    摘要: This application provides an information transmission method and a communication apparatus, and relates to the communication field. A terminal device may indicate a first beam and a first moment by using first indication information, the terminal device measures at least one first reference signal based on second indication information, to obtain a second beam, and indicates the second beam by using third indication information, and the terminal device may receive first configuration information at a second moment. The second moment at which the terminal device receives the first configuration information is obtained based on the first moment. The first moment may be a future moment, that is, the terminal device may predict the first beam in advance. The second moment is not earlier than the first moment, and the second moment may also be a future moment. When the future second moment arrives, the terminal device may receive the first configuration information for configuring the second beam, so that a latency caused by determining the first beam after a beam failure can be avoided, to improve transmission reliability.

    摘要: Embodiments of this application disclose a beamforming weight calculation method, including: determining X sub resource block groups, where one of the X sub resource block groups includes a part of a resource block group, all resource block groups in each sub resource block group are occupied by a user, and X is a positive integer greater than 1; determining, based on the X sub resource block groups, a beamforming weight calculation method used for each sub resource block group, where the beamforming weight calculation method includes normalized-eigen beamforming or power limited-eigen beamforming; and obtaining, based on the beamforming weight calculation method corresponding to each sub resource block group, a beamforming weight corresponding to the sub resource block group. For each sub resource block group, a corresponding beamforming weight calculation method is adaptively determined, and a corresponding beamforming weight is obtained. This effectively improves a power utilization ratio of downlink data sending in a communications apparatus, effectively improves spectral efficiency of a cell, and improves an average throughput of the cell.

    摘要: A terminal according to one aspect of the present disclosure includes: a receiving section that receives one reference signal among a plurality of reference signals transmitted by using respective different resources; and a control section that controls reception of two or more reference signals among the plurality of reference signals, based on a result of reception of the one reference signal. The number of the plurality of reference signals is larger than 64. According to one aspect of the present disclosure, coverage can be improved in consideration of overhead.
