Abstract: Embodiments of this application provide a beam management method, a terminal, a network device, and a storage medium. The method includes: when a quantity of reference signals whose RSSIs are greater than a first preset value in reference signals received on a first time-frequency resource on one of one or more beams is less than a second preset value, detecting, by the terminal, a reference signal and/or downlink indication information (used to indicate a sending status of the reference signal on the first time-frequency resource and/or a second time-frequency resource on the beam) from the network device on the second time-frequency resource on the beam. Further, when receiving the downlink indication information on the second time-frequency resource on the beam, the terminal continues to detect a reference signal from the network device on the beam, thereby saving communications system resources.

Abstract: A tracking reference signal (TRS) burst transmission method and apparatus wherein a transmit end determines to send a first TRS burst in the first slot in a maximum channel occupancy time (MCOT), that is, the TRS burst is sent at a start moment of the MCOT, so that a receive end can obtain precise time-frequency synchronization as soon as possible. In addition, when a length of a first MCOT is greater than Y slots, in addition to sending the first TRS burst in the first slot in the MCOT, it is further determined to send a second TRS burst in a slot that is in the first MCOT and whose distance to a start slot of a previous TRS burst is Y slots, to improve effectiveness of the time-frequency synchronization and further improve the reliability of receiving the data at the receive end.

Abstract: One embodiment of the invention describes a synchronization signal sending method applied to an unlicensed frequency band. To ensure transmission fairness, a network device performs listen before talk (LBT) before a start time for transmitting a synchronization signal, to determine whether a channel is busy or idle. When the channel is busy, the network device cannot transmit the synchronization signal at the expected start time for transmitting the synchronization signal. Therefore, the network device performs LBT again within a preset time length after the start time, and sends the synchronization signal when determining that the channel is idle by performing LBT again. When the channel is idle, the network device preempts a channel resource, and sends the synchronization signal the expected start time for transmitting the synchronization signal.

Abstract: This application provides a network device-based communication method, where channel resources are divided according to a specific rule. The method includes: determining, by a network device, at least two channels, where a spacing between center frequencies of two adjacent channels in the at least two channels is a positive integer multiple of a subcarrier spacing or a positive integer multiple of a resource block RB spacing; and communicating, by the network device, by using at least one of the at least two channels. Channel resource division is determined based on the spacing between center frequencies of two adjacent channels, implementing adaptation to an application scenario in which a bandwidth is flexible.
