Abstract: This application discloses a method for sending a physical uplink shared channel and an apparatus and relates to the communication field, to resolve a problem of how to transmit uplink data to different TRPs by using different precoding matrices. A network device sends indication information to a terminal device, where the indication information is used to indicate first information and second information. The first information is used to indicate first precoding information corresponding to a first nominal PUSCH repetition. The second information is used to indicate second precoding information corresponding to a second nominal PUSCH repetition. The terminal device sends N PUSCHs based on precoding information indicated by the indication information. The precoding information corresponding to the N PUSCHs includes at least one of the first precoding information and the second precoding information.

Abstract: The present disclosure relates to communication methods and apparatus. In one example method, a terminal device receives first indication information, where the first indication information is used to indicate grouping information of N control resource sets in M control resource sets, N is less than M, and N and M are positive integers greater than or equal to 1. The terminal device determines grouping information of K control resource sets other than the N control resource sets in the M control resource sets based on the first indication information.

Abstract: A resource configuration method and a communications apparatus are disclosed. The method includes: After determining a first resource set that does not carry information bits included in any one of N codewords and a second resource set that does not carry information bits included in a part of the N codewords, a network device sends, to a terminal device, first information used to indicate configuration information of the first resource set and second information used to indicate configuration information of the second resource set. The terminal device receives the first information and the second information, and determines the first resource set and the second resource set. In the foregoing technical solution, a rate matching resource (the first resource set) common to the N codewords and a rate matching resource (the second resource set) dedicated to the part of the N codewords are configured.

Abstract: This application provides an example communication method and an example apparatus. The method includes a first network device generates first indication information to indicate a first downlink resource. Second indication information indicates a second downlink resource. Because the first indication information may indicate whether the second indication information exists, if a terminal device detects the first indication information in the first time unit, and the first indication information indicates that the second indication information does not exist in the first time unit, the terminal device may stop a blind detection process on the second indication information in advance.

Abstract: A communication method and apparatus are provided, to improve communication reliability. The method includes: When a first index of a first signal is the same as a first index corresponding to first indication information, a terminal device may communicate the first signal based on a first spatial parameter indicated by the first indication information. The first spatial parameter may be for communicating at least two types of signals/channels. For example, the first indication information may be a unified TCI. Therefore, according to the method, in a scenario in which a spatial parameter for a signal/channel is indicated by the unified TCI, a spatial parameter used for a to-be-sent signal/channel can be accurately determined, and the communication reliability can be improved.
