Abstract: In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.

Abstract: A wireless communication system and method for controlling transmission power to maintain a received signal-to-interference ratio (SIR) as close as possible to a target SIR. A received quality is maintained as close as possible to a target quality based on block error rate (BLER). When a target BLER is converted to an initial target SIR, an error may occur due to a channel condition mismatch, since the target SIR required for the target BLER varies with channel conditions. An outer loop power control process is used to set a target SIR for each coded composite transport channel (CCTrCH) based on the required target BLER. The process adjusts a SIR step size parameter to maximize the convergence speed of the process.
