Abstract  Abstract

Disclosed is a method and apparatus for providing uplink packet data services through an E-DCH in an asynchronous WCDMA system. A transport block size (TBS) of uplink transport channel data is determined. A combination of a spreading factor (SF) and a modulation format (MF) for uplink channel data transmission corresponding to the determined TBS is selected according to transmittable physical channel data bit sizes and predetermined puncturing limit values. The TBS is transmitted by incorporating it into control information of the uplink transport channel data. The combination of SF and MF is determined based on a physical channel data bit size that maximizes transmission efficiency and minimizes the number of punctured bits without requiring an additional physical channel in transmitting the uplink data having the TBS. This method maximizes uplink transmission efficiency to save transmission resources and reduces uplink signaling overhead required to transmit E-DCH control information.
