A method includes receiving a Code Division Multiple Access (CDMA) carrier carrying at least a pilot channel. Differences are computed between selected soft pilot symbols received on the pilot channel. Based on the computed differences between the selected soft pilot symbols received on the pilot channel, a level of noise is estimated for a data channel that is to be transmitted on the CDMA carrier.

Data channel noise estimation using pilot channel

A method includes receiving a Code-Division Multiple Access (CDMA) signal carrying at least a data channel, a pilot channel and a control channel. A first noise level is estimated on the pilot channel. A second noise level is estimated on the control channel. The first estimated noise level and the second estimated noise level are combined to produce a noise estimate of noise on the data channel.

Data channel noise estimation using control channel

Aspects of the disclosure provide a wireless user equipment that can receive and demodulate a paging indicator with a reduced time duration. Therefore, the wireless user equipment may have a reduced wake-up time. The wireless user equipment can include a receiving module configured to receive signal components including a first signal transmitted over a common pilot channel (CPICH) and a second signal transmitted over a paging indicator channel (PICH) during a time duration. The second signal can include a paging indicator in the time duration. Further, the wireless user equipment can include a processor module configured to select a plurality of correlations in the second signal received during the time duration based on correlations in the first signal received during the time duration, and to extract the paging indicator from the plurality of correlations in the second signal. Additionally, the wireless user equipment can include a controller module configured to control the wireless user equipment according to the paging indicator.

Method and apparatus for wireless receiving

Briefly, a wireless communication device, a wireless communication system and a method of controlling a transmission power level of a dedicated channel signal transmitted in a compress mode with an alternate scrambling code. The method includes transmitting one or more power control commands to a base station to control a transmission power of one or more frames scrambled by primary scrambling codes and prior of receiving a dedicated channel signal scrambled by alternate scrambling codes, transmitting one or more pre-alternate scrambling codes power control commands.
