Abstract: The application discloses a wireless communication method that includes receiving, by a network device, uplink transmission of a first terminal in a first duration of channel occupancy duration of the first terminal. The channel occupancy duration of the first terminal further includes a second duration, and the second duration is later than the first duration. The network device performs downlink transmission in the second duration, where the sum of the first duration and the second duration is less than or equal to the channel occupancy duration of the first terminal. The method provides an efficient use of resources obtained through contention in an unlicensed frequency band.

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.
