Abstract: The present disclosure relates to signal transmission methods and apparatuses. In one example method, a transmitting end groups multiple modulation symbols into multiple groups of modulation symbols, and adds one or more preset symbols to each group of modulation symbols to obtain extended symbols. Then, the transmitting end performs second-level precoding on at least one group of extended symbols corresponding to each group of antenna ports to obtain a symbol corresponding to each antenna port in each group of antenna ports. In the second-level precoding, a dimension of a precoding matrix for each group of precoding antenna ports is related to a quantity of groups and a quantity of antenna ports included in the group of antenna ports. Finally, the transmitting end sends the symbol corresponding to each antenna port.

Abstract: This application discloses a resource multiplexing method and apparatus. In this application, a first node receives first configuration information sent by a second node, where the first configuration information includes first guard interval information associated with a first timing mode of an MT. The first node receives second configuration information sent by the second node, where the second configuration information includes second guard interval information associated with a second timing mode of the MT. Guard interval information configured by the second node is associated with different timing modes, so that the first node can obtain the guard interval information corresponding to the different timing modes, to improve flexibility of resource multiplexing performed on an access link and a backhaul link.
