  • Patent number: 10660029
    Abstract: Technology for improving the selection, transfer, and storage of user equipment (UE) radio capability information is disclosed. A cellular mobile network can be configured to identify radio-access-technology (RAT)-specific radio-capability information relating to RATs supported in the cellular mobile network and communicate the RAT-specific radio-capability information to a UE. The UE can use the RAT-specific radio-capability information to help determine which UE radio capability information to send to the network. In addition, the UE may store a list of supported frequency bands and/or supported frequency-band combinations (LOSB) indexed by network operators and use the list to help determine which UE radio capability information to send to the network. A network node may also selectively remove unnecessary information from UE radio capability information before storing the UE radio capability information at a mobility management entity (MME).

  • Publication number: 20200154395
    Abstract: Methods and apparatus enabling a wireless network to optimize paging channel operation, based on mobile device context information. In one embodiment, the wireless network is a cellular network (e.g., LTE-Advanced), and both base stations and cellular user devices dynamically exchange and maintain a paging agreement. The paging agreement limits the paging channel operation, thereby minimizing unnecessary scanning and usage of irrelevant radio resources. Such paging mechanisms are limited to the air interface between the base station and the mobile device, and are compatible with existing legacy devices and network entities. Networks with appropriately enabled user devices may improve their resource utilization. Base stations may advantageously reclaim freed-up cellular resources to support other services.

  • Patent number: 10630458
    Abstract: Methods and apparatus that enable a wireless network system to dynamically change between full-duplex FDD operation and half-duplex FDD operation in order to take advantage of operational aspects of both modes. In one embodiment, an alternative duplex mode of operation is disclosed (semi-static half duplex FDD operation) that enables coordination between the client device (e.g., UMTS UE) and the base station in order to centralize control of radio resource control (RRC) to the base station. The disclosed methods and apparatus may also advantageously incorporate hybrid ARQ (HARQ) or comparable timing requirements into their operation.

  • Publication number: 20200045587
    Abstract: Devices, methods, user equipment (UE), network core devices, gateway devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, a UE is configured for codec bitrate adaptation via an interface configured to receive a bandwidth indication and a codec awareness indication from an eNB. The UE process the bandwidth indication and identifies, based on the codec awareness indication, a first codec from a plurality of codecs supported by the UE. The UE then configures with the eNB using data encoded with the first codec. This data may, for example, be Voice over Long-Term Evolution (VoLTE) data or other such media data. Selection of the codec or associated codec information may be further based on the codec awareness indication.

  • Publication number: 20200015076
    Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE), comprises one or more baseband processors to derive a dynamic scrambling key, and a memory to store the dynamic scrambling key and a temporary UE identifier (temporary UE ID) assigned to the UE. The one or more baseband processors monitor a paging request for a scrambled UE identifier (UE ID) to determine if the paging request is intended for the UE by unscrambling the scrambled UE ID with the dynamic scrambling key to produce the temporary UE ID. The paging request is intended for the UE if the temporary UE ID produced by unscrambling the scrambled UE ID matches the temporary UE ID stored in the memory. A new dynamic scrambling key may be derived each time the UE returns to a radio resource control idle (RRC_IDLE) state.

  • Publication number: 20190387577
    Abstract: Technology for a user equipment (UE), operable to generate an enhanced buffer status report (eBSR) is disclosed. The UE can identify packets for uplink transmission. The UE can filter the packets for transmission, to identify a number of small packets pending for transmission and a number of larger packets, relative to the small packets, that are pending for transmission in the uplink transmission. The UE can encode the eBSR for transmission to a next generation node B (gNB), wherein the eBSR includes information identifying the number of small packets pending for transmission. The UE can have a memory interface configured to send to a memory the number of small packets pending for transmission.

  • Publication number: 20190373573
    Abstract: Techniques described herein allow for mobile positioning (i.e., the determination of the position of the UE) to be performed when the UE is in Idle mode. In some implementations, assistance data, that is used by the UE as part of the mobile positioning procedure, may be broadcast to the UE or transmitted to the UE within paging messages. The assistance data can potentially be sent to the UE in a number of time slots. In some implementations, the UE may perform measurements needed for mobile positioning only within discontinuous reception (DRX) occasions. Alternatively, in some implementations, the UE may perform measurements needed for mobile positioning outside of DRX occasions.

  • Publication number: 20190349881
    Abstract: Systems and methods of providing location techniques for a NB UE are described. The UE transmits, to a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to the position methods, including that the UE is a NB UE. The UE receives a request for location information that includes a request for positioning measurements for a particular positioning method, a NB message size limit that indicates a limit on an amount of location information to return, and a NB response time to provide the positioning measurements. At least one of the response time or message size limit is different than for the NB UE than for non-NB UEs. The UE enters an idle state, performs the measurements, and transmits at expiry of or before the NB response time, a message containing the measurements.

  • Patent number: 10390189
    Abstract: User Equipment (UE) may skip the Access Class Barring (ACB) procedure for specific services, such as MMTEL voice, MMTEL video, and SMS. In one implementation, NAS layer of a UE may: receive, from an upper layer relative to the NAS layer, a request for a particular service type that is being originated by the UE; receive an indication, from a Radio Resource Control (RRC) layer of the UE, that access to a cell, associated with the UE, is barred; and bypass the indication that access to the cell is barred, when the particular service type matches a predetermined set of service types. The bypassing may include: requesting that the RRC layer establish an RRC connection for the service request, and notifying the RRC layer that the request for the RRC connection corresponds to the particular service type.
