Abstract: A method for wireless communications at a user equipment includes determining whether high speed data has been scheduled by determining whether a scheduling channel has been enabled. The method also includes adjusting a clock speed based on a presence or an absence of the scheduling channel. The clock speed is adjusted without decoding the scheduling channel.

Abstract: A system and method reduce the frequency for performing measurements by a UE in a wireless network, such as a TD-SCDMA network. A UE compares at least one serving cell signal strength to a first threshold value. When the serving cell signal strength value is above the first threshold, the UE determines whether it is stationary. The UE determines whether it is stationary by evaluating change in serving cell signal strength and evaluating a timing difference value. The UE reduces the frequency for performing measurement(s) when changes in the serving cell signal strength values are below a second threshold value and the timing difference value is below a third threshold value. The timing difference can be a subframe number to subframe number (SFN-SFN) observed time difference.

Abstract: A method adaptively adjusts an internal clock rate and/or supply voltage based on an indication from a scheduling channel. A UE determines whether high speed data has been scheduled. The UE adjusts the clock speed and/or supply voltage based on the determination.
