of (for example continuous P RB transmission and discontinuous PRB transmission) under different uplink combined situation is also possible different.This difference in some cases may be larger, 4-6dB for example, or more.As shown in Figure 2, existing PHR reports mechanism can not reflect back-off situation, and UE back-off situation cannot be known in base station, causes thus base station reasonably not dispatch UE.

It should be noted that, in the present embodiment, step 301 is not necessary condition, when the reason due to outside discontinuous PRB scheduling causes user terminal generation back-off, the method that in the present embodiment, user terminal sends PHR report according to the PHR reporting policy of configuration to described network side stands good.
The embodiment of the present invention two provides a kind of Poewr control method, as shown in Figure 4, comprises the following steps:
Concrete, PHR trigger information can be arranged on the idle bit in existing PDCCH format form, also can be set to increases PHR trigger information on the basis of existing DCI format, or defines a new PDCCH format (for the ULgrant of uplink scheduling) who comprises PHR trigger information.When the discontinuously dispatching UE of base station, PHR trigger information is carried in base station in the PDCCH signaling sending to UE.
Concrete, in the embodiment of the present invention, base station and UE need to arrange the position of PHR trigger information in PDCCH signaling, and UE approximately fixes on specific position probing according to this and whether stores PHR trigger information.In addition, between base station and UE, also need the time relationship of arranging between PHR report and PHR trigger triggering to meet certain timing relationship, this timing relationship can and Rel-8 in UL grant and the time relationship between PUSCH be consistent, also can be inconsistent.UE sends PHR report after receiving PHRtrigger information to base station according to this time relationship.
Take FDD system as example, suppose that the time relationship between PHR report and PHR trigger triggering is 4, interval subframe, apply after above-mentioned Poewr control method, in UL grant, increase 1bit PHR trigger information, UE receives after the UL grant that comprises this PHR trigger information at descending sub frame k, at k+4 sub-frame of uplink, reports PHR.This PHR is that the signal transmission situation based on k+4 sub-frame of uplink is calculated.
Base station is reported UE is dispatched according to PHR.
The embodiment of the present invention three provides a kind of Poewr control method, as shown in Figure 5, comprises the following steps:
In the embodiment of the present invention, new scheduling MAC CE signaling need to be set, arrange the MAC CE scheduling timing relationship between reporting with PHR, this timing relationship can, for correctly receiving first the discontinuous PRB scheduled transmission after triggering MACCE, can be also other timing relationships simultaneously.When the discontinuously dispatching UE of base station, PHR trigger information is carried in base station in the MAC CE signaling sending to UE.
Concrete, UE obtains after the PHR trigger information of carrying in MAC CE signaling, and timing relationship according to a preconcerted arrangement sends PHR report to base station.
For example, the timing relationship of take reports PHR to be reported as example when correctly receiving first the discontinuous PRB scheduled transmission triggering after MAC CE, UE receives that at descending sub frame k scheduling triggers the MAC CE signaling of back-off report, UE carries out first discontinuous PRB transmission at sub-frame of uplink k+n, so UE reports the situation of back-off at sub-frame of uplink k+n.The PHR of this back-off is that the signal transmission situation based on k+n sub-frame of uplink is calculated.Reporting here can also arrange the situation that a MAC CE represents back-off, such as being set to P-PHR.
The embodiment of the present invention four provides a kind of Poewr control method, as shown in Figure 6, comprises the following steps:
For example, network side carries out discontinuous PRB scheduling with the modulation levels of 16QAM, and discontinuous PRB interval is while being 20 PRB, and UE reports back-off situation; Network side carries out discontinuous PRB scheduling with the modulation levels of QPSK, and discontinuous PRB interval is while being 20 PRB, and UE reports back-off situation; When network carries out discontinuous PRB scheduling with the modulation levels of 16QAM again, and discontinuous PRB interval is while being 20 PRB, and UE still reports back-off situation.
The embodiment of the present invention five provides a kind of Poewr control method, as shown in Figure 7, comprises the following steps:
For example, network side carries out discontinuous PRB scheduling with the modulation levels of 16QAM, and discontinuous PRB interval is while being 20 PRB, and UE reports back-off situation; Network side carries out discontinuous PRB scheduling with the modulation levels of QPSK, and discontinuous PRB interval is while being 20 PRB, and UE judgement did not report with this discontinuous PRB dispatches corresponding back-off situation, to network side, reports back-off situation; When network carries out discontinuous PRB scheduling with the modulation levels of 16QAM again, and discontinuous PRB interval is while being 20 PRB, due to UE judgement reported this discontinuous PRB back-off situation now UE no longer report back-off situation.
The embodiment of the present invention six provides a kind of Poewr control method, as shown in Figure 8, comprises the following steps:
For example, in the process of repeatedly uplink, if the back-off value of end side differs, be less than some levels (for example N dB), do not trigger PHR and report, only when back-off value differs by more than N dB, just report.
While adopting the mode of above-described embodiment four to six, UE self triggers PHR report, the situation that a MACCE represents back-off is set, such as being set to P-PHR.When network side carries out discontinuous PRB scheduling, UE initiatively triggers reporting of MAC CE P-PHR, makes network side know the back-off situation of UE in this case.The modulation system of and UE main due to the situation of UE back-off, relevant with discontinuous PRB interval, exist back-off situation is quantized may, therefore can each discontinuous PRB dispatch and all report PHR; Also can, to certain back-off situation having reported, no longer report; Or also can when changing a lot, back-off value report again.
In the embodiment of the present invention, when network side carries out discontinuous PRB scheduling to user terminal, user terminal sends PHR report according to the PHR reporting policy of configuration to network side, makes network side know the back-off situation of user terminal, thereby can make base station reasonably dispatch UE.
It should be noted that, the method providing in the above embodiment of the present invention, can also be combined into new Poewr control method, for example base station sends and carries after the PDCCH signaling or MAC CE signaling of PHR trigger information to UE, UE resolves PDCCH signaling or MAC CE signaling is obtained PHR trigger information, but send PHR report to network side before, UE also needs to judge whether to be greater than preset value, just to network side, send PHR report judgment result is that be in the situation that.
PHR report method based on as above, the back-off value of a UE in different uplink situations can be estimated to obtain in base station, specifically by the PHR that relatively this UE reports in different subframes, obtains.For example, UE adopts continuous PUSCH resource to distribute at sub-frame of uplink x, and transmitting power is Ppusch_x, and the PHR that this subframe reports is PHR_x=Pmax-Ppusch_x; At sub-frame of uplink y, adopt discrete PUSCH resource to distribute, transmitting power is Ppusch_y, and the PHR that this subframe reports is PHR_y=Pmax-Pbackoff_y-Ppusch_y.Base station can obtain the back-off value Pbackoff_y of this terminal in the such uplink situation of similar subframe y by the difference of PHR_x and PHR_y like this, can be used as reference when follow-up ascending resource scheduling.The PHR each time here reports and can adopt aforesaid two class methods (being the situation that base station scheduling triggers or UE oneself triggers).The terminal power rollback value in various transmission situations, by obtaining the PHR value in different transmission situations, can roughly be estimated in base station, carries out reference in follow-up scheduling.
