Abstract: This application communication methods and apparatuses. In an implementation, a communication method includes: A network device sends, to a first relay device, first information indicating a first time unit, a second time unit, and a first phase. The network device sends a first reference signal to a terminal device in the first time unit and the second time unit. The network device receives second information from the terminal device, where the second information indicates a first phase difference or a precoding matrix index (PMI) associated with the first reference signal, and the first phase difference or the PMI and the first phase are used to determine an association relationship between the first relay device and the terminal device.

Abstract: A power control method. The method includes: a communication apparatus determines a target forwarding power based on a first forwarding power, a second forwarding power, and a third forwarding power, and forwards, by using the target forwarding power, a first signal received from a first device to a second device. The target forwarding power is a lowest power of the first forwarding power, the second forwarding power, and the third forwarding power. The first forwarding power is determined based on an indication of a network device, the second forwarding power is related to an input power of the communication apparatus and a forwarding gain of the communication apparatus, and the third forwarding power is determined based on a maximum forwarding power limit of the communication apparatus.

Abstract: A method includes: receiving at least one synchronization signal/physical broadcast channel block (SSB) from a network device, forwarding the at least one SSB, and receiving an uplink access signal from a terminal on a first RO using a first spatial domain receiving parameter. Each of the at least one SSB has one index associated with a plurality of random access channel occasions (ROs). The first RO is one of the ROs associated with the index of each of the at least one SSB, the first spatial domain receiving parameter is determined based on a first spatial domain sending parameter to forward a first SSB, the first SSB is an SSB, in at least one second SSB, that is closest to the first RO in time domain, and each of the at least one second SSB is an SSB, in the at least one SSB, that satisfies a preset condition.

Abstract: 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.

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.
