  • Discontinuous reception (DRX) operations with flexible scheduling of data communications
    Patent number: 10791518
    Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to start a discontinuous reception (DRX) inactivity timer based at least in part on a data communication (e.g., a slot in which a downlink data communication and/or an uplink data communication is scheduled), rather than starting the DRX inactivity timer in a slot in which a corresponding downlink control channel communication is received. In this way, the UE may increase the duration of time that the UE is in a sleep state, especially when the data communication is scheduled to occur with a long delay after the downlink control channel communication, thereby conserving battery power of the UE. Some of these techniques and apparatuses may be flexibly configured to conserve battery power of the UE depending on a flexible scheduling of data communications.

  • Forbidden network list management
    Patent number: 10791463
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to include procedures to mitigate denial of service (DoS) attack by a rogue base station when the initial non-access stratum (NAS) messages between the UE and a mobility management entity (MME) is unprotected. UE may maintain a temporary forbidden network list, which resides outside a subscriber identity module (SIM), and update a forbidden network list, which resides on the SIM, only under certain conditions. For example, a visited network, from which the UE receives a reject message, may be added to the forbidden network list on the SIM only when a counter associated with the visited network is equal to a maximum counter value, which is configured by the UE.
