Abstract: A terminal device sends information to a network device, where the information indicates a capability that is of the terminal device to detect an interference signal and that is in multi-user multiple-input multiple-output pairing transmission. After the terminal device sends the information to the network device, the terminal device receives indication information from the network device, where the indication information indicates data transmission information of a second terminal device. The terminal device detects and eliminates the interference signal based on the indication information. According to the embodiments, the network device determines, based on the information, that the capability of the terminal device to detect the interference signal meets a preset condition, and sends the indication information to the terminal device. The indication information is used by the terminal device to detect and eliminate the interference signal, to ensure that the terminal device can better detect and eliminate the interference signal.

Abstract: This application relates to a power determining method and a device. A first terminal device receives first reporting information from a second terminal device through a sidelink, where the first reporting information includes first interference information, and the first interference information indicates adjacent-channel interference generated for the second terminal device when a third terminal device and/or a fourth terminal device send/sends first sidelink information. The first terminal device determines a transmit power of the third terminal device based on the first reporting information. In embodiments of this application, when a transmit power of a sending device is determined, adjacent-channel interference to a receiving device may be considered, so that the determined transmit power is more accurate.
