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 for efficient distributed scheduling is provided using tentative grants. A UE can receive a transmission request from a Tx UE, and from additional Tx UEs. Each Tx request can include a priority level of the transmitter UE sending the transmission request, to form a priority list. An incompatible list can be formed based on a signal to interference ratio of each transmitter with the UE. A grant message and the incompatible list can be transmitted for n−1 iterations from selected UEs based on the priority list and incompatible list. A tentative bandwidth grant can then be transmitted at an nth iteration to tentatively allow the transmitter UE to send a D2D communication to the UE in the bandwidth grant.

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.
