Abstract: A reference signal transmission method is disclosed, the method including: determining at least two first reference signal resources; receiving a first channel based on the at least two first reference signal resources when a scheduling offset is less than or equal to a preset threshold and/or there is no spatial relation parameter information indication field in downlink control information DCI; and demodulating the first channel. When data on at least two reference signal resources needs to be received within a period of time, the method can increase a probability that a terminal device successfully receives the data.

Abstract: Embodiments of the present invention disclose a communication method and a device. Configuration information indicating one or more spatial domain beam basis vector groups and Q thresholds is received from a network device, where the Q thresholds correspond one-to-one to spatial domain beam basis vectors in the one or more spatial domain beam basis vector groups. L spatial domain beam basis vectors are selected from a spatial domain beam basis vector group set. K frequency domain basis vectors are selected from a frequency domain basis vector set for each of the L spatial domain beam basis vectors.

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 a communications apparatus are provided. The method includes: determining a first bandwidth part (BWP) and a second BWP; determining an association relationship between the first BWP and the second BWP; and recovering a link of a first downlink resource of the first BWP based on the association relationship and/or detecting a link failure of a second downlink resource of the second BWP based on the association relationship. The link of the first downlink resource of the first BWP can be accurately recovered based on the association relationship between the two BWPs, thereby ensuring communication reliability.
