  • Publication number: 20250151027
    Abstract: Extension of power efficient paging in a wireless network. In some examples, information is buffered for a time period corresponding to a paging slot, or both the paging slot and at least one adjacent slot. The buffered control information is processed to detect paging downlink control information (DCI) and a tracking reference signal (TRS). Based on the processing, the paging message is scheduled in a physical downlink shared channel (PDSCH) in the paging slot. In some examples, quasi-co-located (QCL) processing may be performed on the TRS and the paging DCI paging message, and a paging message is scheduled, based on the QCL processing, in a physical downlink shared channel (PDSCH) in a same or offset paging slot.

  • Patent number: 12289677
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

  • Patent number: 12273858
    Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.

  • Patent number: 12267791
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.

  • Patent number: 12232066
    Abstract: A configuration to allow a base station to be synchronized with an application server to enable the base station to align uplink transmissions of a UE with downlink reception periods of the UE. The base station communicates with a UE using periodic uplink traffic bursts and periodic downlink traffic bursts. The base station selects a time offset to at least one of uplink traffic or downlink traffic to increase an overlap between the uplink traffic bursts and the downlink traffic bursts. The base station sends the time offset to an AF.
