Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing full-dimension multi-input multi-output (FD-MIMO) and providing collision reduction by transmitting data to an evolved Node-B (eNB) on an uplink (UL) resource; and receiving an acknowledgement (ACK) or negative acknowledgment (NACK) on a physical HARQ-ACK indicator channel (PHICH), responsive to transmitting the data on the UL resource. The PHICH may be mapped to a least physical resource block (PRB) that is offset by a PHICH offset. The PHICH offset may include a group offset and a sequence offset relative to a transport block (TB) index and first PRB index of a corresponding uplink shared channel. Other embodiments are described.

Abstract: Technology described herein addresses symmetric uplink (UL)/downlink (DL) designs that can be applied to both uplink and downlink transmissions. A symmetric UL/DL design can define a Transmission Time Interval (TTI) format with control channels and data channels multiplexed using Frequency Division Multiplexing (FDM) or Time Division Multiplexing (TDM) to partition the control channels and the data channels within a Transmission Time Interval (TTI). A unified waveform can be applied to both UL and DL transmissions. Several Demodulation Reference Signal (DM-RS) designs are also described. A hybrid mode for UL transmissions is also described.

Abstract: This disclosure describes systems, methods, computer readable media, and/or apparatus related to encoding wireless communication preamble structures with cyclic redundancy check (CRC) that is performed on both a common part, as well as, station specific parts of a signaling field. The signaling field generated by this mechanism may be relatively shorter, resulting in less preamble overhead, than if a separate CRC was to be provided for each of the station specific parts, as well as the common part of the signaling field. In additional embodiments, tail bits may be provided for a combination of the common part of the signaling field and each station specific part of the signaling field. Compared to providing tail bits separately for the common part and each of the station specific parts, removing the tail bits from the common part may result in relatively less overhead of the preamble structure.

Abstract: Embodiments of a system and method for distributed channel access for device-to-device (D2D) communication in a wireless network are generally described herein. User equipment (UE) may transmit a connection identifier (CID) code at a beginning of a contention window to request channel access for a D2D transmission to a receiving device. Links for D2D transmissions from a transmitting device to a receiving device are identified by a CID that is mapped to a CID code. The UE may receive a bandwidth grant from the receiving device during the contention window, along with bandwidth grants for other CIDs, in an order based on a priority level of the CID. The UE may transmit data after reception of the bandwidth grants in time-frequency resources indicated in an associated one of the bandwidth grants. In some embodiments, spatial-reuse and variable resource size allocation are supported.
