Abstract: In a frequency domain resource configuration method, a terminal device receives from a first network device first configuration information for configuring a first frequency domain resource set. The first frequency domain resource set is to take effect after the terminal device is handed over from a source cell to a target cell. The terminal device receives handover indication signaling from the first network device to perform handover from the source cell to the target cell. The terminal device determines an activated frequency domain resource based on the first frequency domain resource set.

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 present disclosure discloses example random access resource configuration methods, mediums, and apparatuses. One example method includes receiving, by a first network device, configuration information of a first physical random access channel (PRACH) resource. Location adjustment information is received by the first network device, where the location adjustment information is used to indicate to adjust a location of at least a part of the first PRACH resource. A second PRACH resource is determined by the first network device based on the configuration information of the first PRACH resource and the location adjustment information. A random access request is sent by the first network device to a second network device on the second PRACH resource.

Abstract: Embodiments of this application disclose a resource configuration method and a communication apparatus. The resource configuration method includes: An integrated access and backhaul mobile terminal (IAB MT) determines a first time division duplex (TDD) configuration based on a first transmission mode. The first transmission mode includes a transmission mode on at least one frequency domain resource set in a plurality of frequency domain resource sets of an integrated access and backhaul distributed unit (IAB DU). The first TDD configuration is a cell-common TDD configuration or a dedicated TDD configuration. The IAB MT determines a resource location based on the first TDD configuration. It can be learned from the technical solution that the IAB MT selects the corresponding TDD configuration based on the transmission mode on the at least one frequency domain resource set, to determine the resource location.

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.
