Abstract: A sidelink control information sending and receiving method, a terminal apparatus, and a system are provided in this application, and may be applied to fields such as vehicle-to-everything (for example, V2X, LTE-V, or V2V), intelligent driving, and an intelligent connected vehicle. In a scenario in which second-stage SCI is not required in a sidelink communication system, a transmit end apparatus in sidelink communication indicates, by using first-stage SCI, a cyclic redundancy check bit corresponding to the first-stage SCI, or a reference signal used to demodulate the first-stage SCI, that the transmit end apparatus is not to send the second-stage SCI to a receive end apparatus. In this way, the transmit end apparatus may flexibly choose, based on a specific scenario of the sidelink communication, to use 2-stage SCI or 1-stage SCI, to avoid resource waste caused by using the 2-stage SCI in any scenario of the sidelink communication, thereby improving resource utilization efficiency.

Abstract: A first terminal apparatus sends K2 first reference signals to a second terminal apparatus in K1 directions. The first terminal apparatus determines that beams in the K1 directions all fail for N1 consecutive times. The first terminal apparatus sends P2 second reference signals to the second terminal apparatus in P1 directions. The first terminal apparatus determines, based on measurement results that are of the P2 second reference signals and that are from the second terminal apparatus, whether P1 beams corresponding to the P1 directions are available.

Abstract: This disclosure provides a communication method, apparatus, and system. In the method, a terminal apparatus that preempts a resource or may preempt a resource on an unlicensed spectrum performs avoidance in time for a terminal apparatus that reserves a resource, or shares a resource with a terminal apparatus that reserves a resource, so that the terminal apparatus that reserves the resource can send data in time. This meets a service requirement and significantly improves user experience.

Abstract: This application provides a method includes: If a first terminal device has to-be-sent periodic data, the first terminal device determines a first time unit set. The first terminal device determines that a first time unit in the first time unit set is used to send the periodic data, and determines, from the first time unit set based on a first time domain interval and a reservation quantity N, a second time unit set used to send the periodic data. A time domain interval between the 1st time unit in the second time unit set and the first time unit is the first time domain interval, and a number of a time unit in the second time unit set is greater than that of the first time unit. The method may be used in an internet of vehicles, for example, V2X, LTE-V, or V2V.
