Abstract: Described is an apparatus of an Evolved Node-B (eNB) operable to communicate with a User Equipment (UE) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process one or more configuration transmissions from the eNB carrying one or more parameters for Grantless Uplink (GUL) transmission. The second circuitry may be operable to determine one or more GUL subframes of an acquired Maximum Channel Occupancy Time (MCOT) on time-domain resources allocated for GUL transmission from the UE. The third circuitry may be operable to generate a GUL transmission during the one or more GUL subframes of the acquired MCOT in accordance with the one or more parameters for GUL transmission.

Abstract: Technology for a user equipment (UE) operable to decode grant 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: A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE may also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.

Abstract: Systems and methods of using a frame structure by a NB-IoT UE are described, The UE receives an anchor segment on an anchor channel and a data segment on a data channel both in an unlicensed spectrum. If a 3N1 frame structure is used: a NPSS, NSSS and NPBCH are in a highest index anchor carrier of contiguous anchor carriers and SIB in a lowest index anchor carrier, and if a 3N2 frame structure is used a single narrowband carrier comprising the NPSS, NSSS, NPBCH and SIB. The data channel is a FHSS single carrier other than the anchor carriers if the 3N1 frame structure is used and the single narrowband carrier if the 3N2 frame structure is used. A NPDCCH or NPDSCH is received on a middle index anchor carrier or in the data segment. The NPSS overrides a TDD configuration indicated by the eNB.

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.
