Abstract: Embodiments of this application disclose a communication method and a communication apparatus. The method in embodiments of this application includes: A terminal device performs first-type measurement on a first reference signal, to obtain a first measurement result. The terminal device sends the first measurement result to a network device. The terminal device performs second-type measurement on a second reference signal based on the first measurement result, to obtain a second measurement result. The terminal device sends the second measurement result to the network device. It can be learned that, according to the foregoing technical solution, the terminal device reports the second measurement result to the network device, and the network device does not need to trigger, by using downlink control information, the terminal device to report the measurement result, so that signaling overheads and latency overheads are reduced.

Abstract: This application discloses a channel measurement method and apparatus. A network device sends downlink signaling, to indicate or activate a beam. A terminal device determines the beam indicated or activated by using the downlink signaling, determines, based on an association relationship between a beam and a channel measurement configuration, a channel measurement configuration associated with the beam, performs channel measurement based on the channel measurement configuration, to obtain a channel measurement result, and reports the channel measurement result to the network device. According to the channel measurement solution in this application, when channel quality of a new beam needs to be measured, the network device does not need dedicated signaling to indicate a channel measurement configuration associated with the new beam. When the beam is indicated or activated, the terminal device is triggered to perform channel measurement, to implement low-latency and low-overhead channel measurement.
