Abstract: Example radio link monitoring methods and apparatus are described. One example method includes performing radio link monitoring (RLM) in a second bandwidth part (BWP) by a terminal device. The terminal device receives first switching information from a network device that is used to indicate that an active BWP includes a first BWP, and switches from the second BWP to the first BWP based on the first switching information. The terminal device removes a measurement result obtained by performing RLM in the second BWP, where the measurement result includes a quantity N1 of one or more out of synchronization (OOS) states or a quantity N2 of one or more in synchronization (IS) states. RLM is performed in the first BWP.

Abstract: The present invention provides a WLAN system resource indication method and apparatus. 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.
