Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using frequency division multiplexing. The wireless device may establish a first wireless link with a first base station according to a first radio access technology (RAT) and a second wireless link with a second base station according to a second RAT. 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 the wireless device has uplink activity scheduled according to both the first RAT and the second RAT. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth using frequency division multiplexing.

Abstract: A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

Abstract: Apparatuses, systems, and methods to indicate power transmission capability for a wireless device. A wireless device may connect to a base station (BS). The wireless device may transmit information regarding transmit power capability to the BS. The wireless device may indicate support for full power transmit capability for a subset of TPMIs for which it provides full power transmit capability, e.g., in a bitmap. This subset of TPMIs may be less than all of the available TPMIs (i.e., it may be a strict subset of the available TPMIs). Full power transmission capability of these indicated TPMIs may be provided via antenna switching and/or antenna virtualization. The wireless device may perform uplink transmission to the BS according to the transmit power capability indicated in the information. For example, the UE may transmit data using the antenna virtualization related to the subset of the TPMIs.

Abstract: This disclosure relates to using a wake up signal in conjunction with cellular communication in unlicensed spectrum. A cellular base station may provide a wake up signal on an unlicensed frequency channel after successful completion of a listen-before-talk procedure. The wake up signal may include a preamble configured for coherent detection, and information indicating channel occupancy time for a cellular communication by the cellular base station and a cell identifier for the cellular base station. A wireless device may monitor the unlicensed frequency channel for a wake up signal, and may determine whether to monitor the unlicensed frequency channel for control channel signaling based on whether a wake up signal is received, and potentially also based on the contents of the wake up signal if a wake up signal is received.

Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.

Abstract: Apparatuses, systems, and methods for performing timing synchronization between a base station and a user equipment device within an unlicensed spectrum band. In some scenarios, beamforming tracking may also be performed. Upon determining that a transmission medium within the unlicensed spectrum band is available for transmission, a base station may transmit a plurality of synchronization signal blocks (SSBs), or a plurality of copies of one SSB, with associated remaining minimum system information (RMSI) blocks, within a single time instance within a SSB burst window. The SSBs may be transmitted at different frequency positions and according to distinct beamforming configurations. The SSBs and RMSI blocks may be configured such that a receiving user equipment device may determine the time-domain, and optionally the frequency-domain, position of the SSB and RMSI within the SSB burst window, to allow timing synchronization and optionally beamforming tracking.

Abstract: An enhanced listen-before-talk procedure may be performed by a device for efficiently accessing and utilizing available resources. The procedure may include specifying input parameter values pertaining to intended wireless communications of the device, adjusting output parameter values based on the input parameter values and an access history of the device, and determining whether to access at least a portion of the wireless communication resources to conduct the wireless communications, based at least on the output parameter values. The output parameter values may pertain to wireless communication resources accessible to the device, and the access history may keep track of wireless communication resource accesses previously made by the device. Input parameter values may include requested channel occupation time, requested frequency resource, requested transmission power, and/or priority and/or urgency of requested transmission, while output parameter values may include energy detection threshold, contention window size, and/or extended clear channel assessment bypass.An enhanced listen-before-talk procedure may be performed by a device for efficiently accessing and utilizing available resources.
