Abstract  Abstract

The present invention relates to an uplink packet data service method and apparatus for an E-DCH in an asynchronous WCDMA system. The method of the present invention includes determining a transport block size (TBS) for transmitting uplink transport channel data, and transmitting the uplink according to the transmittable physical channel data bit sizes and a plurality of preset puncturing limit values. Selecting a combination of a modulation scheme (MF) and a spreading index (SF) corresponding to the determined transport block size for transmission of channel data, and putting the transport block size in control information on the uplink transport channel data It characterized in that it comprises a process of transmitting. Here, the combination of MF / SF is physical channel data that maximizes transmission efficiency and minimizes the number of punctured bits without requiring an additional physical channel in transmitting the uplink transport channel data of the transport block size. It depends on the bit size. The present invention has the effect of maximizing uplink transmission efficiency, saving transmission resources and reducing signaling overhead required for transmitting control information of the E-DCH.
