Abstract: This application provides a communication method and apparatus. The method is applied to an unlicensed band, and includes: receiving first information sent by a network device, where the first information includes a Q value or a first parameter, and the first parameter indicates a status of a discovery burst transmission window DBTW; and determining the status of the DBTW based on the Q value or the first parameter. According to the solution provided in this application, a terminal device can determine the status of the DBTW, to quickly implement timing synchronization with the network device.

Abstract: This application discloses a directional measurement method and a device. In this solution, a terminal device may determine a to-be-measured receive beam, and perform RSSI measurement on the to-be-measured receive beam. According to the method, the terminal device may perform RSSI measurement on the to-be-measured receive beam in a targeted manner, and does not need to perform RSSI measurement in all directions. Therefore, in the method, directional RSSI measurement of the terminal device can be implemented, time and power that are consumed by the terminal device to perform RSSI measurement can be reduced, and RSSI measurement efficiency of the terminal device can be improved.

Abstract: This application provides a method for transmitting an SS/PBCH block and an apparatus. The method includes: A terminal device receives one SS/PBCH block in an SS/PBCH block burst set, and then obtains indication information based on the one SS/PBCH block. The indication information may be used to indicate candidate indexes of at least one SS/PBCH block in the SS/PBCH block burst set, and a quantity of the candidate indexes is greater than 64. For example, the quantity of candidate indexes may be 128, 160, 180, 196, 240, or the like. A network device may not be limited to 64 candidate indexes. In other words, a quantity of candidate positions used to send the SS/PBCH block is not limited to 64. Therefore, the network device may send a larger quantity of SS/PBCH blocks to the terminal device.
