Transmitting data from a mobile station on an uplink in a spread spectrum cellular system

The present invention provides a method and an apparatus for a wireless communication between at least one mobile station and a base station in a cellular system. The method comprises providing a desired spreading in time and frequency domains to transmit data using at least two carriers in a transmission on an uplink to the base station.

In a spread spectrum cellular system, a base station sector may assign some transmission slots for a non-orthogonal transmission and other transmission slots for an orthogonal transmission to at least one mobile station, for example, in an uplink transmission. At the same time, for example, a base station sector may assign both modes to different mobile stations during the same time slot. By selectively using time and frequency or code division multiplexing, the mobile station may reduce interference, or alternatively, introduce minimal interference associated with multiple mobile stations transmitting data simultaneously at a base station sector. The reduced interference may enhance aggregate throughput of the uplink.
