Description

The control method and device of ascending power

Technical field

The present invention relates to the communications field, in particular to a kind of control method and device of ascending power.

Background technology

Current Long Term Evolution (Long Term Evolution, referred to as LTE) is deployed in mandate carrier wave and runed. But with the rapid growth of data service, in the near future, authorize frequency spectrum will again to bear lower such huge number According to amount.Therefore need to dispose LTE in an unlicensed spectrum, the data flow authorized in carrier wave is shared by unlicensed spectrum Amount.

In addition, being also the presence of many advantages for unlicensed spectrum.For example, unlicensed spectrum has following feature And advantage:

1st, free/low expense (non-frequency spectrum need not be bought, frequency spectrum resource is zero cost).

2nd, requirements for sale is low, and cost is low (personal, enterprise can participate in deployment, and the equipment of equipment vendor can be arbitrarily).

3rd, shared resource (multiple different systems all run when wherein or same system different operators operation wherein when, It is contemplated that the mode of some shared resources, improves spectrum efficiency).

4th, wireless access technology is more (across different communication standards, cooperation is difficult, and network topology is various).

5th, wireless access website is more (number of users is big, and cooperation difficulty is big, and centralized management expense is big).

6th, using it is many (multi-service, which is mentioned, to run wherein, for example machine to machine (Machine to machine, Referred to as M2M), vehicle to vehicle (Vehicle to vehicle, referred to as V2V)).

Above-mentioned essential characteristic, it is probably one important evolution tendency of wireless communication system to determine unlicensed spectrum. In the 3GPP RAN1 Release13 stages, LAA subject under discussion discussion is introduced, to unlicensed spectrum answering in downlink transfer With some common recognitions have been reached, in the stages of Release 14, it will application of the unlicensed spectrum in uplink is discussed.

For uplink, in order to ensure certain QoS demand, on the premise of ensureing to the accurate reception of upstream data Transmission power is reduced as far as possible, and tackles the near-far interference of user, and uplink power control is indispensable, according to LTE Release The regulation of 13 agreements, gives the uplink power control for different up channel/signals, and emphasis is included to lower channel/signal Uplink power control formula:

PSRS,c(i)=min { PCMAX,c(i),PSRS_OFFSET,c(m)+10log10(MSRS,c)+PO_PUSCH, c(j)+αc(j)·PLc+fc(i)}

It should be noted that with each part in upper signal channel/signal uplink power calculation, being assisted in LTE Release 13 Clear and definite parsing is given in view.

For Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH) power control, PPUSCH,c(i)、fc(i)、ΔTF,c(i) being can be with the parameter of dynamic change, MPUSCH,c(i) correspondence PUSCH frequencies Domain RB numbers, fc(i) it is the power control dynamically-adjusting parameter notified in UL Grant, ΔTF,c(i) by modulation and coding strategy The decision of (Modulation And Coding Scheme, referred to as MCS) and PUSCH transmission contents attribute, its His parameter is all to be semi-statically configured parameter by what high-level signaling was set.

For detection reference signal (Sounding Reference Signal, referred to as SRS) power control adjustment, only fc(i) Being can be with the parameter of dynamic change, and other specification is all semi-statically configured by high-level signaling, and fc(i) it is PUSCH Transmission power control (Transmit Power Control, referred to as TPC) in power control, once therefore some subframe PUSCH power spectral density (Power Spectral Density, referred to as PSD) is determined, if the subframe is also sent out Send SRS, then subframe SRS PSD is just also determined, then SRS transmit powers can not be achieved independently of in fact The dynamic change of PUSCH transmit powers.

Discounting for semi-static uplink scheduling, conventional uplink scheduling is list frame scheduling, i.e., terminal is in descending sub frame The UL Grant of a correspondence itself are received, uplink authorization scheduling UL Grant indicate correspondence subsequent one sub-frame of uplink PUSCH transmission, in Release 14 UL LAA, with reference to the characteristics of UL LAA, up many subframe schedulings It is a kind of more efficient mode, it is more likely that apply in UL LAA, in up many subframe schedulings, terminal is one Individual descending sub frame can receive one or more UL Grant, the PUSCH scheduling of the follow-up multiple continuous subframes of correspondence, then Once successful up listem-before-talk UL LBT are only needed to, terminal can just be continuously transmitted according to UL Grant instruction Multiple PUSCH subframes, substantially increase uplink efficiency, and reduce propagation delay time.But adjusted in up many subframes In degree, if many subframes are continuously transmitted, UL LBT are during which no longer carried out, then (such as LTE in multiple coexistence of systems System and WiFi system, or multiple LTE systems), if the PUSCH/SRS of each subframe is according to the sides of Release 13 Formula independently carries out power control, may bring some problems.

When LAA systems send PUSCH/SRS, different system node may be performed because there is data transfer demands Listem-before-talk (Listen Before Talk, referred to as LBT) clear channel assessment (CCA) (Clear Channel Assessment, Referred to as CCA), but different system node is specific during the PUSCH transmissions of LAA systems or in the SRS transmission phases Between perform LBT CCA, LAA systems be fathomless, it is assumed that the CCA thresholdings of different system be CCA_ED, certain Subframe PUSCH hairs set power as P_PUSCH, and subframe SRS transmit powers are P_SRS, if P_PUSCH More than P_SRS, then different system node may be unsuccessful in PUSCH domains CCA, but in SRS domains CCA successes, When this happens, different system can start busy channel in SRS domains, and this may not have in itself to SRS demodulation What influence, but if the continuous busy channel of different system to the PUSCH domains of next subframe (are no longer done extra CCA), then the transmission of different system data can be produced with LAA PUSCH transmissions to conflict, and causes hidden node problem, from And the demodulation mistake of two systems may be caused.

For the above mentioned problem in correlation technique, not yet there is effective solution at present.
