摘要： This application provides a communication method and a terminal device, and relates to the communication field. The method includes: A subband non-overlapping full-duplex device obtains first information, where the first information indicates a first time-frequency resource occupied by a first data channel in a first frequency band and a second time-frequency resource occupied by a first feedback channel in a second frequency band; determines a mapping relationship between a third time-frequency resource and a fourth time-frequency resource based on the first information and an identifier of the device, where the third time-frequency resource is a part or all of the first time-frequency resource, and the fourth time-frequency resource is a part or all of the second time-frequency resource; sends the first data channel on the third time-frequency resource; and receives the first feedback channel on the fourth time-frequency resource. In this manner, the subband non-overlapping full-duplex device can determine a mapping relationship between the data channel and the feedback channel based on the first information, to prevent the device from simultaneously receiving/sending a feedback channel in a same frequency band. This can ensure communication reliability.

摘要： This application provides a communication method and apparatus. The method includes: A first device receives a control channel and a first data channel, where the first device receives the control channel and the first data channel based on a same spatial domain receive parameter, or the first device receives both the control channel and the first data channel through an omnidirectional beam, and indication information of a spatial domain receive parameter of a second data channel is carried on the control channel and/or the first data channel. The first device receives the second data channel based on the indication information. In this application, the first device may first determine the spatial domain receive parameter of the second data channel based on the indication information of the spatial domain receive parameter of the second data channel in the control channel or the first data channel. Therefore, when the second data channel is being received, the determined spatial domain receive parameter may be used, thereby improving receiving performance of the data channel.

摘要： Embodiments of this application provide a resource selection method and apparatus, and relate to the communication field, to reduce a collision between reserved resources of terminal devices and subsequent resource reselection, thereby improving communication efficiency. The method includes: A first terminal device determines an initial candidate resource set including M resources, and determines, based on an RSRP and a collision index that are associated with SCI received in a sensing window, whether to exclude an i th resource in the M resources from the initial candidate resource set, to obtain a candidate available resource set. The collision index is an index of a collision between a reserved resource indicated by the SCI received in the sensing window and an i th periodic resource. The i th periodic resource includes the i th resource and a resource obtained after the i th resource is extended based on a preset first period. Herein, M is a positive integer, and i is a positive integer from 1 to M.

摘要： This application provides a resource selection method and apparatus. The method includes: A first terminal device receives first indication information from a second terminal device, where the first indication information indicates quality of SL transmission between the first terminal device and the second terminal device on a first resource, and the first resource is a resource indicated by a third terminal device (S310); and the first terminal device determines that a quantity of times the first indication information meets a preset condition is greater than or equal to a preset value, and selects a second resource, where the second resource is different from the first resource (S320). According to the technical solution of this application, the preset condition is set, and resource selection is performed when link interference is large, to help improve an anti-interference capability of a communication system; and when the first resource indicated by the third terminal device can meet the quality of the SL transmission between the first terminal device and the second terminal device, there is no need to perform resource selection, which reduces energy consumption overheads.

摘要： This application provides a synchronization method and a communication apparatus. The method includes: A first terminal uses another terminal as a candidate synchronization reference source with a highest synchronization priority. Because it is easy to deploy a terminal as a synchronization source, the first terminal can be easily synchronized to a terminal, and does not need to continuously search for another synchronization source after synchronization. Therefore, power consumption of searching for a synchronization source by the terminal can be reduced. Compared with a method in which a GNSS is preferentially used as a synchronization source or a base station is preferentially used as a synchronization source, a synchronization method of a first synchronization type provided in embodiments of this application can achieve synchronization more quickly, and power consumption overheads caused by continuous searching for a synchronization source can be reduced.
