Abstract: A data transmission resource determining method includes determining an initial time interval and an interval difference, and determining, based on a initial time interval and a interval difference, a time domain position of a first time-frequency resource in response to the first TB being transmitted for an ith time, where i is a positive integer, and 2≤i≤Rmax+1. The initial time interval is between a time domain position at which a first transport block (TB) is transmitted for the first time and the second time. The interval difference is a difference between a first and a second time interval. The first time interval is between a corresponding time domain position at which the first TB is transmitted for a kth h time and (k+1)th time. The second time interval is between a corresponding time domain position at which the first TB is transmitted for the (k+1)th time and (k+2)th time.

Abstract: A third terminal receives control information from a first terminal, where the control information indicates a first resource and a second resource, the first resource carries first data corresponding to the control information, and the second resource is a sending resource reserved by the first terminal; the third terminal determines that the second resource meets a reselection condition; and the third terminal sends indication information to the first terminal, where the indication information indicates to reselect the second resource. When determining that a resource conflict exists in the second resource, the third terminal can indicate the first terminal in time to reselect the second resource, to prevent the first terminal from continuing to use the second resource to send data.

Abstract: This application relates to a resource selection method and an apparatus. A first resource is selected for first data from candidate resources in a resource pool. At least one resource is selected for the first data from the candidate resources other than the first resource based on the first resource and a first gap. A quantity of candidate resources is greater than or equal to X % of a quantity of all resources in the resource pool, where a value of X may be set based on a target quantity of resources, based on a target quantity of resources and a first time gap, based on a target quantity of resources, a first time gap, and a first frequency gap, or based on a service priority. The value of X may be set based on different factors, to meet a resource selection requirement.

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.
