  • Patent number: 11039497
    Abstract: A core network receives data from at least one of an AF, a DN, or a UE. A UPF having small data capability processes the data for transport with a low overhead and without initiating a bearer set up protocol. The data may be transported between the UE and the UPF as an RRC payload over a NAS protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as an RRC payload. The data may be received as uplink data from a UE, e.g., in an RRC payload. The UPF may process the RRC payload to obtain the data and may transport the data to the AF or DN. The UPF may perform IP header compression, data encryption, and/or buffering of data for a UE in an idle mode.

  • Patent number: 10959203
    Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using EDT. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling connection with a RAN node but not with a core network to send the event report using EDT. The RAN node may then release the signaling connection, either immediately or after the LS returns a single response to the UE.

  • Publication number: 20210084559
    Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. For example, in one aspect a wireless communication technique takes into account the load of a relay before a UE is switched from one relay to another. In another example, a wireless communication technique ensures that UEs are handed over to relays that will be able to serve the UE as the mobile relay continues to follow its expected path (such as streets or tracks), which may be known or determined.

  • Patent number: 10952178
    Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using control plane (CP) optimization with optional use of Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using CP optimization. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling association with a RAN node to send the event report using CP optimization and optionally using EDT. The RAN node may then release the signaling association after the LS returns a single response to the UE.

  • Publication number: 20200404720
    Abstract: A method, an apparatus, and/or a computer program product for wireless communication are provided. Radio capability signaling (RACS) optimization for the radio access technology (RAT) may be deployed for some user equipments (UEs) in a network to reduce a signaling overhead associated with identifying UE radio capabilities. The UEs may be configured with a set of UE radio capability identifiers, such as a UE radio capability identifier for a narrowband (NB) RAT, a UE radio capability identifier for a non-NB RAT, and/or the like. A UE may provide a single UE radio capability identifier corresponding to a type of RAT to which the UE is to connect. The BS may determine that the UE supports RACS optimization for the RAT. If the UE does not provide the UE radio capability identifier, the BS may infer that the UE does not support RACS optimization.

  • Publication number: 20200404719
    Abstract: Methods, systems, and devices for wireless communications are described that provide for truncated identification indicators. A user equipment (UE) may receive control signaling indicating a truncating configuration for an identification indicator. The truncating configuration may indicate a set of bits within an initial identification indicator to remove to generate a truncated identification indicator. The UE may remove the indicated set of bits and transmit the truncated identification indicator to a base station. The base station may receive the truncated identification indicator and reconstruct the initial identification indicator according to the truncating configuration. The base station may reconstruct the initial identification indicator by adding the set of bits (e.g., removed by the UE to generate the truncated identification indicator) to the truncated identification indicator.
