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: The present disclosure relates to signal transmission methods, devices, and systems. One example method includes sending, by a network device, a plurality of synchronization signal/physical broadcast channel (SS/PBCH) blocks in one or more burst set windows, where the one or more burst set windows include a plurality of candidate positions that are used to transmit the plurality of SS/PBCH blocks. Two or more SS/PBCH blocks sent at two or more positions of the plurality of candidate positions in the one or more burst set windows are quasi co-located (QCL) with each other and correspond to a same SS/PBCH block index.

Abstract: Embodiments of this application disclose a signal transmission method, a related device, and a system. The method may include: receiving first indication information sent by a network device, where the first indication information is used to indicate an uplink resource that is allocated by the network device to a terminal in a first bandwidth; the resource indicated by the first indication information includes an integer quantity of resource blocks evenly distributed in a part or all of the first bandwidth; performing uplink transmission in a detected idle second bandwidth; and sending second indication information to the network device, where the second indication information is used to indicate the second bandwidth. This solution can support flexible bandwidth transmission, and can better adapt to a multi-bandwidth scenario supported by a next-generation new radio technology.

Abstract: This application provides a random access method, apparatus, and device, and a storage medium. The method includes: A terminal device scrambles first identification information of the terminal device by using an OCC, and sends a first message to a network device. After receiving the first message sent by the terminal device, the network device sends a second message to the terminal device based on the first message, where the second message includes identification information of one or more terminal devices that succeed in random access, so that the terminal device can determine, based on the identification information of the one or more terminal devices the one or more terminal devices include the first identification information of this terminal device, whether this terminal device succeeds or fails in random access.

Abstract: Embodiments provide a HARQ feedback method and apparatus, to resolve a current-technology problem that subsequent transmission is affected because a terminal device cannot provide a HARQ feedback in time due to uncertainty of LBT. The method includes: A first terminal device performs LBT, and sends HARQ information of a plurality of second terminal devices on a channel resource on which the LBT succeeds, so that for different second terminal devices, the first terminal device does not perform LBT for a plurality of times, thereby reducing LBT overheads, and overcoming a problem that HARQ information corresponding to some second terminal devices cannot be sent in time due to an LBT failure.
