Abstract: In at least some embodiments, a method, apparatus, and system for performing communication using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. A mobile device may be configured to receive information regarding traffic steering, i.e., cellular/short-range RAT handover, from nearby short-range access points and/or from a cellular base station. The mobile device may generate or determine mobility information of the mobile device, which indicates an amount of movement of the mobile device. The mobile device may determine whether the mobile device should transition between the cellular RAT and the short-range RAT based at least in part on the traffic-steering information and the mobility information. The mobile device may selectively transition between the cellular RAT and the short-range RAT based on the determination.

Abstract: This disclosure relates to techniques for dynamically adjusting a number of active receiver chains of a wireless device. Based on communication parameters exchanged with a base station, a device may determine a maximum number of receiver chains needed for data reception during one or more time periods. Such dynamic adjustment may enable power savings.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to establish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using multiplexing at a layer above the physical layer. The wireless device may establish wireless links with first and second base stations, respectively, according to first and second radio access technologies (RATs), respectively. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether inter-RAT uplink coexistence in the same frequency band is enabled. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth by multiplexing uplink data for the first RAT and uplink data for the second RAT at a layer above the physical layer.

Abstract: Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In one embodiment, a method includes receiving first information from a UE device requesting voice communication over a packet-switched network. In this embodiment, the method further includes transmitting, in response to the first information, second information to a base station serving the UE device, wherein the second information indicates that the UE device is requesting voice communication over the packet-switched network. In this embodiment, the transmitting is performed prior to establishment of a dedicated bearer by the base station for the UE device. In this embodiment, the second information operates to configure communications between the base station and the UE device to provide a particular quality of service for the packet-switched voice communication using the dedicated bearer.

Abstract: This disclosure relates to techniques for a wireless device to indicate a preferred bandwidth part and duty cycle in a cellular communication system. A wireless device and a cellular base station may establish a radio resource control connection. The wireless device may transmit an indication of a preferred bandwidth part, or a preferred communication duty cycle, or both, to the cellular base station. The cellular base station may select a bandwidth part, or communication duty cycle, or both, based at least in part on the indication provided by the wireless device, and may transmit an indication of the selected bandwidth part, communication duty cycle, or both, to the wireless device. The cellular base station and the wireless device may perform cellular communication using the selected bandwidth part, communication duty cycle, or both.

Abstract: A base station and mobile device (UE) may coordinate transmission of reference signals and reception of corresponding channel state information (CSI) reports. If a periodic reference signal is scheduled for transmission outside the on-duration period of the UE, even if the reference signal corresponds to a periodic CSI report scheduled to be transmitted by the UE during the on-duration period, the base station may not transmit the periodic reference signal, thereby allowing the UE not to prematurely exit a low-power state. The base station may instead transmit an aperiodic reference signal at a specified point in time later than the scheduled transmission of the periodic reference signal. The UE may receive the aperiodic reference signal and either transmit the periodic CSI report or an aperiodic CSI report in response, depending on how close to the start of the on-duration period the transmission of the periodic CSI report is scheduled.

Abstract: This disclosure relates to techniques for network slice selection. A network slice selection function of a cellular network may receive a network slice selection request from a radio access network node of the cellular network. The network slice selection request may be received by the radio access network node from a wireless device. A core network slice (and possibly a radio access network slice) of the cellular network may be selected for the service request. A network slice selection response may be provided to the radio access network node, indicating a control plane entry point address for the selected core network slice. The selected radio network slice may also be indicated in the network slice selection response.

Abstract: Apparatuses, systems, and methods to perform attachment of a wireless device to a next generation gateway via either a base station of a next generation radio access network (RAN) or a mobility management entity of a legacy RAN. An apparatus may be configured to receive an attachment request from a wireless device, determine authentication information via communication with a home subscriber server, determine, based at least in part on the authentication information, whether the wireless device is capable of communicating via the next generation RAT, and send, in response to determining the wireless device is capable, a connection request to a gateway of the next generation RAN. The authentication information may include subscription information associated with the wireless device.
