Abstract: The technology of this application relates to a method for transmitting uplink control information. The method includes a network device sending first signaling in a first cell to a terminal device. The terminal device may send uplink control information in a second cell based on the first signaling. The uplink control information may be uplink control information corresponding to the first cell and/or uplink control information corresponding to a third cell. The third cell is a cell other than the first cell and the second cell. According to the method provided in this application, a cell for sending the uplink control information may be dynamically configured for the terminal device, and can improve communication efficiency.

Abstract: Embodiments of this application provide a resource configuration method and apparatus, so as to improve resource utilization during D2D communication. A first terminal device receives scheduling information that is sent by a network device and that is used to indicate an uplink time-frequency resource used for the first terminal device, and the first terminal device can multiplex the uplink time-frequency resource to send a sidelink signal to a second terminal device when an interference value to the network device during sending of the sidelink signal meets a first rule. Therefore, the uplink time-frequency resource of the first terminal device is multiplexed while interference is considered during sidelink transmission, thereby improving resource utilization.

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.

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: Embodiments of this application provide a communication method and a device, so that a terminal device in a communications system implements sidelink communication in an unlicensed frequency band. In an example implementation, a network device in the communications system may send configuration information, to indicate a channel access mode used when the terminal device performs sidelink communication in the unlicensed frequency band. After receiving the configuration information, the terminal device that accesses the network device may perform sidelink communication in the unlicensed frequency band based on the channel access mode indicated by the configuration information. According to this solution, the terminal device in the communications system may implement sidelink communication in the unlicensed frequency band.

Abstract: This application provides a method for configuring a sidelink resource and a communication apparatus. A transmit end user may indicate, by using SCI based on a preempted COT, that last several symbols in a slot are blank symbols, and a receive end may perform LBT in the COT based on a reserved blank, to implement COT sharing. In addition, after the COT is preempted, the transmit end user may flexibly configure periodicity information of a PSFCH resource, and send the periodicity information of the PSFCH resource to a receive end user. With reference to frame structure information, a position of a PSFCH slot in a slot in a corresponding direction can be calculated by users of the transmit end and the receive end by using a modulo operation, to feed back HARQ information in a corresponding slot in which the PSFCH exists.
