Display synchronization method, electronic device, and readable storage medium

This application provides a terminal apparatus and method for discontinuous reception (DRX) in an unlicensed band, and may be applied to a scenario in which a terminal device performs communication through a sidelink or a Uu link. A signal receive end monitors a sidelink signal and/or a downlink signal on a grant-free resource configured by a network device, and switches between a non-DRX mode and a DRX mode when a corresponding preset condition is met. Alternatively, a transmit end directly indicates a receive end to use a DRX mode or a non-DRX mode, or indirectly indicates, with assistance of a network device, a receive end to use a DRX mode or a non-DRX mode. In this way, DRX of the receive end can be implemented in a sidelink unlicensed band or a Uu link unlicensed band. This reduces power consumption of the receive end.

This application discloses a directional measurement method and a device. In this one example solution, a terminal device may determine a to-be-measured receive beam, and perform received signal strength indication (RSSI) measurement on the to-be-measured receive beam. 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, directional RSSI measurement of the terminal device can be implemented.

A random access method is described that includes a network device determines a first channel access type used by a terminal device to access a first unlicensed frequency band, where the first channel access type is one of channel access types of an unlicensed frequency band, and there are two channel access types of the unlicensed frequency band: frame based equipment (FBE) and load based equipment (LBE). The network device sends a first system message to the terminal device, where the first system message carries first indication information, and the first indication information is used to indicate the first channel access type. The terminal device obtains the first system message from the network device, and accesses the first unlicensed frequency band by using the first channel access type indicated by the first indication information.

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.
