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: Systems and methods of adjusting contention window size (CWS) in a LBT procedure for both UL and DL unlicensed spectrum transmissions are described. The UE makes a HARQ-ACK determination for at least one code block group (CBG) of a transport block (TB) in a reference burst from a base station, determines whether the HARQ-ACK determination for the CBG meets a predetermined number of NACKs, transmits to the base station a single bit HARQ-ACK feedback for the TB that is dependent on whether the predetermined number of NACKs has been met, and receives or determines the adjusted CWS and uses the adjusted CWS for communication with the base station.

Abstract: Technology for an eNodeB to communicate with a user equipment (UE) using a self-contained time division duplex (TDD) subframe within a wireless communication network is disclosed. The eNodeB can process, for transmission to the UE, a DL self-contained time division duplex (TDD) subframe comprising an extended physical downlink shared channel (xPDSCH), an extended physical downlink control channel (xPDCCH), a downlink (DL) spacing signal, and a guard period, wherein the xPDSCH, the xPDCCH, the DL spacing signal, and the guard time are located within the DL self-contained TDD subframe prior to an extended physical uplink control channel (xPUCCH). The eNodeB can process, an uplink (UL) self-contained TDD subframe, received from the UE, having a UL spacing signal located after an extended physical uplink shared channel (xPUSCH).
