  • Publication number: 20200351720
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a broadcast multicast service center (BMSC) device may receive, from a user equipment (UE) and via a first base station associated with a first radio access technology (RAT), a request for evolved multicast broadcast multimedia service (eMBMS) content. The BMSC device may transmit, to an access and mobility management function (AMF) device, a redirection request or a handover request, associated with the UE, from the first base station to a second base station associated with a second RAT. The BMSC device may transmit, to the UE and based at least in part on the UE being redirected or handed over to the second base station, the eMBMS content via the second base station. Numerous other aspects are provided.

  • Publication number: 20200351792
    Abstract: Methods, systems, and devices for wireless communication in a multi-connectivity user equipment (UE) are described. The UE may communicate with one or more base stations via a first radio access technology (RAT). The UE may determine whether the UE is in a selected state. The selected state may correspond to one or more modes of operation (e.g., a doze mode, a relaxed doze mode, an active WiFi communication mode, a low battery mode). The UE may disable communication via a second RAT in response to determining that the UE is in the selected state. The UE may continue to communicate via the first RAT.

  • Patent number: 10750424
    Abstract: Methods, systems, and devices for wireless communication are described for inter-RAT mobility from a first radio access technology (RAT) to a second RAT, including cases in which different RATs correspond to different generations of networks. Approaches described herein include providing a preemptive indication of inter-RAT mobility for one or more geographic areas such to a user equipment (UE). The UE can thus use a mobility procedure to transition from the first RAT to the second RAT that is supported in the UE's location without first attempting an unsupported mobility procedure, reducing transition latency.

  • Patent number: 10701756
    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for transitioning between short DRX and long DRX cycles based on service type to improve performance (e.g., reduce delay) while limiting power consumption. In one example, the UE switches to a long DRX cycle after a DRX Short Cycle Timer, or drxShortCycleTimer, expires. The UE may also switch to a long DRX if the UE receives long DRX MAC control element (CE) from a gNB. In another example, a gNB may configure a radio bearer from a set of radio bearers (data radio bearer (DRB) and/or signal radio bearer (SRB)), denoted by S, to trigger the UE to enter a short DRX cycle.

  • Publication number: 20200092773
    Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.
