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: A beam training method and a related device are disclosed. The method includes: sending, by a first communications device, sidelink control information (SCI) to a second communications device, where the SCI is used to instruct the first communications device to send at least one channel state information-reference signal (CSI-RS) to the second communications device; and sending, by the first communications device, the at least one CSI-RS to the second communications device based on the SCI, where the at least one CSI-RS is used by the second communications device to determine that a beam corresponding to a CSI-RS with highest signal strength in the at least one CSI-RS is a beam for communication between the second communications device and the first communications device. The CSI-RS used for beam training is dynamically sent based on the instruction of the SCI, and therefore, flexibility and efficiency of beam training are improved.

Abstract: Embodiments of this application provide a signal transmission method and a device. The method includes: performing, by a network device, idle carrier sense in a downlink beam direction when a predefined sending time of each synchronization frame in a synchronization frame set arrives, where the synchronization frame set includes N synchronization frames, and each synchronization frame includes at least one synchronization signal block; and sending a synchronization signal block to a terminal in the downlink beam direction in a synchronization frame in which idle carrier sense succeeds, where the synchronization signal block includes a synchronization signal. The network device performs idle carrier sense in the downlink beam direction when the predefined sending time of each synchronization frame arrives, and sends the synchronization signal block including the synchronization signal in the downlink beam direction in the synchronization frame in which idle carrier sense succeeds.
