Referring to Fig. 1 a, for a kind of flow chart of an embodiment of uplink power control method of the present invention.This implementation
In example, the uplink power control method specifically includes step：
S101, the currently practical state of up-link is identified, if it is empty bag-like state, then execution step S103, no
Then, re-recognize.
Because in the prior art, terminal uplink data channel is sent generally along with the transmission of ascending control channel, and
And uplink data channels average duty ratio (dutycycle：Data are sent in the ratio in the business duration) it is very low, i.e., in business
In M TTI of duration, regardless of whether there is data transmission, the state of the up-link is in non-NULL bag-like state, i.e.,
SirTarget_DPCCH=SirTarget_RNC, it is upper that this necessarily make it that the up-link capacity of up empty bag data consumption exceedes
The 50% of row system total amount.However, before data are sent or after transmission, the up-link is that no data are sent in fact, i.e.,
Its virtual condition is to be in empty bag-like state.Therefore, in order to realize up-link power control, it is necessary to first work as to the up-link
Preceding virtual condition is identified, if it is empty bag-like state, then carries out empty bag processing, to reduce up transmission power.Specifically, should
Step S101 includes step：
