Patent number: 8655410Abstract: A method and apparatus for reducing signal interference within a cellular radio system to increase both coverage and capacity. The method and apparatus include altering the direction of beams within cell sectors is among discrete angular positions according to a predetermined, cyclic pattern. The predetermined, cyclic pattern varies in a group of adjacent cell sectors such that inter-cell interference is significantly reduced or eliminated by rotating at a different cycle the beams in adjacent cells. This discrete, angular movement of beams provides for downlink transmissions to be timed in such a way (i.e., scheduled) such that transmission to a user will occur in accordance with the beam and time slot having the best carrier to interference (C/I) ratio for that user.Type: GrantFiled: November 3, 2011Date of Patent: February 18, 2014Assignee: Apple, Inc.Inventors: Nimal Gamini Senarath, Yoon Chae Cheong, Shalini Periyalwar, Robert Matyas

Patent number: 7756520Abstract: A method and apparatus are provided for selecting an optimum base station for communicating with a terminal in a wireless communication system. A base station controller stores two candidate sets for each terminal within communication range of the base stations controlled by the base station controller. One candidate set lists base stations for which the channel quality of the uplink channel between the base station and the terminal is acceptable for communication. The other candidate set lists base stations for which the channel quality of the downlink channel between is acceptable for communication. This allows the base station controller to take into account the predominant direction of traffic when assigning base stations for communication with the terminal.Type: GrantFiled: October 17, 2001Date of Patent: July 13, 2010Assignee: Nortel Networks LimitedInventors: Bassam M.

Patent number: 7463616Abstract: The present invention keeps track of channel change indicia associated with wireless communications with mobile terminals, and bases the scheduling of data in time slots of a scheduling period on the channel change indicia. The channel change indicia may be derived from any information that bears on the rate at which channel conditions are likely to change, such as the velocity the mobile terminals are traveling or actual channel condition measurements. Preferably, mobile terminals associated with intermediate values for the channel change indicia are given priority, and thus, scheduled for transmission before those with lower and higher values. The invention is applicable to uplink and downlink communications, and is particularly beneficial when implemented in uplink and downlink schedulers in a base station.Type: GrantFiled: March 28, 2002Date of Patent: December 9, 2008Assignee: Nortel Networks LimitedInventors: Mark Earnshaw, Bassam M.
