Abstract: The application relates to beam management for a client device in a power saving state. When the client device is in the power saving state, the client device monitors serving beams of a network access node based on a serving beam configuration. The serving beam configuration indicated the serving beams to be monitored by the client device in the power saving state. If the client device detects a beam failure during the serving beam monitoring in the power saving state, the client device performs a beam reconfiguration procedure. The beam reconfiguration procedure informs the network access node about the change in serving beam status and allows the network access node to update the serving beam configuration.
