摘要： This application provides a beam determining method and an electronic device, and relates to the communication field. In the method, if a first terminal device detects, on a first target resource, a first sequence bound to the first terminal device, the first terminal device determines that a beam for sending a first reference signal corresponding to the first target resource is a first target beam. The first terminal device does not distinguish a device that sends the first sequence. If a plurality of different devices send first sequences on the first target resource, a gain of receiving the first sequences can be improved, so that the first sequences do not fail to be received. Therefore, the devices that send the first sequences do not need to wait. This can reduce a delay.

摘要： This application provides a beam training method in sidelink and an apparatus, to implement collaboration between a first device and a second device in a beam training process. The method includes: A first device sends N pieces of first control information to a second device respectively in N time units. The first control information includes first indication information. The first indication information indicates a time interval between a time unit associated with the first control information and a time unit associated with a last piece of first control information. The first device receives a measurement result reported by the second device. The measurement result includes second indication information. The second indication information indicates identifiers of one or more reference signals in reference signals associated with M pieces of first control information. The N pieces of first control information include the M pieces of first control information. N is a positive integer, and M is a positive integer less than or equal to N.
