Abstract: An apparatus is disclosed for determining a gain factor of an E-DPDCH in a compressed mode. In disclosure, the E-DPDCH gain factor in the compressed mode is determined according to the number of E-DPDCHs used for initial transmission of data. With the determined E-DPDCH gain factor, the transmission power of the E-DPDCH can be accordingly determined. As the E-DPDCH gain factor in compressed mode is determined according to the number of the E-DPDCHs for initial transmission of data, the gain factor of the E-DPDCH in compressed mode can be determined accurately, and thus the transmit power of the E-DPDCH can be determined accurately according to the E-DPDCH gain factor in the compressed mode. Therefore, the waste of transmit power of the E-DPDCH is reduced, and thus the system capacity is improved.
