Title:
TECHNIQUES AND APPARATUSES FOR IMPROVING EFFICIENCY OF POWER TRACKING IN USER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/157271
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine one or more power tracking parameters for a plurality of uplink carriers based on at least one of respective PAPRs of the plurality of uplink carriers, or respective drive power biases for amplifying the plurality of uplink carriers; and/or configuring, by the user equipment, respective drive powers of a plurality of power amplifiers of the user equipment to amplify respective signals of the plurality of uplink carriers based at least in part on the one or more power tracking parameters, wherein configuring includes configuring, by employing a same power tracking component, respective drive powers of at least two of the plurality of power amplifiers of the user equipment to amplify corresponding signals of the at least two uplink carriers. Numerous other aspects are provided.
