Abstract

A communications method includes a first communications device that communicates a first signal on a first time domain resource in a first time unit, communicates a second signal on a third time domain resource in a second time unit, communicates a fourth signal on a second time domain resource in the first time unit, and communicates a third signal on a fourth time domain resource in the second time unit. The first time unit successively includes, in time domain, the first time domain resource, a first guard period, the second time domain resource, and a second guard period that are consecutive in time domain, and the second time unit successively includes, in time domain, the third time domain resource, a third guard period, the fourth time domain resource, and a fourth guard period that are consecutive in time domain.

Claims21

Dependent claims

A communications method implemented by a first communications device, wherein the communications method comprises:

communicating a first signal on a first time domain resource in a first time unit, wherein the first time unit successively comprises the first time domain resource, a first guard period, a second time domain resource, and a second guard period that are consecutive in a time domain, and wherein the first time domain resource comprises a first sub-time domain resource and a second sub-time domain resource located after the first sub-time domain resource in the time domain and adjacent to the first guard period;
communicating a second signal on a third time domain resource in a second time unit, wherein the first time unit and the second time unit comprise a same time length, wherein the second time unit successively comprises the third time domain resource, a third guard period, a fourth time domain resource, and a fourth guard period that are consecutive in the time domain;
communicating a fourth signal on the second time domain resource;
and
communicating a third signal on a on the fourth time domain resource.

2 more elements

A first communication device comprising:

a memory configured to store instructions;
and
a processor coupled to the memory and configured to execute the instructions to cause the first communication device to:
communicate a first signal on a first time domain resource in a first time unit, wherein the first time unit successively comprises the first time domain resource, a first guard period, a second time domain resource, and a second guard period that are consecutive in a time domain, and wherein the first time domain resource comprises a first sub-time domain resource and a second sub-time domain resource located after the first sub-time domain resource in the time domain and adjacent to the first guard period;
communicate a second signal on a third time domain resource in a second time unit, wherein the first time unit and the second time unit comprises a same time length, and wherein the second time unit successively comprises the third time domain resource, a third guard period, a fourth time domain resource, and a fourth guard period that are consecutive in the time domain;
communicate a fourth signal on the second time domain resource;
and
communicate a third signal on the fourth time domain resource.
