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.
