Abstract: Embodiments relate to the field of wireless communication technologies and provide a method for performing channel sounding, a network-side device, and a terminal. A first terminal sends a resource scheduling request to a network-side device when the first terminal starts a communication connection with a second terminal. The resource scheduling request carrying information about the second terminal requests the network-side device to allocate a transmission resource for channel sounding between the first terminal and the second terminal. The first terminal receives a sounding reference signal sent by the second terminal, and obtains information of a channel for communication between the first terminal and the second terminal. The method enables quick and effective channel sounding between terminals, thereby increasing communication efficiency between the terminals.

Abstract: A WLAN system resource indication method and apparatus are provided. The method includes: generating, by an access point, a frame that carries resource indication information; and sending, to multiple stations, the frame that carries the resource indication information. The resource indication information includes multiple pieces of sub resource indication information. Correspondingly, each piece of the sub resource indication information uniquely corresponds to one of the multiple stations. Therefore, a station side does not need read the entire resource indication information, so as to reduce resource overheads and improve efficiency.
