Abstract

This disclosure relates to techniques for opportunistically depowering receiver chains of a wireless device. Based on received control information, a device may determine a depowering time. For example, the device may determine a minimum number of symbols of the payload channel that will provide an effective spectral efficiency less than a supportable spectral efficiency of the payload channel. The depowering time may be determined as a time upon receipt of the determined minimum number of symbols. The device may determine whether to perform a depowering procedure, based upon the determined depowering time. In response to determining to perform the depowering procedure, the device may depower an RF receiver of the device at the depowering time, wherein the depowering time is prior to the end of the payload channel. The device may decode the payload channel based on a portion of the payload channel received by the RF receiver.

Dependent claims

A user equipment device (UE) comprising:

radio frequency (RF) receiver circuitry configured to receive a wireless communication subframe;
and
processing circuitry coupled to the RF receiver circuitry, the processing circuitry configured to cause the UE to:
receive control information indicating that the subframe comprises a payload channel for the UE;
determine a depowering time based on the control information, wherein the depowering time is prior to the end of the payload channel;
determine whether to perform a depowering procedure, based at least in part upon the determined depowering time;
in response to determining to perform the depowering procedure, depower the RF receiver circuitry at the depowering time;
in response to determining not to perform the depowering procedure, maintain the RF receiver circuitry in a full-power state at least until the end of the payload channel;
and
decode the payload channel based on a portion of the payload channel received by the RF receiver circuitry.
