Abstract
Method and apparatus for processing transmit power control (TPC) commands in a wideband CDMA (WCDMA) network based on a sign metric are disclosed and may include calculating a sign metric of a downlink dedicated physical channel (DPCH) based on a plurality of TPC bits received via the downlink DPCH. A value of at least one of the plurality of TPC bits may not be known when the at least one of the plurality of TPC bits is received. The sign metric may specify an error associated with the plurality of TPC bits. Transmit power may be adjusted for a signal transmitted via at least one uplink communication channel based on the calculated sign metric. At least one reliability weight value may be calculated for at least a portion of the received TCP bits, based on the calculated sign metric.
