    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: One embodiment of the invention describes a synchronization signal sending method applied to an unlicensed frequency band. To ensure transmission fairness, a network device performs listen before talk (LBT) before a start time for transmitting a synchronization signal, to determine whether a channel is busy or idle. When the channel is busy, the network device cannot transmit the synchronization signal at the expected start time for transmitting the synchronization signal. Therefore, the network device performs LBT again within a preset time length after the start time, and sends the synchronization signal when determining that the channel is idle by performing LBT again. When the channel is idle, the network device preempts a channel resource, and sends the synchronization signal the expected start time for transmitting the synchronization signal.

    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 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.
