Abstract: This application provides a method for reporting a measurement result of interference measurement, to implement interference management performed by a parent node on a child node in an IAB system. The method includes: performing, by a second node, interference measurement to obtain one or more measurement results, the interference measurement includes interference measurement in a first mode and/or interference measurement in a second mode, and sending, by the second node, an uplink signal to the first node, the uplink signal includes the one or more measurement results, the uplink signal includes an indication field, and the indication field is used to indicate a mode of interference measurement corresponding to each of the one or more measurement results.

Abstract: This application provides a resource configuration method and apparatus. A multiplexing type between a second functional unit and each of one or more antenna panels of a first functional unit is indicated to an IAB node, so that the IAB node obtains a resource configuration of an MT or a resource configuration of a DU based on the multiplexing type. This helps implement a resource configuration in the IAB node in a case of a plurality of antenna panels.

Abstract: This application provides a data transmission method and apparatus, to reduce wastes of transmission resources. The method includes: receiving, by a first node, a data packet from an air interface, where the first node is a wireless backhaul node, and the wireless backhaul node is configured to provide a wireless backhaul service for a node that wirelessly accesses the wireless backhaul node; duplicating, by the first node, the data packet to obtain M data packets, where M is an integer greater than 1; and splitting, by the first node, the M data packets, and sending the M data packets to a second node through at least two paths. This application relates to the field of communications technologies.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.

Abstract: A resource multiplexing method and apparatus are provided, to determine a set of available symbols in an NR IAB system. A first node determines a time domain position of a DU resource of a communications device, and determines a time domain position of an MT resource of the communications device based on the time domain position and a type of the DU resource and guard interval information. Alternatively, a first node determines a time domain position of an MT resource of a communications device, and determines a time domain position of a DU resource of the communications device based on the time domain position and a type of the MT resource and guard interval information.

Abstract: This application discloses a communication method and an apparatus. When a terminal device switches to a target cell or is connected to a new primary cell, by requesting a network device to release a session corresponding to a network slice that is not supported by the target cell or the new primary cell and to keep a session corresponding to a network slice that is supported by the target cell or the new primary cell, the session corresponding to the network slice that is not supported by the target cell or the new primary cell can be quickly released, and a network resource is saved while a session corresponding to a network slice supported by the target cell or the new primary cell is enabled to be continued.
