Abstract: To facilitate signal alignment for an integrated access backhaul (IAB) node, a system can determine a subset of beams that can be used for communication transmissions. Based on a signal quality associated with the subset of beams, the system can indicate that the subset of beams is to be used for the communication transmission. Consequently, the subset of the beams or another subset of the subset of the beams can be utilized for the communication transmission based on the signal quality of the beams.

Abstract: Dynamic frame structure coordination is performed between a parent integrated access and backhaul (IAB) node and child IAB node based on one or more multiplexing options. The parent node sends a dynamic frame structure coordination (DFSC) message to an IAB user equipment function of a child node, indicating that resources are available or released, overriding a semi-statically coordinated and configured downlink/uplink resource pattern. The parent node can make, or the child node can request, the modification. The DFSC message includes multiplexing option(s). The child IAB node's user equipment function communicates the frame structure update to the child node's distributed unit function, which allows the distributed unit function to utilize those resources in accordance with the multiplexing option. Half-duplex, full duplex, frequency division multiplexing and spatial division multiplexing capabilities are considered when selecting the multiplexing option or options for one or more slots identified in the DFSC message.

Abstract: The described technology is generally directed towards dynamic resource coordination that supports multi-hop based relaying for integrated access and backhaul (IAB) in New Radio (5G). Described is a technology in which an IAB node and a serving parent node use wireless signaling to dynamically adapt downlink and uplink resources used for access and backhaul links. An IAB node receives scheduling data from a parent node, configures a frame structure comprising mobile termination function subframes and distributed unit component subframes, and communicates data based on the frame structure. The parent node explicitly or implicitly indicates that a portion of the scheduling data is adaptable, e.g., sends a dynamic frame structure coordination message. In response, the IAB node can adapt the frame structure into a modified frame structure and can communicate further data based on the modified frame structure.

Abstract: The same or similar physical signals can be used for both user equipment (UE) and an integrate access backhaul (IAB) node. Different configurations of the resources and/or transmission periods of the signals can be used for initial access for access UEs and IAB nodes. In addition, to support topology formation, mobility/multi-connectivity procedures, and backhaul link management, periodic measurements and reports can be configured by a parent IAB node to a child IAB node UE function. This can comprise radio resource management (RRM), radio link monitoring (RLM), and beam management (L1-BM) measurements and reports.

Abstract: Facilitating a time-division multiplexing pattern-based solution for a dual-subscriber identity module with a single radio in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise obtaining, by a network device comprising a processor, multiple time-division multiplexing patterns applicable to a mobile device. The multiple time-division multiplexing patterns indicate respective repeating patterns of an on state and an off state of a defined identity of the mobile device. The method also can comprise facilitating, by the network device, a transmission, to the mobile device, of information indicative of the multiple time-division multiplexing patterns. In an example, the mobile device can be configured to operate with at least two subscriber identity modules.

Abstract: Various embodiments disclosed herein provide for power control system in a multi-hop integrated access and backhaul network. In a multi-hop integrated access and backhaul network a donor node can communicate with user equipment devices and relay nodes that have varying power levels, and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system disclosed herein can manage the power levels of the relay node in order to reduce the difference in power levels. In one embodiment, the power control system can schedule relay node devices to transmit uplink transmissions alongside UE devices that have a high signal strength. In another embodiment, the power control system can schedule relay nodes and UE devices to separate symbols within a time slot. In another embodiment, the power control system can perform closed loop power control management at the relay node to reduce the power level for the uplink transmission.

Abstract: Integrate access and backhaul (IAB) nodes can multiplex access and backhaul links in time, frequency, or space, which includes the transmission of signals and/or channels utilized as part of initial access and measurements used for radio resource management (RRM). The same physical layer signals and channels used for these purposes by access a user equipment device can be reused for performing similar procedures at the IAB node. Consequently, the IAB node can leverage various muting patterns to employ the use of half-duplex and full-duplex synchronization signal block radio resource management such that mobile terminal functionality and distributed unit functionality of the IAB node can receive and transmit signals simultaneously.
