Abstract: Embodiments of latency reduction for wireless data transmission are generally described herein. A user equipment (UE) identifies a shortened transmission time interval (xTTI) length configuration for a time division duplexing (TDD) component carrier (CC), the xTTI length configuration comprising a length in time or a length in orthogonal frequency division multiplexing (OFDM) symbols. The UE identifies scheduling timing and hybrid automatic repeat request (HARQ) timing of physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) on the TDD CC based on the identified xTTI length configuration. The UE signals for transmission of a HARQ acknowledgement (HARQ-ACK) based on the identified xTTI length configuration.

Abstract: Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.

Abstract: Described is an apparatus of an Evolved Node-B (eNB) comprising a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to generate a reference signal transmission for an eNB Transmitting (Tx) beam corresponding with at least a first eNB antenna port having a first polarization and a second eNB antenna port having a second polarization. The second circuitry may be operable to process one or more reporting transmissions carrying at least one of a first signal reception indication for a first UE antenna port and a second signal reception indication for a second UE antenna port. The third circuitry may be operable to determine a transmission hypothesis based upon the one or more reporting transmissions.

Abstract: Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.

Abstract: Embodiments herein may relate to transmission, in a first physical channel transmission, of an indication of a first set of parameters related to a control channel; and transmission, in a control channel transmission using the first set of parameters, of an indication of a second set of parameters related to the control channel. Further embodiments may relate to identifying a first parameter related to interleaving REGBs of a PDCCH transmission, wherein the first parameter is selected from a first plurality of parameters; interleaving the REGBs based on the first parameter to form a CCE, and transmitting die CCE in the PDCCH transmission. Other embodiments may be described and/or claimed.

Abstract: Technology for a user equipment (UE) operable to decode a resource mapping pattern of a phase tracking reference signal (PT-RS) received from a base station in a wireless network is disclosed. The UE can decode control signaling received in a downlink from the base station. The control signaling can indicate a resource mapping pattern for a PT-RS. The UE can identify the resource mapping pattern for the PT-RS based on the control signaling received from the base station. The UE can encode one or more PT-RS for transmission to the base station in an uplink in accordance with the resource mapping pattern for the PT-RS.

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 x 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.
