Abstract: Example reference signal measurement methods, example resource indication methods, and example apparatuses are provided. One example method includes receiving at least one reference signal from a network device. Channel state information can then be determined based on some or all of the at least one reference signal. The channel state information can then be reported to the network device based on first duration. When it is determined to activate a first antenna panel and measure the at least one reference signal by using the first antenna panel, the first duration can be determined based on a first constraint relationship. The first antenna panel can be currently not activated.

Abstract: Example antenna panel management methods of a terminal device are described. One example method includes that the terminal device enters a sleep mode from an active mode. When the terminal device is ready to re-enter the active mode from the sleep mode, if sleep duration is less than a preset threshold, a single panel of the terminal device is activated. If the sleep duration is greater than or equal to the preset threshold, a plurality of panels of the terminal device are activated. The terminal device activates a panel based on sleep duration between two consecutive DRX ON modes, so that a suitable panel can be activated in time, and a suitable beam can be further found for communication with a base station.
