Abstract: Embodiments of this disclosure provide a communication method and apparatus, a terminal device, a network device, and a medium. In the method, the terminal device receives first scheduling information from the network device, where the first scheduling information indicates a set of shared channel transmission occasions and a first beamforming manner of a shared channel. The terminal device receives second scheduling information from the network device, where the second scheduling information indicates a control channel transmission occasion and/or a second beamforming manner of a control channel. If the terminal device determines that time domain resources of the control channel transmission occasion and one or more shared channel transmission occasions in the set of shared channel transmission occasions at least partially overlap, the terminal device determines at least one shared channel transmission occasion from the set based on at least one of the first beamforming manner and the second beamforming manner.

Abstract: This disclosure provides a communication method and a network controlled repeater (NCR), and relates to the communication field. The NCR includes KN donor antenna ports and KN service antenna ports. The method includes: The NCR performs uplink forwarding in any one of K time unit sets by using N service antenna ports and N donor antenna ports, where the N service antenna ports and the N donor antenna ports are respectively a part of the KN service antenna ports and a part of the KN donor antenna ports; and in any two of the K time unit sets, the NCR uses different donor antenna ports and different service antenna ports. In this disclosure, downlink CSI with relatively high accuracy can be obtained when a quantity of uplink forwarding channels and a quantity of downlink forwarding channels of the NCR are different.
