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 discloses a signal transmission method, including: obtaining, by a terminal device, to-be-transmitted data, uplink control information, and a demodulation reference signal; mapping the to-be-transmitted data, the uplink control information, and the demodulation reference signal to generate multiplexed symbols. The multiplexed symbols include DFT-s-OFDM symbols or OFDM symbols. N first multiplexed symbols are located on one side or two sides of a second multiplexed symbol. A location relationship between each of the N first multiplexed symbols and the second multiplexed symbol satisfies a mapping condition. N is an integer greater than or equal to 1. The first multiplexed symbol is a multiplexed symbol to which the uplink control information is mapped, and the second multiplexed symbol is a multiplexed symbol to which the demodulation reference signal is mapped.

Abstract: This application provides a method and apparatus for determining a resource in a relay system. By receiving resource indication information transmitted by an upper-level node, a first node determines the availability of a symbol in a first resource set located between a first hard resource set and a second hard resource set, and communicates with the upper-level node on the symbol based on the resource indication information to maximally improve resource utilization.

Abstract: In a transmission parameter configuration method, 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 to the first node to apply the transmission parameter corresponding to the transmission configuration index information. 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 symbol processing method and related apparatus. The method includes: dividing a plurality of obtained complex-valued symbols into a plurality of sets, where each set corresponds to one transmit symbol, and the plurality of sets include a first set corresponding to a first transmit symbol; and mapping a first sequence and a second sequence to the first set, where an end position of the first sequence is a position of intercepting a cyclic prefix (CP) in the first transmit symbol, and an end position of the second sequence is an end position of the first transmit symbol. By mapping the sequences to the sets, an original cyclic prefix (CP) can be extended using a sequence with a flexible length, and flexible guard periods of different lengths can be configured for different users by adjusting the length of the sequences.
