Abstract: Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

Abstract: A user equipment (UE), or other network component can operate to generate new radio (NR) communications in millimeter wave (mmW) frequencies. Body proximity sensing (BPS) operations can be performed to determine whether a maximum permissible exposure (MPE) event is triggered. A safe transmit power level associated with the one or more bands can then be used to provide the NR communications. Additionally, determinations of whether various conditions are satisfied to suspend the BPS operations for a period can be evaluated and implemented. The BPS can be configured such that a BPS period of the BPS operations are aligned with a discontinuous reception (DRX) cycle at a beginning of a DRX on-duration of a DRX cycle, wherein the one or more conditions comprise a DRX idle time or state.

Abstract: This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.

Abstract: This disclosure relates to performing cellular communication in unlicensed spectrum in a manner that accounts for the possible existence of hidden nodes by opportunistically introducing the use of RTS and CTS messages. A listen-before-talk procedure may be performed to determine whether a wireless medium is available. When the listen-before-talk procedure is complete, an amount of time until a next possible start time for communicating in the cellular communication system according to a timing synchronization scheme for the cellular communication system may be determined. The wireless medium may be occupied until the next possible start time for communicating in the cellular communication system in a manner selected based at least in part on the amount of time until the next possible start time for communicating in the cellular communication system. Cellular communication may be performed on the wireless medium at the next possible start time for communicating in the cellular communication system.

Abstract: This disclosure relates to techniques for providing robust downlink control information with flexible resource assignments for wireless devices that operate in a restricted bandwidth compared to the system bandwidth. A base station may determine a resource assignment for a wireless device. The base station may transmit downlink control information to the wireless device. The downlink control information may include an indication of a resource assignment for the wireless device. The indication of the resource assignment may include an indication of a first narrowband associated with the resource assignment, and an indication of whether one or more additional narrowbands are associated with the resource assignment. The base station and the wireless device may communicate data according to the resource assignment.

Abstract: Techniques are disclosed relating to a mobile device that communicates over short-range networks and long-range networks. In various embodiments, a mobile device includes one or more radios configured to communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. The mobile device may establish a first connection and a second connection with a network such that the first connection uses the short-range RAT and the second connection uses the cellular RAT. The mobile may collect information about the second connection and communicate the collected information to the network over the first connection. In some embodiments, the information includes a base station identifier, an MCC, an MNC, the cellular RAT and a cellular information age indicating the time since the information about the second connection was collected by the UE.

Abstract: This disclosure relates to providing a reservation signal for cellular communication in unlicensed spectrum. A cellular base station may perform a listen-before-talk procedure on an unlicensed frequency channel. The cellular base station may transmit a reservation signal on the unlicensed frequency channel after successfully performing the listen-before-talk procedure. The cellular base station may perform carrier sensing on the unlicensed frequency channel at least once during the duration of the reservation signal. The cellular base station may perform cellular communication on the unlicensed frequency channel after ceasing transmitting the reservation signal.

Abstract: A network controller, a user equipment (UE) device, and associated methods for conducting intelligent enhanced multimedia broadcast multicast services (eMBMS). A network controller receives user preference information and location information from a plurality of UEs. The network controller selects one or more data packages to transmit using eMBMS in one or more broadcast regions based on the user preference information and the location information. The one or more data packages may comprise an updated machine learning model in a distributed learning application. The network controller provides an indication to a remote device to broadcast the one or more data packages in the respective one or more broadcast regions using eMBMS.
