摘要： Embodiments of this application provide a device-to-device based resource determining method and device, which may be applied to a D2D system (for example, a system such as an internet of vehicles, V2X, or V2V). The method includes: receiving first information sent by a first terminal device, where the first information indicates a second terminal device to send assistance information; and sending the assistance information to the first terminal device, where the assistance information is used to assist the first terminal device in selecting a resource for data transmission. The second terminal device assists the first terminal device in determining the resource for data transmission, instead of completely determining, by a terminal device that sends data, the resource for data transmission.

摘要： A communication method and apparatus are disclosed. A first terminal apparatus may receive first data from a second terminal apparatus, and determine a feedback time unit in a channel occupancy time, where the feedback time unit corresponds to the first data. The first terminal apparatus may transmit first feedback information on a first frequency domain resource in the feedback time unit, and transmit second feedback information on a second frequency domain resource. The first feedback information is an acknowledgment or a negative acknowledgment for the first data, the first frequency domain resource is determined based on a time-frequency resource carrying the first data, the first frequency domain resource and the second frequency domain resource belong to a first channel, and the first frequency domain resource and the second frequency domain resource do not overlap.

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： 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.

摘要： This application may be applied to an internet of vehicles, for example, V2X and LTE-V. A first terminal apparatus determines, a first resource pool. The first terminal apparatus detects control information of a second terminal apparatus, where the control information indicates second service data of the second terminal apparatus, and the control information includes location information of the second terminal apparatus, a first frequency domain resource, and a periodicity of the second service data. The first terminal apparatus determines an unavailable time-frequency resource in the first resource pool based on location information of the first terminal apparatus, the location information of the second terminal apparatus, a first threshold, the first frequency domain resource, and the periodicity of the second service data. The first terminal apparatus selects a first time-frequency resource from available time-frequency resources in the first resource pool to transmit first service data.

摘要： 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.
