    摘要: 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) for transmitting uplink transport channel data is determined. A combination of a spreading factor and a modulation scheme for uplink channel data transmission, corresponding to the determined TBS, is selected according to transmittable physical channel data bit sizes and puncturing limit values. The TBS is transmitted by incorporating it into control information of the uplink transport channel data. The modulation scheme and spreading factor combination 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 signaling overhead required to transmit E-DCH control information.

    摘要: Disclosed is a power setup method for minimizing a delay time caused by an HARQ of an E-DCH when an MAC-e PDU comprising scheduling information required for using a Node B controlled scheduling is transmitted in environments supporting a packet data service through the E-DCH in an asynchronous code division multiple access (CDMA) communication system. A user equipment (UE) generates packet data for transmitting through the E-DCH, determines if signaling information is included in Quality of Service (QoS) of the packet data and the packet data, sets a power gain preset according to each QoS of the packet data, applies a determined offset value to the set power gain when the signaling information is included in the packet data, and transmits the packet data through the E-DCH according to the power gain to which the offset value has been applied.
