  • Publication number: 20260164500
    Abstract: Disclosed are techniques for wireless communication, which may be performed by a UE or other device capable of wireless wide area network (WWAN) communication and radio frequency identification (RFID) communication. In some aspects, the RFID operation is scheduled to occur during a discontinuous reception (DRX) cycle OFF period, e.g., during DRX sleep periods. In some aspects, the device can request the network to change the device's DRX configuration so that there are DRX sleep periods of sufficient duration in which the RFID operation may occur. In some aspects, the device can force a change in DRX operation by throttling the WWAN operation. In some aspects, the relative priority of WWAN and RFID transmissions are alternated according to a duty cycle, which causes the RF chain to toggle between WWAN operation and RFID operation.

  • Patent number: 12200613
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a first subscription, of a plurality of subscriptions associated with the UE, is associated with an active service on a first cellular network. The UE may search, for a second subscription of the plurality of subscriptions, for radio access technologies (RATs) and frequency bands that are compatible with a dual active mode of the UE. In some aspects, the UE may detect that the active service on the first cellular network has ended. Accordingly, the UE may search, for the second subscription, for RATs and frequency bands that are compatible with the dual active mode of the UE and for RATs and frequency bands that are incompatible with the dual active mode, before expiry of a timer associated with a power saving state. Numerous other aspects are described.

  • Publication number: 20240098694
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish one or more wireless connections for different subscriptions with a base station. The UE may receive an indication of a temporary mobile subscription identifier (TMSI) from the base station during a registration procedure. The UE may calculate a paging occasion (PO) based on the TMSI and may determine the PO fails to satisfy a threshold timing value. The UE may transmit one or more registration request to trigger additional registration procedures in which base station may transmit a new TMSI. The UE may calculate an updated PO based on the new TMSI. The UE may periodically receive one or more paging messages from the base station in a set of POs based on calculating the updated PO.
