Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE), and methods for flexible duplex communication are generally described herein. The eNB may transmit a downlink control information (DCI) block to the UE during a group of time-division duplex (TDD) sub-frames. The eNB may further receive an uplink control information (UCI) block from the UE during the group of TDD sub-frames. A first candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and an uplink control portion. A second candidate flexible duplex format for the TDD sub-frames may include a downlink control portion and may exclude uplink control portions.

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: Downlink control information techniques for wireless communications with shorter TTI (S-TTI) length are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode signaling indicating a duration of a time window, the time window comprising a plurality of S-TTIs forming a single TTI. Absence of a discontinuous reception (DRX) indicator is detected within control information received within a first S-TTI of the plurality of S-TTIs. Upon detecting the absence of the DRX indicator within received control information, a S-PDCCH within each of the plurality of S-TTIs is monitored during the duration. Scheduling information received via the S-PDCCH within one of the plurality of S-TTIs is decoded, and data is encoded for transmission on a shared data channel based on the scheduling information.

Abstract: Techniques, apparatus and methods are disclosed that enable reduced signaling overhead in a fifth generation (5G) wireless system. The system includes support for asynchronous uplink transmission, resource pool configuration, acknowledgement response and retransmission. For example, in a Type-1 transmission scheme, a user equipment (UE) selects one resource within the resource pool and transmits data in the uplink on the selected resource. In a Type-2 transmission scheme, a UE selects one resource within a scheduling request (SR) region in the resource pool, transmits the SR for the resource which contains the resource allocation for data transmission, and transmits the uplink data on the resource which is indicated in the SR information. In a Type-3 transmission scheme, a UE selects a resource within the SR region, transmits the SR on the selected resource with information on the resource selected for subsequent data transmission and transmits on the indicated resource if it receives an acknowledgment, in response to its transmitted SR.

Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.
