Publication number: 20250024368Abstract: 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.Type: ApplicationFiled: September 26, 2024Publication date: January 16, 2025Inventors: Prasada Reddy KADIRI, Alberto RICO ALVARINO, Le LIU, Umesh PHUYAL, Linhai HE, Huilin XU

Patent number: 11765182Abstract: A system for location-aware authentication is configured to receive an authentication request associated with an identifier of a user for accessing an application and retrieves user information associated with the identifier and the application. The system then determines that the user information includes a geofence and information associated with a device of the user. Based on the geofence and the device information, the system sends a geolocation data request to the device, causing the device to gather and send the device's current geolocation data to the computing system. A data structure is generated to store data related to the device's current geolocation and sent to the application, which in turn causes the application to grant or deny the authentication request.Type: GrantFiled: October 23, 2020Date of Patent: September 19, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Olena Lanxin Huang, Jia Le He, Samir Vasantbhai Shah, Andrew Pickering
