    Abstract: The communication method and the communications apparatus may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: A first terminal apparatus determines a scaling factor based on a subcarrier spacing of a first time-frequency resource to be used to send first data and/or a quantity of slots occupied by the first time-frequency resource. The first data is to-be-sent data of the first terminal apparatus, and the first time-frequency resource occupies a single slot or a plurality of consecutive slots. Then, the first terminal apparatus determines, based on the scaling factor, a size of a transmission block carrying the first data, and sends the transmission block carrying the first data to a second terminal apparatus on the first time-frequency resource.

    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.

    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.
