Abstract:
A method of communicating information in a wireless cellular communication system, the method comprising the step of:communicating information between a plurality of subscriber units of the system and a base station in a cell of the system over at least one of an uplink and a downlink, wherein communications on the uplink are separated from communications on the downlink using code division duplexing; wherein communications between the base station and at least a subset of the plurality of subscriber units in the cell are separated using a code division multiple access technique; and wherein each of the subscriber units within a given antenna beam associated with a given sector of the base station is assigned a distinct beam-specific spreading code, the beam-specific spreading code being used in conjunction with a sector-specific spreading code to separate the communications between the base station and the subscriber units within the given antenna beam in accordance with the code division multiple access technique.
