Patent number: 9848343Abstract: A method and system architecture for a self-organizing network (SON) includes a first cell having a first user equipment classifier for determining one of cell edge and cell central. The SON also includes a second cell having a second user equipment classifier for determining one of cell edge and cell central. The system architecture and method provide a first transmit time interval (TTI) schema for user equipment within the area of coverage associated with the first cell and a TTI schema for user equipment within the area of coverage associated with the second cell, the second TTI schema differing from the first TTI schema. The user equipment is classified as cell center or cell edge in dependence upon at least one of QoS requirement, geometry, periodic PSMM and CQI reports. The TTI schemas are used for “cell edge” user equipment by the respective cells.Type: GrantFiled: January 13, 2017Date of Patent: December 19, 2017Assignee: AIRHOP COMMUNICATIONS, INC.Inventors: Fei Frank Zhou, Hanson On, Zaijin Guan

Patent number: 7835315Abstract: An approach is provided for addressing in a multiple carrier communication system. In one embodiment, a group index is assigned to a group of terminals of a communication network. The group index permits sharing of addressing indices supported by the communication network for transmission of data to the group of terminals. In another embodiment, a plurality of terminals is classified using preamble indices corresponding to the terminals into one or more classes. A multi-user packet, which utilizes the preamble indices to activate only a class of the terminals for processing the multi-user packet, is generated.Type: GrantFiled: August 22, 2006Date of Patent: November 16, 2010Assignee: Nokia CorporationInventors: Zhouyue Pi, Zhigang Rong, Lin Ma, Fei Frank Zhou, Mark W.
