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.
