Patent number: 11350485Abstract: The described technology is generally directed towards an autonomous topology management scheme in a wireless communications network that establishes a hierarchical structure from a peer-to-peer network without assistance from the wireless network. A group of user equipments negotiate with each other to elect a local manager that acts as a base station by which other user equipments of the group can access network resources. Described is an example voting scheme by which the negotiation process elects the local manager for a term.Type: GrantFiled: February 5, 2020Date of Patent: May 31, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Xiaoyi Wang, Thomas Novlan, Andrew Thornburg, Milap Majmundar, Arunabha Ghosh

Publication number: 20220140870Abstract: Various embodiments disclosed herein provide for an enhanced timing advance scheme to support MU-MIMO in an integrated access and backhaul system. The timing advance scheme disclosed herein aligns the arrival time between backhaul links and access links to enable MU-MIMO gain at the receiver side. In the integrated access and backhaul system, which comprises distributed nodes, the timing advance offset for an access link transmission (a transmission to a node further away in hops from the core network, or to a user equipment device) can be modified by offsetting it with the timing advance of the backhaul link (e.g., from a parent node). This enables the arrival time for transmissions, both access link transmissions from the UE or child node, and backhaul link transmissions from a parent node to arrive at the same time.Type: ApplicationFiled: January 14, 2022Publication date: May 5, 2022Inventors: Xiaoyi Wang, Thomas Novlan, Salam Akoum, Ralf Bendlin, Milap Majmundar, Andrew Thornburg, Arunabha Ghosh

Publication number: 20220060995Abstract: Various embodiments disclosed herein provide for a power control system in a multi-hop integrated access and backhaul network. In the 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 can manage the power levels of the relay node in order to reduce the difference in power levels. The power control system can schedule relay node devices to transmit uplink transmissions alongside user equipment devices that have a high signal strength; schedule relay nodes and user equipment devices to separate symbols within a time slot; and/or perform closed loop power control management at the relay node to reduce the power level for an uplink transmission.Type: ApplicationFiled: November 3, 2021Publication date: February 24, 2022Inventors: Aditya Chopra, Arunabha Ghosh, Thomas Novlan, Andrew Thornburg, Xiaoyi Wang, Ralf Bendlin

Publication number: 20210352566Abstract: An enhanced handover procedure is provided to facilitate communication routing changes in an integrated access and backhaul (IAB) network. In an IAB network a network node can be connected to the core network via multiple different paths, and when the path changes, (e.g., when an intermediate network node performs a handover procedure with another network node), messages can be sent to relevant network nodes informing them of the route change so as to reduce the number of protocol data units (PDUs) that are transmitted to network nodes that are no longer part of the communication path to the target network node. The network node that is no longer part of the communication path can also inform a parent node of which PDUs have been successfully transmitted to the target network node so that the parent node can retransmit the PDUs that were not transmitted successfully.Type: ApplicationFiled: July 20, 2021Publication date: November 11, 2021Inventors: Milap Majmundar, Andrew Thornburg, Thomas Novlan

Publication number: 20210289479Abstract: To increase network efficiency, a user equipment (UE) can be appointed as a local manager to coordinate the allocation of resources used by other UEs. For example, the network can promote the UE as a local manager and assign the local manager a resource pool. The local manager can then broadcast synchronization signals to let the other UEs associate themselves with the local manager. After the other UEs are synced with the local manager, the local manager can allocate resources to the other UEs. Based on report data regarding the local managers management procedures, the network can maintain the UE as the local manager or demote the UE from local manager status.Type: ApplicationFiled: May 28, 2021Publication date: September 16, 2021Inventors: Xiaoyi Wang, Ralf Bendlin, Arunabha Ghosh, Andrew Thornburg, Salam Akoum, Thomas Novlan, Milap Majmundar
