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.

Abstract: An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for resource allocation within an IAB network, the processing circuitry is to decode radio resource control (RRC) signaling from a central unit (CU) function of an IAB donor node. The RRC signaling configures first time-domain resources for a parent backhaul link between a mobile termination (M) function of the IAB node and a distributed unit (DU) function of a parent IAB node, and second time-domain resources for a child backhaul link between a DU function of the IAB node and a MT function of a child IAB node. Uplink data is encoded for transmission to the parent IAB node based on the first time-domain resources. Downlink data is encoded for transmission to the child IAB node based on the second time-domain resources.

Abstract: The present disclosure is directed to systems and methods for conveying remote interference management information via a reference signal. For example, an interference management method may include receiving, at a first device, an interference signal from a second device. At the first device, a reference signal is generated, including mitigation information for remote interference management. The first device may transmit the reference signal to the second device. The method may further include receiving, at the first device, a mitigation response signal indicative of a level of mitigation undertaken by the second device based on the mitigation information that the first device transmitted.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for random access channel (RACH) resource coordination. Some embodiments are directed to an apparatus in an Integrated Access and Backhaul (IAB) network. The apparatus includes processor circuitry and radio front circuitry. The radio front end circuitry can be configured to receive random access channel (RACH) resource configuration for communicating with a parent node and a child node. The processor circuitry can be configured to determine, based on the RACH resource configuration, a first RACH resource for communicating, in a half-duplex mode, with the parent node. The processor circuitry can be further configured to determine, based on the RACH resource configuration, a second RACH resource for communicating, in the half-duplex mode, with the child node, where the second RACH resource is orthogonal to the first RACH resource.

Abstract: An approach is described for a method for a base station in a fifth generation (5G) wireless c01mnunication or a new radio (NR) system that includes the following steps. The method includes determining base initial seeds and a time parameter. The method further includes generating actual initial seeds based on the base initial seeds and the time parameter; generating a Pseudo-Noise (PN) sequence based on one of the actual initial seeds; and generating a remote interference management reference signal (RIM-RS) sequence based on the PN sequence. The method further includes transmitting the RIM-RS sequence to a remote base station.

Abstract: Provided herein are systems and methods of configuring received signal strength indicator (RSSI) measurements to determine crosslink interferences (CLI). For instance, a user equipment (UE) can receive, using radio front-end circuitry, a RSSI resource configuration for CLI measurement from a base station in a 5G network. The UE can then measure a RSSI of one or more received signals based at least in part on the RSSI resource configuration. The UE can then perform one or more CLI measurements based at least in part on the measured RSSI. The RSSI resource configuration includes an identifier information element (IE), one or more slot-level indication IEs, one or more symbol-level indication IEs, one or more physical resource block (PRB)-level indication IEs, one or more resource element (RE) pattern indication IEs, and one or more receive beam indication IEs.
