摘要： This application provides a method and an apparatus for determining a sidelink transmission resource, and may be applied to systems such as the Internet of vehicles, V2X, and V2V. The method includes: determining a first time domain resource set in a resource selection window; monitoring a second time domain resource set corresponding to the first time domain resource set; and performing resource exclusion and/or resource reporting before a time unit of a first candidate resource, or in the time unit of the first candidate resource, or in a time unit in which resource determining is triggered, where the first time domain resource set is for sidelink transmission, and the first candidate resource is the 1st resource in time domain in the first time domain resource set.

摘要： 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.

摘要： A method includes: determining, in a time unit n based on at least two resource reservation period parameters {P′1, P′2, . . . , P′T}, a sensing time unit set corresponding to a candidate time unit ty, where the candidate time unit ty is located in a resource selection window after the time unit n, and the sensing time unit set is located before the time unit n; and excluding, based on a sensing result in the sensing time unit set, an unavailable candidate resource unit in the candidate time unit ty.
