Method and apparatus for determining transport parameters for physical layer to provide uplink packet data service in a mobile communication system

摘要

A method and apparatus for determining a spreading factor (SF) of a physical layer and number of bits for a physical channel in order to support a transport format combination (TFC) of an uplink dedicated channel in data transmission on the uplink dedicated channel in a mobile communication system are provided. A parameter decider selects, among available physical channel bit sizes, a bit size that minimizes bit repetition and does not require an additional physical channel. Accordingly, the hardware resources of a receiver are efficiently utilized.
