  • Dynamic sectors in a wireless communication system
    Patent number: 8670778
    Abstract: A method for dynamic sector creation is disclosed. The method may include determining that a first sector of a cell is overloaded. The method may also include creating a second sector within the first sector. The method may further include transferring one or more mobile stations from the first sector to the second sector.
    Type: Grant

    Date of Patent: March 11, 2014
    Assignee: Qualcomm Incorporated
    Inventors: Jie Si, Rilun Tang, Syed Nadeem Ahsan
  • Data throughput improvement in IS2000 networks via effective F-SCH reduced active set pilot switching
    Patent number: 7783312
    Abstract: Systems and methods for improving the performance of wireless telecommunications networks by reducing data communications between a mobile station and a base station. One embodiment of the invention is implemented in an IS2000 (cdma2000) network. This network communicates data from a base station to a mobile station over a supplemental forward channel. In order to maintain the best communication channel for data transmissions, the mobile station monitors the signals received from an active set of base stations and identifies the strongest signal of a reduced active set so that the corresponding base station can be selected for data communications. Upon the occurrence of conditions indicating that a new base station within the reduced active set should be selected, the mobile station provides a notification to the base stations in the reduced active set so that further data transmissions will be made by the newly selected base station.
