Abstract: Examples synchronization signal configuration methods and apparatus are described. One example method is applied to a relay network including a first node and a second node, and the first node is a parent node of the second node. The example method includes sending synchronization signal configuration information by the first node to the second node, where the synchronization signal configuration information is used to indicate M first synchronization signal time-frequency positions and N second synchronization signal time-frequency positions in a candidate synchronization signal time-frequency position set. The first synchronization signal time-frequency position is used by the second node to send a first synchronization signal, the second synchronization signal time-frequency position is used by the second node to receive or detect a second synchronization signal, the candidate synchronization signal time-frequency position set includes W synchronization signal time-frequency positions, and W≥(M+N).

Abstract: The present disclosure relates to control information sending methods in a wireless communications system. In one example waveform control information sending method, a network device obtains control information that includes uplink transmission waveform indication information, and sends the control information to a terminal. After receiving the control information, the terminal determines, based on the control information, a waveform used to send uplink data.

Abstract: An antenna includes: at least three radio frequency interfaces and a feed network, where each of the radio frequency interfaces is connected to a radio frequency channel between the radio frequency interface and a RRU. A first interface is configured to receive a signal from the RRU, and transmit the signal to a second interface by using the feed network. The second interface is configured to send the signal to the RRU. The feed network includes a main feed circuit, a calibration signal circuit, and a switch. The calibration signal circuit is configured to transmit a calibration signal from the first interface to the second interface, where the calibration signal is used to calibrate a phase and an amplitude of the radio frequency channel connected to the first interface. The switch is configured to isolate the calibration signal from a signal on the main feed circuit.

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.
