  • Publication number: 20210314270
    Abstract: Certain aspects of the present disclosure provide techniques for packet buffering. A method that may be performed by a receiving node includes dynamically determining one or more time durations to buffer packets. The one or more time durations can be different than a time duration of a configured timer for buffering the packets. The receiving node may input one or more parameters to a machine learning algorithm and obtain, as output of the machine learning algorithm based on the input one or more parameters, one or more time durations to buffer packets. The receiving node buffers packets for the determined one or more time durations. The receiving node may use machine learning to dynamically determine the one or more time durations to buffer packet. The buffering may be at a radio link control (RLC) reassembling buffer and/or a packet data convergence protocol (PDCP) buffer.

  • Publication number: 20210289407
    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.

  • Patent number: 10972876
    Abstract: Methods, systems, and devices for wireless communications are described for providing local broadcasts for group calls. A user equipment (UE) may request a group call, and either a base station or a local server dedicated to the base station may determine whether to allow the group call based at least in part on an assessed level of interest for the group call. If the group call occurs, the UE may perform one or more aspects of user plane processing for the broadcast data—such as setting Internet protocol (IP) addresses in IP packets, encryption, compression, or media formatting—and may transmit the broadcast data to the base station. The base station may then transmit the broadcast data to one or more interested UEs via one or more multicast transmissions without routing the broadcast data through other network nodes, which may reduce latency and provide other benefits.

  • Publication number: 20210045177
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a network configuration procedure has failed a threshold number of times for a first radio access technology (RAT). The UE may perform a first action to prevent execution of the network configuration procedure until a timer has elapsed based at least in part on determining that the network configuration procedure has failed the threshold number of times. The first action may include transmitting a message that indicates that the UE does not have a capability to communicate using the first RAT, barring a cell or a tracking area of the first RAT or a second RAT that assists with establishing a radio access network connection for the first RAT, and/or refraining from reporting measurement results for the first RAT. Numerous other aspects are provided.

  • Publication number: 20210029671
    Abstract: The disclosure relates to methods, devices, and systems for wireless communications. A wireless communications system may support unicast and broadcast communications for different radio access technologies (RATs). To support the coexistence of different RATs, a user equipment (UE) may report, to a base station, a UE capability message containing a band combination including one or more bands for a first RAT (for example, New Radio (NR)) and one or more bands for a second RAT (for example, Long Term Evolution (LTE)) and an indication of a baseband budget for the second RAT for the band combination. In some implementations, the UE may transmit a broadcast interest indicator to the base station requesting a broadcast service. The base station may configure the UE with a carrier aggregation (CA) configuration based on the UE capabilities, such as the band combination and corresponding baseband budget for the second RAT, and the interest indicator.
