Abstract: This application provides a transmission parameter configuration method and an apparatus. The method includes: A first node receives a transmission configuration message, where the transmission configuration message includes transmission configuration index information and a transmission parameter corresponding to the transmission configuration index information, and the transmission configuration index information is used to identify different transmission modes; the first node obtains a transmission indication message, where the transmission indication message includes the transmission configuration index information, and the transmission indication message is used to indicate the first node to apply the transmission parameter corresponding to the transmission configuration index information; and the first node performs, based on the transmission configuration index information, data transmission by using the transmission parameter corresponding to the transmission configuration index information. The method can meet requirements of more application scenarios, support more transmission modes, and reduce overheads caused by transmission parameters.

Abstract: This application provides a flow control method and apparatus, and relates to the field of communications technologies. A relay device indicates flow control to an upper-level node to avoid spectrum resources waste because of excessively small amount of data transmission or an excessively large amount of data transmission from an upper-level node. The method includes: A first node determines to indicate a second node to perform flow control; and the first node sends a first flow control indication to the second node. The first flow control indication is carried in adaptation layer control signaling, an RLC control message, or a MAC CE. The first flow control indication includes identifiers of one or more bearers and flow control information. The second node is a relay node or a donor base station.

Abstract: This application provides a method and an apparatus for determining an uplink resource. The method includes selecting a target uplink resource among the resources on a plurality of uplink carriers, and sending, to a network device using the target uplink resource, a beam failure recovery request message. In one embodiment, when there is a plurality of uplink carriers, a resource used for the beam failure recovery request message may be selected by a terminal device from the plurality of uplink carriers, to improve the efficiency of beam failure recovery.
