    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 guard band indication method on an unlicensed spectrum is described that includes: a network device generating one or any combination of the following four types of information on the unlicensed spectrum: an indication of bandwidth configuration information, an indication of available bandwidth information, an indication of unavailable bandwidth information, or an indication of guard band information; and the network device sends the one or any combination of the foregoing four types of generated information. The one or any combination of the four types of information is used to determine a guard band that is based on a listen before talk (LBT) result.

    Abstract: This application provides a control resource configuration method, which includes: pre-configuring, by a network device, a plurality of control resource sets on a plurality of sub-bands, where the plurality of control resource sets have different priorities; separately performing, by the network device, channel sensing on the plurality of sub-bands, to determine one or more available sub-bands in the plurality of sub-bands; determining, by the network device, one or more to-be-scheduled control resource sets from the plurality of control resource sets based on a priority of each of the plurality of control resource sets; and sending the one or more to-be-scheduled control resource sets on the one or more available sub-bands and within corresponding channel occupancy time, where the control resource set carries downlink control information for a terminal device. A success rate of sending the CORESET is improved without increasing resources required by the CORESET.

    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: This application provides a communications method, which includes: performing, by a network device, LBT on a first carrier, and determining a time offset when the LBT is completed, where the first carrier is used to send a first SS Burst Set, and the time offset is a time offset of an actual transmission time of the first SS Burst Set on the first carrier relative to a configured transmission time of the first SS Burst Set; sending, by the network device, the time offset to a terminal; and receiving, by the terminal, the time offset, and performing rate matching on the first carrier based on the time offset. Thus, the terminal may determine the actual transmission time of the first SS Burst Set based on the time offset, to perform the rate matching and accurately parse downlink data, thereby improving reliability of a communications system.
