Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a device may determine a peak to average ratio (PAR) value for a portion of a wireless transmission. In some aspects, the device may cause, based on the PAR value, a voltage to be applied to a power amplifier of the device to cause the device to transmit the portion of the wireless transmission.

Techniques and apparatuses for peak to average ratio (PAR) based power management

A wireless communication device includes: a first communications unit configured to communicate with a first communication network; a second communications unit configured to communicate with a second communication network; a control unit configured to control operation of the wireless communication device; and one or more temperature sensors configured to sense operating temperatures of the first communications unit and the second communications unit and provide temperature signals to the control unit. In response to a determination that an operating temperature of the first communications unit conducting a first call exceeds a predetermined threshold temperature and an operating temperature of the second communications unit does not exceed the predetermined threshold temperature, the control unit is configured to cause the first call on the first communications unit to be switched from a first transceiver chain in the first communications unit to a second transceiver chain in the second communications unit.

Methods and apparatus for wireless communication, in a mobile device, that includes receiving a signal from a network and obtaining pruned autocorrelation for specific channel delays of the received signal. Aspects of the methods and apparatus include determining pruned autocorrelation properties of the received signal. Aspects of the methods and apparatus also include comparing the pruned autocorrelation properties of the received signal against a reference threshold. Aspects of the methods and apparatus also include verifying that the received signal is a valid signal for WCMDA processing.
