ABSTRACT:
Method and apparatus for improving a noise power estimate in a wideband CDMA (WCDMA) network are disclosed and may include calculating a total noise power estimate for a downlink channel based on a plurality of control channel bits from a plurality of different types of control channels. The plurality of control channel bits may include at least two of: dedicated physical channel (DPCH) transmit power control (TPC) bits, DPCH pilot bits, and common pilot channel (CPICH) bits. A first noise power estimate may be calculated for the downlink channel based on a plurality of the DPCH TPC bits. A value of at least one of the plurality of DPCH TPC bits may not be known when the at least one of the plurality of DPCH TPC bits is received.
