    Abstract: Systems and techniques are provided for wireless communication. A first network entity (e.g., a user equipment (UE)) can receive information indicative of a configuration for multicast discontinuous reception (DRX). The information can be received from a second network entity (e.g., a base station). The first network entity can perform unicast data communication using one or more multicast DRX cycles of a plurality of multicast DRX cycles corresponding to the configuration, wherein the unicast data communication is performed between the first network entity and the second network entity. A second network entity (e.g., a base station) can transmit, to a user equipment (UE), information indicative of a configuration for multicast discontinuous reception (DRX). The second network entity can perform unicast data communication with the UE using one or more multicast DRX cycles of a plurality of multicast DRX cycles corresponding to the configuration.

  • Publication number: 20240114449
    Abstract: A network node may transmit a first signal to a first radio at a user equipment (UE). The UE may receive the first signal from the network node. The first signal may include a first configuration for a second radio at the UE. The UE may operate the second radio in a first mode based on the first configuration received via the first radio. The first radio may have a lower power consumption than the second radio or the second radio may have the lower power consumption than the first radio. For example, one radio may be a low-power wake-up radio (LP-WUR) having a lower power consumption than a main radio (MR) at the UE. The network node and the UE may communicate with one another via the second radio at the UE based on the first configuration transmitted to the first radio.
