FIELD: radio engineering, communication.
SUBSTANCE: described is a method and an apparatus for determining transmit power. The method of determining transmit power involves: determining an enhanced dedicated channel dedicated physical data channel (E-DPDCH) gain factor in compressed mode according to the number of code channels required for initial transmission of data; and determining transmit power of E-DPDCH according to the E-DPDCH gain factor in compressed mode. The E-DPDCH gain factor in compressed mode is determined according to the number of code channels required for initial transmission of data in versions of the present invention, such that the E-DPDCH gain factor in compressed mode is determined accurately; furthermore, the transmit power of E-DPDCH is determined according to the gain factor.
EFFECT: reducing excessive consumption of transmit power of E-DPDCH and therefore the increasing system capacity.
