Publication number: 20230254004Abstract: Embodiments for port reconfiguration for passive intermodulation interference mitigation are presented herein. A base station device comprises a signal processing component comprising a passive intermodulation interference component and an antenna configuration component. The passive intermodulation interference component determines passive intermodulation interference corresponding to uplink signals that have been received, via a configurable cellular antenna array of the base station device, from respective wireless devices of a group of wireless devices that have been communicatively coupled to the base station device. The antenna configuration component selects a defined configuration of a group of cellular antenna ports of the configurable cellular antenna array to facilitate a reduction of the passive intermodulation interference corresponding to the uplink signals.Type: ApplicationFiled: April 12, 2023Publication date: August 10, 2023Inventors: Ernest Tsui, Michael Taylor, Weihua Ye, Young Suh, Paul Maxwell, Guanying Ru, James Hollister

Patent number: 11463335Abstract: A network analysis and management system includes a processor coupled to a communications interface and a non-transitory memory. The processor is configured to read instructions from the non-transitory memory to cause the system to perform operations comprising receiving log data associated with communication between a first user device and a network using a first protocol stack including a plurality of layers. A plurality of network events are generated based on the log data. Each network event is associated with a respective log data entry of the log data and a respective layer of the plurality of layers. First network analysis information is generated by correlating first and second network events using a correlation configuration associated with a network management task. A network management message is generated using the first network analysis information, and transmitted to one of the first user device and the network for performing the network management task.Type: GrantFiled: January 13, 2020Date of Patent: October 4, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Helen Zeng, Guanying Ru, Srikanth Hariharan

Publication number: 20220132336Abstract: The described technology is generally directed towards jointly optimizing coverage, capacity, and layer balance in a wireless communications network while maintaining cell edge use device performance constraints. Aspects comprise monitoring edge user devices for performance information, and modifying the network based on the performance information, including jointly optimizing by changing antenna parameter data, layer balancing, handover biasing per cell neighbor pair, modifying scheduling priorities, and optimizing sector face harmonic throughput. Balancing uplink and downlink coverages are considered in the joint optimization. Further, interference is detected, predicted (as needed) and mitigated.Type: ApplicationFiled: January 3, 2022Publication date: April 28, 2022Inventors: Ernest Tsui, Guanying Ru, Rennie Archibald, Weihua Ye
