  • Method and apparatus for a sectored cell of a cellular radio communications system
    Patent number: 6167036
    Abstract: A nine-sectored cell (20) of a cellular radio communications system has three base transceiver stations (BTSs) colocated at its cell site (26). Each BTS is substantially independently coupled to a remote base station controller (BSC). Each BTS handles communications with subscriber units within a respective coverage area including three mutually-adjacent sectors (e.g. a1, b1, c1). When a subscriber unit moves between the coverage areas of different BTSs, a soft handoff is controlled by the BSC. When a subscriber unit moves between two sectors in the same coverage area, a softer handoff is implemented by the respective BTS.
