Description

A kind of method and device controlling transmission power

Technical field

The present invention relates to field of communication technology more particularly to a kind of method and devices for controlling transmission power.

Background technique

Long term evolution (Long Term Evolution, LTE) time division duplex (Time Division Duplexing, TDD) in system, when the difference of same frequency can be used in uplink (Uplink, UL) and downlink (Downlink, DL) Gap (Time Slot, ST).Within the system, time-domain is made of radio frames (Radio Frame, RF), and radio frames pass through system Frame number (System Frame Number, SFN) is identified, and each radio frames are the subframe of 1 millisecond (ms) by 10 length (Subframe) it forms.

To meet the needs of uplink and downlink non-symmetrical service, can be configured up and down according to the type of uplink and downlink non-symmetrical service Row proportion (Uplink-Downlink Configuration).7 kinds of uplink and downlink proportions are shared in existing LTE TDD system, As shown in table 1.Wherein, D indicates that downlink subframe, U indicate that sub-frame of uplink, S indicate special subframe.It should be noted that special son Frame can be used as a kind of effective downlink subframe, and special subframe may include descending pilot frequency time slot (Downlink Pilot Tme Slot, DWPTS), protect time slot (Guard Period, GP) and uplink pilot time slot (Uplink Pilot Time Slot, UPPTS).

Table 1:

User equipment (User Equipment, UE) in sub-frame of uplink to evolved base station (Evolved Node B, ENB) send uplink signal before, need according to the eNB send transmission power control (Transmit Power Control, TPC it) orders, adjusts the transmission power of the uplink signal, so that the transmission power of the uplink signal can satisfy eNB reception The requirement of power.Wherein, which passes through Downlink Control Information (Downlink Control in downlink subframe Information, DCI) to the UE TPC command is sent, there are stringent sequential relationships between the DCI and the uplink signal.

In LTE system, generally on the basis of open Loop Power control, using feedback information as dynamic offset (offset), to realize close-loop power control.Uplink signal using close-loop power control includes Physical Uplink Control Channel Signal on (Physical Uplink Control Channel, PUCCH), Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) on signal or detection reference signal (Sounding Reference Signal, SRS).

Since the number of the sub-frame of uplink in a system-frame is possible to the number greater than downlink subframe, in DCI TPC command is possibly used for the transmission power of uplink signal at least two sub-frame of uplink of adjustment.For example, being in uplink and downlink proportion When 0, the number of sub-frame of uplink is 6, and it includes special subframe that the number of downlink subframe, which is 4().Therefore, when uplink and downlink proportion is 0, The number of sub-frame of uplink is greater than the number of downlink subframe, at this moment, it is necessary to which the TPC command in DCI can be used in adjustment at least two The transmission power of uplink signal in a sub-frame of uplink.Assuming that needing the uplink signal for carrying out power adjustment to be located at number is i(i=2, 3,4,7,8,9) in sub-frame of uplink, (uplink signal in hereinafter referred to as sub-frame of uplink i) carries out the sub-frame of uplink for being i to number The TPC command of power adjustment is i-K in number by eNB_PUSCHDownlink subframe (hereinafter referred to as downlink subframe i-K_PUSCH) interior to UE It sends, wherein K_PUSCHValue it is as shown in table 2.As known from Table 2, in the case where uplink and downlink proportion is 0, sub-frame of uplink 7 is corresponding K_PUSCHIt is 6, the corresponding K of sub-frame of uplink 8_PUSCHIt is 7, therefore, for adjusting uplink signal in sub-frame of uplink 7 and sub-frame of uplink 8 Although the TPC command of transmission power be all in downlink subframe 1(subframe 1 be special subframe, special subframe can also be used as one The effective downlink subframe of kind) introversion UE transmission, that is to say, that the TPC command that the eNB is sent in downlink subframe 1 is used for Adjust the transmission power of the uplink signal in sub-frame of uplink 7 and sub-frame of uplink 8.

Table 2:

In the prior art, in order to reduce the interference of minizone, need to control the transmission power of uplink signal.Due to cell Between uplink and downlink proportion may be different, so, the interference in certain subframes there may be base station to base station.For example, cell A Uplink and downlink proportion is 0, and the uplink and downlink of the cell B adjacent with cell A proportion is 1, then in subframe 4, terminal in cell A to ENB A in cell A sends uplink signal, and terminal of the eNB B into cell B in cell B sends downlink signal, at this moment, eNB The downlink signal that B is sent will generate very strong interference to the received uplink signal of eNB A.In order to reduce the interference of minizone, The sub-frame of uplink interfered in the same direction is generally divided into a sub-frame set, the sub-frame of uplink of incorgruous interference is divided into another height Frame set, the uplink signal in different sub-frame sets, carries out power adjustment with different TPC command values.Wherein, interference is wrapped in the same direction Interference of the uplink signal to the interference or downlink signal of uplink signal to downlink signal is included, incorgruous interference includes uplink signal under Interference of the interference or downlink signal of row signal to uplink signal.It should be noted that if a uplink signal is in uplink In frame i, and sub-frame of uplink i is divided into sub-frame set A, then the uplink signal also is located in sub-frame set A.

By the analysis to the prior art, inventor thinks that the existing technology has at least the following problems:

When uplink and downlink proportion is 0, the TPC command in downlink subframe 1 is for adjusting sub-frame of uplink 7 and sub-frame of uplink 8 The transmission power of interior uplink signal.But sub-frame of uplink 7 and sub-frame of uplink 8 are likely to be located at different sub-frame sets.When upper When row subframe 7 and sub-frame of uplink 8 are located at different sub-frame sets, UE can only be adjusted according to the TPC command in downlink subframe 1 The transmission power of uplink signal, can not adjust the transmitting of uplink signal in another sub-frame of uplink in row subframe 7 or sub-frame of uplink 8 Power, at this point, the transmission power of the uplink signal in another sub-frame of uplink will be unable to wanting for the reception power for meeting eNB It asks, so as to cause uplink signal abortive launch in another sub-frame of uplink.
