Abstract

An embodiment of the invention discloses a method, a device and equipment for determining transmitting power. The method for determining the transmitting power includes determining a gain factor of an enhanced dedicated channel dedicated physical data channel (E-DPDCH) under a compression mode according to the number of code channels required by first transmission of data; and determining the transmission power of the E-DPDCH according to the gain factor of the E-DPDCH under the compression mode. The method, the device and the equipment for determining the transmitting power determines the gain factor of the E-DPDCH under the compression mode according to the number of coded channels required by the first transmission of the data and achieves accurate determination of the gain factor of the E-DPDCH under the compression mode, therefore the transmission power of the E-DPDCH is determined according to the gain factor, waste of the transmission power of the E-DPDCH is reduced, and system capacity is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and equipment for determining transmission power. Background technique [0002] In WCDMA (Wideband Code Division Multiple Access) system, the required transmission of E-DPDCH can be obtained according to the gain factor of E-DPDCH (Enhanced Dedicated Channel Dedicated Physical Data Channel, enhanced dedicated channel dedicated physical data channel) power. Among them, a method for calculating the gain factor of E-DPDCH is to use an extrapolation formula for calculation, using one reference E-TFC (E-DCH Transport Format Combination, enhanced dedicated channel transmission format combination). The calculation formula is shown in formula (1), [0003] β ed , i , harq = β ed , ref L e , ref L e , i K e , i K e , ref · 10 ( Δharq 20 ) - - - (...
