Abstract: A communication method and an apparatus. A first node receives a first message from a second node. The first message indicates a first ratio corresponding to a first downlink reference signal. The first ratio is a power ratio that is between data and a downlink reference signal and is obtained after downlink transmission power adjustment is performed by a parent node. The first node sends a second message to the parent node. The second message includes a first measurement result. The first measurement result is determined based on the first ratio, and the first measurement result is determined based on the first downlink reference signal.

Abstract: A communication method and apparatus to enable uplink transmission of a terminal to be synchronized with a plurality of stations corresponding to one cell, and avoid a performance loss of uplink transmission. The terminal receives configuration information from a network device, wherein the configuration information includes two timing advance groups (TAGs) corresponding to one cell, and each TAG corresponds to one timing advance (TA). The terminal receives a plurality of random access response messages from the network device, wherein each random access response message is usable to indicate a TA corresponding to one of the two TAGs.

Abstract: A cell handover method and an apparatus. Indication information is received from a source cell, where the indication information indicates to a first transmission configuration indicator TCI state and cell handover; initiating random access to a target cell according to the indication information. In response to first response information returned by the target cell being received, second response information is returned to the source cell, where the second response information indicates that the first TCI state is successfully activated. Cell handover is implemented through beam switch to reduce a delay of a terminal device during the cell handover. The terminal device returns the second response information to the source cell only after receiving the first response information returned by the target cell.

Abstract: Data transmission methods and apparatuses for wireless backhaul networks are described. A wireless backhaul node determines one or more reporting nodes for a data volume of a first-type data packet from a plurality of next-hop nodes of the wireless backhaul node on an uplink based on the data volume of the first-type data packet, a data volume of a second-type data packet, and a data volume of a third-type data packet. The wireless backhaul node sends, to the one or more reporting nodes, a buffer status report used to indicate the data volume of the first-type data packet. At least one of the first-type data packet, the second-type data packet, and the third-type data packet includes a data packet from an adaptation layer entity of the wireless backhaul node and/or a data packet from a radio link control layer entity of the wireless backhaul node.
