Description

A kind of ascending power control method, Apparatus and system

Technical field

The present invention relates to the communication technology, relate in particular to a kind of ascending power control method, Apparatus and system.

Background technology

LTE (Long Term Evolution, Long Term Evolution) and LTE-A (LTE-Advanced, enhancing LTE) in the system, SRS (sounding reference signal, uplink detection reference signal) thus uplink scheduling is carried out in the measurement that can be used for uplink signal-channel quality, also can be used for utilizing channel reciprocity to obtain descending channel information, thereby carry out descending scheduling and transmission.In the heterogeneous network, up-downgoing transmission can independently be carried out, and namely the residential quarter of uplink receiving terminal data and the descending residential quarter that sends data to terminal are not same residential quarters.At this moment, the SRS that sends for uplink with for the SRS of downlink transfer owing to be to receive in different residential quarters, the requirement of its transmitting power also can be different.Therefore, need the base station to pass through DCI (downlink control information, down physical layer control information) the SRS transmitted power is dynamically adjusted respectively to satisfy different measurement demands.

At isomery CoMP (coordinated multiple point transmission as shown in Figure 1, coordinated multipoint transmission) in the scene, affixing one's name to LPN (Low Power Point at the intra-zone that macro base station (Macro) covers, low power nodes), being used for carrying out focus covers.Usually the transmitting power of macro base station is far above the transmitting power of LPN, and the Macro downstream signal that causes some to receive from the terminal of LPN close to more is better than the downstream signal of LPN, and the PDSCH of this part terminal (Physical Downlink Shared Channel) can send from macro base station.Because terminal distance L PN is nearer, the terminal quality of uplink signal that LPN receives can be higher than the quality of uplink signal that macro base station receives, so the PUSCH of this part terminal (Physical Uplink Shared Channel) is received by the LPN node.In utilizing the downlink transfer scheme of channel reciprocity, terminal need to send the SRS signal to help the downlink channel condition information of base station acquisition from the macro base station to the terminal to macro base station.That is to say what SRS signal that terminal sends and upstream data were received by the different network equipments.

Have at present two kinds of dissimilar SRS send modes: cycle SRS send mode and aperiodic the SRS send mode.The former need to be disposed by the base station transmission cycle of SRS, and terminal disposes according to this, periodically sends SRS; The latter is triggered by PDCCH by the base station, and terminal only sends SRS one time after triggering.The uplink transmission power of SRS is:

P _SRS，c(i)＝min{P _CMAX，c(i)，P _{SRS_OFFSET，c}(m)+10log ₁₀(M _SRS，c)+P _{O_PUSCH，c}(j)+α _c(j)·PL _c+f _c(i)}

Wherein, P _CMAXThe maximum transmit power of UE, P _{SRS_OFFSET, c}(m) be SRS transmitted power adjusted value, poor in order to the transmitted power of adjusting PUSCH and SRS.Its span is determined by higher level parameters Ks, when Ks=0, its step-length is 1.5dB, and span is [10.5,12], when Ks=1.25, its step-length is 1dB, and span is [3,12], concrete value is notified by high-level signaling, and the indication cycle sends SRS and sends the signal of SRS aperiodic respectively for m=0 and m=1; MSRS is the transmission bandwidth of SRS, P _{O_PUSCH}(j) be Cell Broadcast CB parameter P _{O_Nominal_PUSCH}(j) with the high-rise power control parameters P of UE special use _{O_UE_PUSCH}(j) and, PL _cThat descending path loss is estimated, measured by the UE end, its value is the CRS transmitted power of descending base station and the ratio of the RSRP that UE reports, and f (i) is the power control parameters of closed loop, obtains by the transmission power control commands among the DCI format0/4/3/3A (TPC order).F (i) can be that accumulated value also can be absolute value.Wherein, the used parameter of closed-loop power control mainly is P _{O_UE_PUSCH}(j) and f (i).The former is by 4 bit high-level signalings notice, and scope is [7,8], step-length 1dB, and the latter can be the accumulated value to a front value: f (i)=f (i-1)+δ by the PDCCH signaling _PUSCH, also can be absolute value f (i)=δ _PUSCHδ as shown in table 1, that the TPC of different DCI indicatings obtains _PUSCHValue is different:

Table 1TPC and δ _PUSCHThe mapping relations table of value

Closed-loop power control parameter f (i) is that SRS and PUSCH share in the prior art, namely also can affect the transmitting power of SRS to the adjustment of PUSCH transmitting power, may produce unnecessary mistake in some cases.For example, the channel quality of PUSCH link improves, and the base station can order control terminal to reduce accordingly the transmitting power of PUSCH by TPC, namely reduces the value of f (i).The target that the SRS target receives residential quarter and PUSCH receives the residential quarter not simultaneously, and the quality of SRS link may not improve.But the f that reduces (i) value also can reduce the transmitting power of SRS, thereby affects the quality that SRS sends.

Need to the closed-loop power control parameter of SRS and the closed-loop power control Decoupled of PUSCH, namely introduce the closed-loop power control parameter f of SRS special use for addressing this problem _SRS(i).By the TPC order of corresponding SRS special use, can carry out independently power adjustment to SRS, thereby not be subjected to the impact of PUSCH closed-loop power control.At this moment, the power control formula of SRS should change to:

P _SRS，c(i)＝min{P _CMAX，c(i)，P _{SRS_OFFSET，c}(m)+10log ₁₀(M _SRS，c)+P _{O_PUSCH，c}(j)+α _c(j)·PL _c+f _srs，c(i)}

At present, a kind of method of ordering to the TPC of terminal transmission SRS special use is the new DCI form of design, is specifically designed to the notice of SRS closed-loop power control parameter.But design the increase that new DCI can cause terminal PDCCH blind check number of times, increase the complexity of terminal.
