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 method for radio link monitoring on an unlicensed spectrum and a communications apparatus. The method includes: A terminal device determines one or more channel occupancy times COTs. The terminal device detects one or more downlink reference signals within the one or more COTs. The terminal device determines, based on the downlink reference signal detected within the one or more COTs, whether a channel needs to be reconnected. According to the method for radio link monitoring on an unlicensed spectrum that is provided in this application, accuracy of radio link monitoring performed on an unlicensed spectrum can be ensured, precision of a result of the radio link monitoring can be improved, and a more accurate result of the radio link monitoring can be obtained, thereby improving communication efficiency and communication quality.

Abstract: Example hybrid automatic repeat request (HARQ) feedback methods and apparatus are described. One example method includes sending first indication information by a base station, where the first indication information is used to indicate a terminal to perform HARQ feedback. Second indication information is sent by the base station, where the second indication information includes second time information used to indicate the terminal to perform the HARQ feedback. The base station receives HARQ feedback information of the terminal. In one example method, the base station may send the first indication information within a first channel occupancy time (COT), and send the second indication information within a second COT.

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. SS/PBCH blocks sent at positions corresponding to at least two particular indexes have a quasi co-located (QCL) relationship.
