Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for directional communication are generally described herein. The eNB may transmit, during a downlink sub-frame, a first beam refinement training signal and an uplink scheduling block to a first UE according to a downlink transmission direction from the eNB to the first UE. The eNB 104 may further transmit, during the downlink sub-frame, a second beam refinement training signal and a downlink scheduling block to a second UE according to a downlink transmission direction from the eNB to the second UE. The uplink scheduling block may indicate scheduled uplink resources for a scheduled uplink transmission by the first UE and the downlink scheduling block may indicate scheduled downlink resources for a scheduled downlink transmission to the second UE.

Abstract: Embodiments of a network User Equipment (nUE), wearable User Equipment (wUE), and methods for sidelink communication are generally described herein. The nUE may transmit a control channel that allocates a subframe as either a downlink subframe or an uplink subframe for a sidelink communication between the nUE and a wearable User Equipment (wUE). When the control channel allocates the subframe as a downlink subframe, the nUE may contend for access to channel resources. The contention may include transmission of a transmitter resources acquisition and sounding (TAS) channel in a physical resource block (PRB) and an attempted detection of a receiver resources acquisition and sounding (RAS) channel from the wUE in the PRB. When the control channel allocates the subframe as an uplink subframe, the wUE may contend for access to the channel resources.

Abstract: Embodiments of a system and method for dual connectivity for device to vehicle or vehicle to vehicle communication in a Wireless Network are generally described herein. In some embodiments, processing circuitry may determine a quality of service (QoS) level for data to be transmitted over a first radio access technology (RAT) connection and determine a QoS indicator from the QoS level, the QoS indicator identifying a dual connectivity backup transmission, the dual connectivity backup transmission including a hot, warm, or cold backup. In some embodiments, transceiver circuitry may attempt to transmit the data using a first transmission mode, the first transmission mode using the first RAT connection and the data including the QoS indicator and retransmit, in response to the attempt failing, the data using a second transmission mode.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.

Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.
