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 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.
