OUTER LOOP POWER CONTROL METHOD AND DEVICE

摘要

A method and an apparatus for controlling outer loop power are provided by the present invention. The method comprises the steps as follows: a BLER acquisition unit obtains a BLER of received data by carrying out decoding and a cyclic redundancy check on the data (S101); a bit error rate acquisition unit obtains a BER of a dedicated physical control channel by judging a pilot signal (S102); it is judged that whether or not the BLER of the data is greater than a BLERtarget and a first adjustment on the SIRtarget is carried out according to the judgment result(S 103); and if values of n consecutive BERs are smaller than or equal to a Bit Error Rate target value (BERtarget), then a second adjustment is carried out, wherein n is a positive integer (S 104). A method for accelerating the convergence of SIR is provided by the present invention with the premise of ensuring the quality of services, which not only can ensure the minimum signal to interference ratio required by the services but also can accelerate the convergence speed of the SIR.
