ABSTRACT:
A telecommunications system supports a variety of packet data services with throughputs ranging from low to high data rates. The system controls the user data transmission over a channel according to the user data throughput requirements of the application. By properly scheduling the time that particular transmission takes place, high data rate applications may be supported without the need for code aggregation, and low rate users may be supported without the requirement of multiple spreading factors. Base stations may transmit scheduling information to user devices in downlink time slots and user devices may transmit status information to base stations in uplink time slots.
