Abstract: This application provides a method for determining a receive parameter used for channel measurement, including: receiving measurement configuration information, where the measurement configuration information includes configuration information of at least one resource; and if any one or more of the following conditions are met, determining that the at least one resource and n resources have a same receive beam, where the n resources are n resources that can be simultaneously received, and n≥2; the condition includes: the at least one resource has a same transmission configuration index (TCI) configuration as one of the n resources; the at least one resource has a same TCI configuration as one of the n resources, and a parameter groupBasedBeamReporting is further configured in the measurement configuration information; or the at least one resource has a same TCI configuration as one of the n resources, and a value of a configured parameter groupBasedBeamReporting is enabled.

Abstract: Example communications methods and apparatus are described. One example method includes generating a first signal by a base station. The base station performs cyclic delay diversity (CDD) weighted processing on the first signal to obtain a second signal, and performs densified beam weighted processing on the second signal to obtain a third signal. The third signal is sent by the base station via an antenna. According to the foregoing method, the CDD weighted processing is performed on the first signal generated by the base station, so that time diversity can be obtained when the first signal is transmitted. In addition, the densified beam weighted processing is performed on the second signal obtained after the CDD weighted processing, so that a quantity of beams scanned by the base station can be increased.
