Abstract: A number of embodiments can describe the operation of a UE in an unlicensed spectrum. Operating a UE in an unlicensed spectrum can include processing a PDCCH transmission provided by an eNodeB to identify a resource for a transmission of the SR message and based on the resource identified in the PDCCH, generating a PUCCH transmission comprising the SR message for the eNodeB.

Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

Abstract: Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.

Abstract: Technology for a user equipment (UE) operable to decode grant Self-defer less downlink control information (G-D 5 CI) received from a Next Generation NodeB (gNB) is disclosed. The UE can decode the G-DCI received from the gNB in a MulteFire system. The UE can identify grant less uplink DCI components included in the G-DCI. The UE can perform a grant less uplink transmission with the gNB based on the grant less uplink DCI components in the G-DCI received from the gNB.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for generating a report result based on a set of measurements performed at measurement gaps during a reporting period. The set of measurements are performed on a reference signal at a first bandwidth part (BWP) or a second BWP when BWP switching is performed. The first BWP has a first measurement gap configuration, the second BWP has a second measurement gap configuration. The measurement gaps of the reporting period are configured according to a third measurement gap configuration that is determined based on the first measurement gap configuration and the second measurement gap configuration.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic beamforming in control channels, by transmitting downlink control channels to user equipment (UEs) in a number of orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A first OFDM symbol of the number of OFDM symbols can be transmitted using first beamforming parameters in a first direction, and a second OFDM symbol of the number of OFDM symbols can be transmitted using second beamforming parameters different from the first beamforming parameters and in a second direction different from the first direction. The number of OFDM symbols used, as well as other parameters, can be dynamically adjusted in subsequent subframes. Other embodiments are described.

Abstract: Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within a prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.
