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 data transmission method and apparatus are applicable to fields such as V2X, intelligent driving, and connected vehicles. A probability of a collision between a high-priority PSSCH and a low-priority PSSCH is reduced, thereby improving QoS of the high-priority PSSCH. The method includes: obtaining resource pool configuration information including first resource pool information and second resource pool information, where the first resource pool information indicates a first resource pool, and the second resource pool information indicates a second resource pool; obtaining a first priority value corresponding to a physical sidelink shared channel PSSCH; when the first priority value is less than a first priority threshold, determining, in a partial-sensing-selection-based resource determination mechanism and/or a random-selection-based resource determination mechanism in the first resource pool, a resource for sending the PSSCH.

Abstract: This application relates to a communication method, an apparatus, and a system, and is applicable to fields such as Internet of Vehicles, intelligent driving, assisted driving, and intelligent connected vehicles. The method includes: determining a first time based on a first reference time and a first time offset, and sending, to a first terminal apparatus at the first time or before the first time, coordination information indicating a first resource, where the first resource is for determining a second resource for receiving sidelink information from the first terminal apparatus. Therefore, the time for sending the coordination information is limited. This ensures that the first terminal apparatus has sufficient time to determine, when the first terminal apparatus receives the coordination information, the second resource for sending the sidelink information, thereby improving reliability of sidelink communication.

Abstract: A method for determining a transport block size includes: determining an overhead of a sidelink data channel PSSCH demodulation reference signal (DMRS) in a physical resource block (PRB) of a first time-frequency resource, where the first time-frequency resource includes a first time unit in time domain; and determining, based on the overhead of the PSSCH DMRS, a number of resource elements (REs) on the first time-frequency resource that are for data transmission, where the number of REs for data transmission is for determining a transport block size (TBS) of the sidelink data channel PSSCH. The method provides a combined gain of a plurality of transmissions of a same transport block, and supports DMRS configurations of different quantities of DMRS symbols in initial transmission and retransmission of one transport block.

Abstract: A method for scheduling a terminal device comprises performing blind detection on N subframes by using at least one codebook and a pilot corresponding to the codebook, and determining, according to a blind detection result, a first pilot set corresponding to each codebook in each subframe, where correct terminal data cannot be obtained by performing blind detection by using a pilot in the first pilot set and a corresponding codebook. The method comprises determining, according to the first pilot set corresponding to each codebook, a second pilot set corresponding to each codebook, where a pilot in the second pilot set is a pilot that is in the first pilot set and that has already been sent by the terminal device, and determining a to-be-used transmission mode according to the second pilot set corresponding to each codebook in each subframe, where different transmission modes correspond to different spectrum multiplex rates.
