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 downlink synchronization signal sending method includes: generating, by a base station, notification information including a status indication indicating a sending status of a downlink synchronization signal on an unlicensed frequency band, where the sending status indicates whether the downlink synchronization signal is successfully sent or fails to be sent; and sending, by the base station, the notification information by using a licensed frequency band. The downlink synchronization signal is sent with assistance of the licensed frequency band, to improve efficiency of sending the downlink synchronization signal on the unlicensed frequency band.

Abstract: Embodiments of the present invention provide a method which includes: sending a first channel quality measurement report, wherein the first channel quality measurement report indicates a channel noise value measured in a first time period by a first station in a second antenna mode when a third station and a fourth station communicate with each other in a first antenna mode; and receiving an grant frame sent by the AP based on the first channel quality measurement report, wherein the grant frame carries first instruction information and/or second instruction information. A success rate of space-shared communication between station pairs can be increased.

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 resource allocation method, a base station, and a terminal. The method includes: A base station sends a configuration message to a terminal, where the configuration message is used to configure, for the terminal, a random access channel RACH resource used in a channel occupancy time COT. The base station receives a random access request that is sent by the terminal based on the RACH resource allocated by using the configuration message. According to embodiments of this application, a random access latency of the terminal can be reduced.

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: This application discloses a wireless communication method, including: receiving, by a network device, uplink transmission of a first terminal in first duration of channel occupancy duration of the first terminal, where the channel occupancy duration of the first terminal further includes second duration, and the second duration is later than the first duration; and performing, by the network device, downlink transmission in the second duration, where a sum of the first duration and the second duration is less than or equal to the channel occupancy duration of the first terminal. This application further discloses a network device and a terminal that correspond to the wireless communication method. By applying the method and devices, a resource obtained through contention by a terminal applied to an unlicensed frequency band can be properly used, to improve operating efficiency of the unlicensed frequency band.

Abstract: In a RA-RNTI processing method, after an LBT success, NR-U UE randomly selects a preamble preamble, and selects an available random access time-frequency resource RO; sends the preamble on the selected RO; and generates a RA-RNTI based on the RO. Specifically, a first indicator sent by a network apparatus may be received, where the first indicator is used to indicate time information or position information of a RAR; and the NR-U UE detects a PDCCH only within a time window (the RAR) indicated by the first indicator, where the PDCCH is scrambled by the gNB by using a same RA-RNTI.
