Abstract: Some embodiments of this disclosure include apparatuses and methods for supporting integrated access and backhaul (IAB) networks. IAB nodes may be configured to broadcast in-raster and off-raster synchronization signal blocks (SSBs) for establishing communications with mobile devices and/or user equipment (UE). The SSBs may provide control resource set (CORESET) data used for establishing a communication channel between a UE and an IAB node. The CORESET data may be configured to support the broadcast of off-raster SSBs in wireless communication systems. In some embodiments, the in-raster SSB and the off-raster SSB may share the same CORESET. In this case, the IAB may modify a bit pattern of configuration table corresponding to the shared CORESET and broadcast the in-raster SSB and the off-raster SSB while including the modified bit pattern.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for remote interference management (RIM) in wireless networks, including RIM reference signals (RIM-RS) transmitted to assist victim radio access network (RAN) nodes to identify aggressor RAN nodes due to, for example, atmospheric ducting. The RIM-RS is also flexibly configured. Other embodiments may be described and/or claimed.

Abstract: Systems and methods of reducing control plane latency in a 5G IAB network are described. SRs transmitted between nodes indicate that a control plane PDU is to be transmitted. The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCD field in the MAC sub header of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant. The SR or RRC message can also specify a delayed timeslot for the grant. For contention-based procedures the RACH preamble is randomly selected or selected from among a set of RACH preambles assigned for RRC procedures.

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: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.

The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCID field in the MAC subheader of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant.

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: Provided herein are a method and an apparatus for interference measurement using a beam management reference signal (BM-RS). The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: decode one or more beam management reference signals broadcasted by a Transmission Reception Point (TRP) in a cell, wherein the one or more beam management reference signals are used by the TRP to perform beam management for respective one or more other UEs in the cell; and measure interference from the one or more other UEs in the cell based on the decoded one or more beam management reference signals. According to some embodiments, the overhead for the interference measurement can be reduced since it is not necessary to allocate a separate CSI-RS for the purpose of interference measurement.
