Abstract: This document discusses, among other things, a wireless personal-area network (PAN) underlying a cellular wide-area network (WAN). The PAN includes a wearable user equipment (UE-W) and a user equipment aggregation node (UE-AN). The UE-W includes processing circuitry to process data for communication with a network of the WAN through the UE-AN, and radio interface circuitry to communicate with the UE-AN through a first air interface. The UE-AN includes processing to process data for communication between the network of the WAN and the UE-W, and radio interface circuitry to communicate with the network of the WAN through the first air interface and with the UE-W through a second air interface. The UE-W and the UE-AN can share a network credential, appearing as a single device to the WAN.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for determining availability of soft time-domain resources for a node in an integrated access and backhaul (IAB) network. In one aspect, a method includes receiving a Radio Resource Control (RRC) message from the IAB donor; determining, based on the RRC message, whether soft time-domain resources are available for the IAB node; and in response to determining that soft time-domain resources are available, scheduling a transmission with a child node using the available soft time-domain resources.

Abstract: A device of a New Radio (NR) evolved Node B (gNodeB), a method and a machine readable medium to implement the method. The method includes: processing a first signal sent by a NR evolved NodeB (gNodeB) regarding a primary physical random access channel (PRACH) configuration to be used to encode for transmission a first communication to the gNodeB; processing a second signal sent by the gNodeB regarding a secondary PRACH configuration different from the primary PRACH configuration and to be used to encode for transmission a second communication to the gNodeB; determining the primary PRACH configuration from the first signal and the secondary PRACH from the second signal; and switching from the primary PRACH configuration to the secondary PRACH configuration and encode for transmission the second communication to the gNodeB based on the secondary PRACH configuration.

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: 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: An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to a memory. To configure the IAB node for time-domain resource management within an IAB network, the processing circuitry is to detect that a time-domain resource assigned to a child communication link of the IAB node is available. An uplink message is encoded for transmission by a mobile terminal (MT) function of the IAB node to a parent IAB node. The uplink message indicates availability of the time-domain resource for a parent backhaul link between the IAB node and the parent IAB node. A downlink message from the parent IAB node is decoded. The downlink message is received via the parent backhaul link and using the time-domain resource.

Abstract: Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems include configuring one or more resources to allocate time-domain or frequency domain availability/utilization. Configurations of resources can be aligned between one or more nodes such that resource availability of a first node can be coupled to resources of a second node. Allocated resources can include uplink, downlink, and flexible resources. Allocated resources can be indicated as not available, hard, or soft resource types. A configuration pattern can indicate a sequence of time-domain resource or frequency domain resource availability of a DU in the IAB network.
