Abstract
The present disclosure relates to beam training methods and communication apparatuses. In one example method, a first UE sends first control information by using a first transmission beam, where the first control information includes resource location information of a first resource. Then, the first UE sends a first reference signal on the first resource by using M transmission beams, where M is a positive integer, the first transmission beam is different from each of the M transmission beams, and the first transmission beam covers each of the M transmission beams.
Claims20
A method, comprising:
- sending first control information by using a first transmission beam, wherein the first control information comprises resource location information of a first resource;
- and
- sending a first reference signal on the first resource by using M transmission beams, wherein M is a positive integer, the first transmission beam is different from each of the M transmission beams, and the first transmission beam covers each of the M transmission beams.
A method, comprising:
- sending a second reference signal on a second resource of a first time unit by using N transmission beams, wherein N is a positive integer;
- and
- sending a third signal on a third resource of the first time unit by using a fourth transmission beam, wherein the third signal is used by a user equipment (UE) that receives the second reference signal to perform automatic gain control (AGC), and the fourth transmission beam covers each of the N transmission beams.
A communication apparatus, comprising:

- sending a second reference signal on a second resource of a first time unit by using N transmission beams, wherein N is a positive integer;
- and
- sending a third signal on a third resource of the first time unit by using a fourth transmission beam, wherein the third signal is used by a user equipment (UE) that receives the second reference signal to perform automatic gain control (AGC), and the fourth transmission beam covers each of the N transmission beams.
A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program or instructions which, when executed by at least one processor, cause the at least one processors to perform operations comprising:
- sending first control information by using a first transmission beam, wherein the first control information comprises resource location information of a first resource;
- and
- sending a first reference signal on the first resource by using M transmission beams, wherein M is a positive integer, the first transmission beam is different from each of the M transmission beams, and the first transmission beam covers each of the M transmission beams.
