  • Patent number: 11956722
    Abstract: A wireless device receives parameters, including a first discontinuous reception (DRX) configuration associated with unicast transmissions in a cell and a second DRX configuration associated with multicast and broadcast services (MBS) in the cell. The wireless device may also receive a power saving (PS) indication indicating not to start a DRX on duration timer. The PS indication may be applied for the first DRX configuration; and it may not be applied for the second DRX configuration. The wireless device may further skip monitoring, in a first DRX on duration of the first DRX configuration, first physical downlink control channels (PDCCHs) for the unicast transmissions based on receiving the PS indication. The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.
