US 7,411,918 B2 · Dynamic radio link adaptation for interference in cellular systems

Abstract

A method for performing dynamic link adaptation by a user equipment (UE) in a cellular system, the UE having two coded composite transport channels (CCTrCHs) in an uplink time slot begins by estimating a transmit power for a first transport format combination (TFC) and a second TFC, each TFC corresponding to one CCTrCH. The estimated transmit power for the first TFC is compared with a maximum transmit power threshold of the UE, and is blocked if the estimated transmit power exceeds the threshold. The estimated transmit power for the second TFC is compared with the threshold, and is blocked if the estimated transmit power exceeds the threshold. The combined transmit power of the first TFC and the second TFC is compared with the threshold, and one TFC is selectively blocked if the combined transmit power exceeds the threshold, the blocking being based on a predetermined rule.
