Abstract: A method for dynamically dividing or consolidating sub-bands in-between Clear Channel Assessment (CCA) status measurements upon detection of a CCA bandwidth adjustment condition is provided. The method includes determining at least a single CCA status for at least a single sub-band during a first period, and detecting a CCA bandwidth adjustment condition for dividing the single sub-band into two or more separate sub-bands, where a combination of the two or more separate sub-bands occupies the same frequency band as the single sub-band. The method also includes determining a separate CCA status for each of the two or more separate sub-bands during a second period. An apparatus for performing this method is also provided.

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.
