Abstract: The disclosure provides example communication methods and apparatuses. One example method includes determining a highest-priority CORESET, so that a terminal device monitors a PDCCH on the highest-priority CORESET. A highest-priority CORESET is determined in M CORESETs belonging to T CORESETs based on one or more of cell identifiers, quasi co-location properties, search space set types, and search space set identifiers that are associated with the M CORESETs in a time unit, and a PDCCH is monitored on the highest-priority CORESET.

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.

Abstract: Embodiments of this application disclose a wireless communication method and an apparatus. The method includes: determining a target MCS if a current MCS exceeds a predetermined threshold, where the target MCS is an MCS less than or equal to the predetermined threshold; mapping a PTRS to one or more symbols based on the target MCS; and sending, to a terminal device, the symbol to which the PTRS is mapped. through implementation of the embodiments of this application, when the current MCS exceeds the predetermined threshold, the target MCS that is less than or equal to the predetermined threshold may be determined, so that a density of a PTRS on a time-frequency resource can be flexibly determined based on the target MCS and an association relationship between an MCS threshold and a time domain density of a PTRS, thereby helping reduce resource overheads of the PTRS.
