Patent number: 10863445Abstract: A method for assigning downlink transmit power levels to radio nodes (RNs) in a small cell radio access network (RAN) includes assigning initial power levels to the RNs. For each cell, first events are counted indicating that UEs receiving a signal from their serving cells with a signal strength below a specified value have entered a coverage hole. For each cell, second events are counted indicating that UEs have re-established a previous connection on one of the cells. For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and, a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.Type: GrantFiled: April 14, 2020Date of Patent: December 8, 2020Assignee: Corning Optical Communications LLCInventors: Hithesh Nama, Cong Shen, Peter J.

Patent number: 10771338Abstract: Systems and methods are disclosed for managing an aggregated self-organizing network (A-SON). In such, a plurality of small cells is grouped into clusters using available topology information. In one implementation, a subset of clusters is assigned to groups of a first type, such that the clusters within a group of the first type have minimal RF connectivity. For example, scanning or updating of RF parameters may then be coordinated such that adjacent clusters do not scan or update simultaneously but clusters within groups of the first type do have at least partially overlapping scans or updates. Similarly, subsets of clusters may be assigned to first and second groups of a second type, such that the clusters within a first group of the second type have sufficient coverage to provide RF connectivity to clusters within the second group, if the second group encounters a service interruption. Other benefits are also described.Type: GrantFiled: November 27, 2018Date of Patent: September 8, 2020Assignee: Corning Optical Communications LLCInventors: Yashodhan A.

Patent number: 10648561Abstract: Piston rings are disclosed that relate to seal performance in piston containing machines such as piston driven engines. The piston rings may include a piston ring contact side for contact with a cylinder wall in which the piston ring contact side has multiple cavities configured on alternating edges of the piston ring contact side. Certain examples of these piston rings have cavities with an average depth that is less than 1/300th of the piston ring width and which collectively occupy a cavity area percentage of the piston ring contact side that is between 20% and 30% of the total area of the piston ring contact side.Type: GrantFiled: April 6, 2018Date of Patent: May 12, 2020Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventors: Michael Khonsari, Cong Shen

Method for signal transmission to multiple user equipments utilizing reciprocity of wireless channel
Patent number: 10236958Abstract: The present disclosure provides a method for transmitting a signal to multiple User Equipments (UEs) utilizing reciprocity of a wireless channel. In this method, a vector channel from the base station to each UE can be converted into an equivalent Single Input Single Output (SISO) channel having a strong Light-of-Sight (LOS) component using channel feedback. In this way, a reliable signal transmission to multiple UEs can be achieved with little channel training overhead. The present disclosure has prominent advantages such as simplicity in implementation, low processing complexity and very low channel training overhead and is particularly applicable in low-speed transmission of broadcast signaling in a massive MIMO system and scenarios where the base station is to page inactive UEs.Type: GrantFiled: March 21, 2016Date of Patent: March 19, 2019Assignee: University of Science and Technology of ChinaInventors: Wenyi Zhang, Cong Shen, Ning Liang -
