ABSTRACT:
A dynamic link adaptation technique employed in a cellular system by a user equipment (UE) having two coded composite transport channels (CCTrCHs) in an uplink time slot begins by estimating transmit power using a transport format combination (TFC) pair for the CCTrCHs. The total estimated transmit power for two CCTrCHs is compared with a given threshold. The use of both TFCs is permitted when the total estimated power is less than the threshold. A power of each TFC is compared with the threshold and the TFC whose estimated power is greater than the threshold is blocked. A medium access control (MAC) is advised that one TFC is blocked, and the MAC notifies a codec associated with the TFC whose estimated power is less than that threshold to reduce the data rate when applicable.
