Abstract: Embodiments of the present invention provide a method for releasing a semi-persistent scheduling resource and a device. The method can be used in V2X communication. The method may include receiving, by a base station, service information sent by user equipment UE. The service information may include first service information of first service data. The method may further include determining, by the base station based on the first service information, semi-persistent scheduling SPS information corresponding to the first service data; and sending, by the base station, downlink control information DCI to the UE. The DCI may include the SPS information, and may be used to instruct the UE to activate the new SPS resource and release a target SPS resource. The target SPS resource may include an SPS resource corresponding to second service data that has been transmitted. This can reduce signaling overheads of the DCI.

Abstract: A communication method and a communications apparatus are disclosed. In the communication method, a first terminal obtains a resource period parameter, where the resource period parameter is sent by a network-side device or preconfigured by the first terminal. The resource period parameter includes a period duration of each of at least one resource. The first terminal determines a start time unit of a resource period, and the first terminal sends communication data according to the start time unit of the resource period and the resource period parameter.

Abstract: This application discloses a tag positioning method. In this application, a target tag receives first signaling sent by a target reader/writer, where the first signaling includes an identity ID of a first transmitter. The target tag sends second signaling to the target reader/writer, where the second signaling includes the ID of the first transmitter. Further, the target reader/writer may determine, based on the ID that is of the first transmitter and that is included in the signaling sent by the target tag, a coverage area that is of a transmitter and in which the target tag is located, to more accurately determine a location of the tag. Therefore, efficiency of tag positioning is improved.

Abstract: Embodiments provide user equipment includes a processor and a transmitter. The processor determines a time domain resource within a T2 time length based on second time domain resource indication information, where the second time domain resource indication information indicates a time domain resource occupied for data transmission within a T1 time length, and T2 is twice of T1. The processor further generates second control information, where the second control information includes the second time domain resource indication information. The transmitter sends the second control information. The transmitter further sends data on the time domain resource that is determined within the T2 time length. In this way, only a time domain pattern with a half time length of a period is defined, so that total time domain patterns in a system are applicable to a vehicle-to-vehicle communication scenario. In addition, time domain resource indication information occupies fewer bits, thereby saving system resources.
