Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a phase tracking reference signal. The phase tracking reference signal is transmitted using a single carrier waveform and encoded within a time domain. Accordingly, the UE may decode, from the base station, a message, based at least in part on the phase tracking reference signal. Numerous other aspects are provided.
Claims28
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a base station, a phase tracking reference signal,
- wherein the phase tracking reference signal was transmitted using a single carrier waveform and encoded within a time domain;
- and
- decoding a message, received from the base station, based at least in part on the phase tracking reference signal,
- wherein the phase tracking reference signal is based at least in part on a sequence with zero mean and a low cross-correlation property.
A method of wireless communication performed by a base station, comprising:
- determining a phase tracking reference signal for a single carrier and within a time domain;
- and
- transmitting, on the single carrier and to a user equipment (UE), the phase tracking reference signal,
- wherein the phase tracking reference signal is based at least in part on a sequence with zero mean and a low cross-correlation property.
An apparatus for wireless communication at a user equipment (UE), comprising memory, and one or more processors coupled to the memory and configured to:
- receive, from a base station, a phase tracking reference signal,
- wherein the phase tracking reference signal was transmitted using a single carrier waveform and encoded within a time domain;
- and
- decode a message, received from the base station, based at least in part on the phase tracking reference signal,
- wherein the phase tracking reference signal is based at least in part on a sequence with zero mean and a low cross-correlation property.
