Claim 5:
6. An integrated access and backhaul (IAB) node, comprising:
a transceiver, configured to receive a transmission configuration message, wherein the transmission configuration message comprises transmission configuration index information and a transmission parameter corresponding to the transmission configuration index information, the transmission configuration index information is used to identify different transmission modes, and each transmission mode comprises at least one of: spatial multiplexing transmission between a mobile terminal (MT) and a distributed unit (DU) of the IAB or non-spatial multiplexing transmission between the MT and the DU of the IAB; wherein the transmission parameter comprises information of effective time; the information of the effective time is used to indicate the effective time of the transmission parameter, and the effective time comprises one or more slots; or the transmission parameter comprises a period and an offset, wherein the period and the offset are used to determine a length of the period and a time location at which the transmission parameter is effective in the period; and
a processor, configured to: obtain the transmission configuration index information; determine, based on the transmission configuration index information, the transmission parameter corresponding to the transmission configuration index information; and perform data transmission by using the determined transmission parameter.
