WAKE UP SIGNAL FOR MULTICAST GROUP NOTIFICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17388434 titled 'WAKE UP SIGNAL FOR MULTICAST GROUP NOTIFICATION
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The invention focuses on a user equipment (UE) receiving control signaling from a base station, indicating a multicast or broadcast wake up signal (WUS) format. The UE then receives a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle, based on the control signaling. The multicast or broadcast WUS provides information about upcoming transmissions for a set of multicast or broadcast services (MBSs). If the UE is subscribed to a specific MBS from the set and the multicast or broadcast WUS indicates an upcoming transmission for that MBS, the UE will monitor for the transmission during an active duration of the C-DRX cycle. Otherwise, the UE will enter a sleep mode to conserve power.
- User equipment (UE) receives control signaling from a base station indicating a multicast or broadcast wake up signal (WUS) format.
- UE receives a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle.
- Multicast or broadcast WUS provides information about upcoming transmissions for a set of multicast or broadcast services (MBSs).
- If UE is subscribed to a specific MBS and the multicast or broadcast WUS indicates an upcoming transmission for that MBS, UE will monitor for the transmission during an active duration of the C-DRX cycle.
- Otherwise, UE will enter sleep mode to conserve power.
Potential Applications
This technology can be applied in various wireless communication systems, such as cellular networks, to efficiently manage power consumption and optimize the reception of multicast or broadcast services.
Problems Solved
1. Power consumption: The invention allows user equipment to enter sleep mode when there are no relevant upcoming transmissions, conserving power and extending battery life. 2. Efficient reception: By providing control signaling and wake up signals, the system ensures that user equipment only monitors for relevant transmissions, reducing unnecessary power usage and improving overall efficiency.
Benefits
1. Power savings: User equipment can conserve power by entering sleep mode when there are no relevant transmissions, leading to longer battery life. 2. Improved efficiency: By monitoring for relevant transmissions based on control signaling, user equipment can optimize its reception of multicast or broadcast services, reducing unnecessary power consumption and improving overall efficiency.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station that indicates a multicast or broadcast wake up signal (WUS) format. The UE may receive a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle in accordance with the control signaling. The multicast or broadcast WUS may indicate upcoming transmissions for a set of multicast or broadcast services (MBSs). If, for example, the UE is subscribed to a first MBS from the set of MBSs and the multicast or broadcast WUS indicates an upcoming transmission for the first MBS, the UE may monitor for the upcoming transmission during an active duration of the C-DRX cycle. Otherwise, the UE may enter a sleep mode to conserve power.
