    Abstract: In a method, a terminal device reports, to a network device, a full-power transmission codebook subset corresponding to a frequency band supported by the terminal device before transmission channel switching. The network device or the terminal device in a communications system may determine, according to a specified rule and full-power transmission codebook subsets corresponding to a plurality of source frequency bands, a full-power transmission codebook subset corresponding to a target frequency band after transmission channel switching. The plurality of source frequency bands are frequency bands in which a plurality of target antenna ports are located before antenna port switching, and the plurality of target antenna ports are antenna ports in the target frequency band after antenna port switching.

    Abstract: A positioning signal sending method and apparatus are provided. A first signal is generated, where duration of a first rising edge of the first signal is less than duration of a first falling edge, the duration of the first rising edge is duration of a rising edge of a main lobe waveform of the first signal, and the duration of the first falling edge is duration of a falling edge of the main lobe waveform of the first signal; and the first signal is sent. In embodiments of this application, rising time of a main lobe waveform of a signal generated is short, and shorter rising time of the main lobe waveform is more conducive to distinguishing two adjacent paths or identifying a first arrival path of a received signal.

    Abstract: A first transmitting terminal sends a first channel state information-reference signal CSI-RS in N frequency domain units, where N is a positive integer. The first transmitting terminal detects channel state information CSI sent by K receiving terminals, where the CSI sent by the K receiving terminals is determined based on the first CSI-RS, and K is a positive integer. The first transmitting terminal updates a transmit power of the first transmitting terminal in the N frequency domain units based on the CSI sent by the K receiving terminals. When updated powers of F frequency domain units in the N frequency domain units are greater than a preset threshold, the first transmitting terminal sends user data in at least one of the F frequency domain units, where F is a positive integer less than or equal to N.
