Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method includes: A network device sends resource indication information to a terminal device, so that the terminal device determines, based on the resource indication information, a resource allocated by the network device. The resource indication information is used to indicate location information of a resource in at least one BWP in a system bandwidth and bandwidth information of the at least one BWP. Further, the network device receives, on a resource corresponding to the resource indication information, uplink data sent by the terminal device. It can be learned that, in the embodiments, the network device may indicate a system bandwidth of any size and/or a resource in any BWP in the system bandwidth to the terminal device, so that the terminal device can perform data transmission on the indicated resource.

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.
