Publication number: 20240397505Abstract: Aspects of the technology described herein are directed towards using generic control information in a three-party wireless communication system to schedule a data transmission and reception of the data transmission. A scheduler node transmits the generic control information, comprising identification information that identifies a user equipment device as a transmitter node, and scheduling information that schedules a data transmission. For unicast data transmissions, the generic control information further identifies a receiver node, and can schedule transmission of an ACK/NACK from the receiver node corresponding to receiving the data transmission. A control procedure can be configured in a user equipment device by linking a channel configuration dataset to a resource configuration dataset, which in turn is linked to a channel transmit and receive configuration dataset. Reconfiguration is achieved by changing the linking(s) between one or more different available datasets.Type: ApplicationFiled: August 5, 2024Publication date: November 28, 2024Inventors: Xiaoyi Wang, Ralf Bendlin

Patent number: 12096455Abstract: The described technology is generally directed towards operating a user equipment node as a scheduler user equipment (e.g., which can be a local manager of other nodes in a group). The scheduler user equipment receives a scheduling request for the scheduling of the resources for transmission of data by a transmitter user equipment, and based on the traffic type requested, schedules the transmitter user equipment and receiver user equipment(s) with scheduling data/allocated radio resources. The transmitter user equipment can directly transmit to the receiver user equipment(s) on the allocated radio resources, e.g., without further involvement of the scheduler user equipment/local manager. For cellular data, the scheduler user equipment can schedule the transmitter user equipment to transmit to the scheduler user equipment as a receiver node.Type: GrantFiled: September 30, 2022Date of Patent: September 17, 2024Assignee: AT&T Intellectual Property I, L.P.Inventors: Xiaoyi Wang, Arunabha Ghosh, Andrew Thornburg, Thomas Novlan, Ralf Bendlin, Milap Majmundar

Patent number: 12035248Abstract: 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: GrantFiled: November 3, 2021Date of Patent: July 9, 2024Assignee: AT&T Intellect al P Property I, L.P.Inventors: Aditya Chopra, Arunabha Ghosh, Thomas Novlan, Andrew Thornburg, Xiaoyi Wang, Ralf Bendlin

Patent number: 11997041Abstract: An early termination system for blind decoding is provided to decrease the computational resources utilized when decoding the physical resources, and decrease the time spent decoding. A blind decoding priority list can be used by the mobile device to preferentially decode specific physical resource elements as it specifies the order of all the candidate physical downlink control channels (PDCCHs). When the physical resource elements are decoded, if there is no more downlink control information in that transmission time interval, the downlink control information can include a termination bit, and the mobile device, upon identifying the termination bit can cease blind decoding of the remainder candidates. In this way, the blind decoding process more quickly identifies the downlink control information, and subsequent blind decoding is halted.Type: GrantFiled: June 17, 2020Date of Patent: May 28, 2024Assignee: AT&T Intellectual Property I, L.P.Inventors: Xiaoyi Wang, Ralf Bendlin, Arunabha Ghosh, SaiRamesh Nammi
