In step S101, network equipment is such as: base station, because UE place environment can constantly change, such as: change in location, sound size variation etc., thus cause network equipment when receiving UE side signal, UE side optimum output power also can be different, so network equipment is after the signal receiving UE transmission, will according to the quality of the signal received, to the instruction of UE transmission power control, the transmission power adjustment step-length comprised in power control instruction can be positive number, such as: 1dB, 1.2dB, in this case, UE side is needed to improve power output, transmission power adjustment step-length also can be negative, such as :-1dB ,-1.2dB etc., in this case, needs UE side to reduce power output.
As further preferred embodiment, before step S103, method also comprises:
Determine the specified adjustment step-length of UE in the transmitting power gain adjustment value of the current time according to UE and the transmitting power gain adjustment value of UE subsequent time before, method also comprises:
When to be based upon voltage be the first value, the mapping table of the power variation between the transmitting power gain adjustment value of subscriber equipment, power output and different transmitting power gain adjustment value, such as, mapping table as shown in table 1:
Table 1
Under normal circumstances, electronic equipment can by changing transmitting power gain adjustment value, and then change the power output of electronic equipment, and then when electronic equipment adopts different transmitting power gain adjustment value, the difference of power output can be there is, such as: as shown in table 1, when the transmitting power gain adjustment value of electronic equipment is 41, its power output-32.0038dBm; And when transmitting power gain adjustment value is reduced to 40 by 41 by electronic equipment, when the voltage of PA is constant, its power output is-32.9577dBm, also namely when the transmitting power gain adjustment value of electronic equipment is reduced to 40 by 41, its adjacent power output difference caused is then-0.95389dB, so can be adjusted the power output of electronic equipment by the transmitting power gain adjustment value changing electronic equipment.
In step S102, if transmission power adjustment step-length is positive number, on the basis of the transmitting power gain adjustment value of current time, then increase certain value to determine the transmitting power gain adjustment value of subsequent time, such as: suppose that the transmitting power gain adjustment value of current time is 40, if transmission power adjustment step-length is 1.2dB, so, the transmitting power gain adjustment value of subsequent time is then 41; If transmission power adjustment step-length is-1.2dB, so, the transmitting power gain adjustment value of subsequent time is then 39, and certainly, above-mentioned numerical value is only a citing, not as restriction.
Under normal circumstances, it is 1 that the transmitting power gain adjustment value of subsequent time and the transmitting power gain adjustment value of current time fluctuate up and down, if but before step S102, just set up the transmitting power gain adjustment value of subscriber equipment, the words of the mapping table of the power variation between power output and different transmitting power gain adjustment value, also the transmitting power gain adjustment value in next moment can be determined by the mode of tabling look-up, such as: if the absolute value of transmission power adjustment step-length (is assumed to be 0.5dB, can certainly be other values) be less than the difference power that brings of transmitting power gain adjustment value fluctuation 1 of current time, then the transmitting power gain adjustment value of subsequent time is that the transmitting power gain adjustment value of current time adds deduct 1, if and the absolute value of transmission power adjustment step-length (is assumed to be 1.8dB, can certainly be other values) much larger than the difference power that brings of transmitting power gain adjustment value fluctuation 1 of current time, and close to the words of difference powers that the transmitting power gain adjustment value fluctuation 2 of current time brings, then the transmitting power gain adjustment value of subsequent time is that the transmitting power gain adjustment value of current time adds deduct 2, the like.
