Abstract

The embodiment of the invention discloses a method, a device and equipment for determining transmitted power. The method for determining the transmitted power comprises the following steps of: determining a gain factor of an enhanced dedicated channel dedicated physical data channel (E-DPDCH) in a compressed mode according to the number of code channels required by the first transmission of data; and determining the transmitted power of the E-DPDCH according to the gain factor of the E-DPDCH in the compressed mode. According to the embodiment of the invention, the gain factor of the E-DPDCH in the compressed mode is determined according to the number of the code channels required by the first transmission of the data, so that the gain factor of the E-DPDCH in the compressed mode can be accurately determined; and the transmitted power of the E-DPDCH is further determined according to the gain factor, so that the transmitted power waste of the E-DPDCH is reduced, and the system capacity is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and equipment for determining transmission power. Background technique [0002] In WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) system, according to the gain factor of E-DPDCH (Enhanced Dedicated Channel Dedicated Physical Data Channel, Enhanced Dedicated Channel Dedicated Physical Data Channel), the emission required by E-DPDCH can be obtained power. Wherein, one calculation method of the gain factor of the E-DPDCH is to use an extrapolation formula for calculation, and use 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 ...
