Abstract

A method for adaptively adjusting power margin over a forward control channel PDCCH from a base station BS to a mobile station MS during a call. Corresponding message packets are sent in parallel over PDCCH and a data channel PDCH to an MS. The BS monitors a reverse channel ACKCH for an expected reply from the MS. If the reply is ACK, the power margin for the next subsequent transmission on PDCCH is lowered. If the reply is NACK, the power margin for the next subsequent transmission on PDCCH is lowered. If no reply is timely received, the power margin for the next subsequent transmission on PDCCH is raised. If the method is applied also to PDCH, an ACK reply causes the power margin on PDCH to decrease; a NACK reply causes the power margin on PDCH to increase, and no reply leaves the power margin on PDCH unchanged.
