The forward direction power control commands of each of the links reported are held, or situation of change of base station forward emitting power etc. can be directly or indirectly anti-
The information for answering forward link to change can serve as forward link information.
Whether step S210, base station are reasonable to adjudicate the power being currently assigned on every strip antenna with a kind of algorithm, if
Need to adjust, and the amplitude of adjustment.The principle of algorithm design should follow：The preferable antenna of channel quality obtains more power
Distribution, to realize the allocation optimum of power resource.The specific embodiment of algorithm is seen below.
Caused new power control commands after judgement are issued control module corresponding to every strip antenna by step S212, base station.
Step S214, control module completes the execution to new power control command corresponding to per strip antenna.Power control commands
It is specific to perform the setting that the driving API of baseband chip by base station system when every 20ms writes frame, be called to complete new power control commands,
Execution is carried out by chip to operate.
Step S216, such as calling do not terminate, then circulation performs step S208 to step S214, according to step S214, due to
The renewal of power control commands is carried out per 20MS and performs response, i.e., since being analyzed Link Channel Quality, to court verdict is drawn, is arrived
Power control commands are sent, the total time-consuming to come into force is performed to power control commands and is less than 20MS.Therefore it can ensure that the speed of algorithm response is enough
Soon to keep up with the pace of change of wireless channel.
Step S218, end of calling.

To step S312.
Step S302, base station system parallel acquisition terminal report from antenna 0 to the forward power of antenna N-1 each of the links
Control bit.
Step S304, the power control bit finally gathered is analyzed compared with the power control bit of last time collection.
Step S306, if power control bit is power per liter instruction, this algorithmic decision is the transmission power of Jiang Gai roads antenna, if
Power control bit is drop power instruction, then this algorithmic decision is the transmission power of Sheng Gai roads antenna.
Step S308, the heave amplitude indicated according to the power control bit finally gathered, to determine the road antenna transmission power pair
The falling-rising amplitude answered.
Step S310, link control module corresponding to the road antenna is issued into the power control adjustment order of generation.
Step S312, after the link control module as corresponding to the antenna receives power control adjustment order, driving API is called to perform
The power control commands.
Algorithm mentioned by step S210 can also have other embodiments, such as be made with every frame forward emitting power of each of the links
