The method includes: determining a first resource in a first slot and a second resource in a second slot, where the first resource and the second resource are used to send data; and sending resource indication information in a third slot, where a value of the resource indication information is used to indicate a frequency domain position of the first resource and a frequency domain position of the second resource, and the second slot and the first slot are later than the third slot.

Resource indication method, resource determining method, and apparatus

This application relates to the field of communication technologies, especially to V2X, intelligent driving, intelligent and connected vehicles, and the like. The method includes: sending, by a first terminal, first information to a second terminal, where the first information includes information indicating a feedback manner of first data, the first data is a data packet sent by the first terminal to the second terminal, the feedback manner is a first feedback manner or a second feedback manner, the first feedback manner is that the second terminal feeds back, to the first terminal, only acknowledgement information indicating that the data packet fails to be received, and the second feedback manner is that the second terminal feeds back, to the first terminal, acknowledgement information indicating that the data packet is successfully received or fails to be received. The method is applied to a multicast transmission process.

Multicast feedback configuration method and apparatus

A resource indication method, a resource determining method and a related apparatus that indicate transmission resources in two subframes are provided, which relate to the field of wireless communications technologies. The method includes a transmitting device determining first and second time domain resources and sending resource indication information on a third time domain resource, wherein the resource indication information indicates positions of the first and second time domain resources, and wherein a value of the resource indication information is determined by using the positions of the first and second time domain resources.

Resource indication method, resource determining method, and related apparatus

This application provides a sidelink channel state information transmission method and a communication apparatus. The method and the apparatus may be applied to systems such as an internet of vehicles, V2X, and V2V. The method includes: a first terminal device sends modulation and coding scheme (MCS) table indication information, wherein the MCS table indication information indicates a MCS table corresponding to data sent by the first terminal device to a second terminal device, and the MCS table is associated with a resource pool for sending the data.

Sidelink channel state information transmission method and communication apparatus

This application provides a communication method, and a distance determining method and apparatus. A first terminal device sends a first signal. A second terminal device determines whether a location of the second terminal device is a specified area. When the location of the second terminal device is the specified area, the second terminal device sends feedback information. When the location of the second terminal device is not the specified area, the second terminal device does not send feedback information or sends less feedback information. This method is applicable to communication, for example, V2X communication or D2D communication, between terminal devices on a sidelink.

Communication method, and distance determining method and apparatus

This application provides a communication method and a communications apparatus. The communication method includes: a first terminal device determines a first parameter, where the first parameter is used to indicate a parameter of a sensing window, a parameter of a resource selection window, and/or a parameter of a first time window, and the first time window includes the sensing window and the resource selection window. The first terminal device determines a first resource pool from at least one resource pool based on the first parameter. The first terminal device selects a first resource from the first resource pool. The first terminal device transmits sidelink information on the first resource. According to the method provided in embodiments of this application, a data transmission delay can be reduced and system communication efficiency can be improved.
