TECHNIQUES AND APPARATUSES FOR WAVEFORM SIGNALING FOR DOWNLINK COMMUNICATIONS
First Claim
1. A method of wireless communication, comprising:
- receiving, by a user equipment (UE), a waveform indication in a first downlink channel that uses a first waveform of a plurality of waveforms;
determining, by the UE, a second waveform, of the plurality of waveforms, to be used for one or more downlink communications in a second downlink channel based at least in part on the waveform indication received in the first downlink channel; and
processing, by the UE, the one or more downlink communications received in the second downlink channel using the second waveform.

Abstract
When a base station is capable of using multiple different types of waveforms for a downlink communication to a UE, the UE may waste processing resources attempting to receive and/or process the downlink communication. For example, the UE may cycle through various possible types of waveforms in an attempt to process the downlink communication. Techniques described herein use waveform signaling for downlink communications to notify the UE of a type of waveform being used for a downlink communication, thereby conserving UE resources (e.g., processing resources, memory resources, RF resources, and/or the like) that would otherwise be wasted attempting to process the downlink communication using multiple types of waveforms.
