US 12,302,300 B2 · Waveform selection in wireless communications

Abstract

Techniques are described that provide for waveform selection for uplink (UL) and/or downlink (DL) wireless transmissions based on one or more factors associated with the wireless transmission, a transmitter that is to transmit the wireless transmission, or combinations thereof. UL and DL transmissions may use one of a number of different waveforms, such as single-carrier waveforms that use a single carrier for information transmission of a wireless channel, and multi-carrier waveforms that use multiple carriers at different frequencies to transmit some of the bits on each channel. Multi-carrier transmission waveforms or single-carrier waveforms may be selected for wireless transmissions based on a bandwidth allocated for the transmissions, a capability of a transmitter that is to transmit the transmissions, or combinations thereof.

Dependent claims

A method for wireless communication at a base station, comprising:

receiving a radio frequency (RF) capability indication from a user equipment (UE), wherein the RF capability indication comprises a capability of the UE to support a waveform and to transmit over an allocated bandwidth and wherein the RF capability indication indicates a single-carrier bandwidth capability of the UE;
selecting a multi-carrier waveform from among a single-carrier waveform and the multi-carrier waveform for a wireless transmission based at least in part on a bandwidth for the wireless transmission exceeding the single-carrier bandwidth capability of the UE;
transmitting, to the UE, an indication of the multi-carrier waveform and the bandwidth for the wireless transmission, wherein the waveform and the bandwidth are based at least in part on the capability of the UE to support the waveform and to transmit over the allocated bandwidth;
and
performing the wireless transmission using the bandwidth.

2 more elements

An apparatus for wireless communication, comprising:

one or more processors;
one or more memories coupled with the one or more processors;
and
