Transmission power control method and device |
摘要 |
Disclosed is a method and an apparatus for controlling transmission electric power capable of minimizing a decrease in the amount of maximum transmission electric power without degrading an adjacent channel leakage power ratio when code-multiplexing additional control information with data and main control information. A mobile device checks values of gain factors ²d and ²c when performing code multiplexing to transmit signals from channels DPDCH to transmit data, DPCCH to transmit main control information, and HS-DPCCH to transmit additional control information. A maximum transmission electric power is decreased at a plurality of levels based on the check result and a ratio (”hs) between the gain factors ²c and ²hs. It may be preferable to check the presence or absence of transmission data instead of the gain factor ²d. In this case, when no transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on ”hs. When transmission data is available, the maximum transmission electric power is decreased at a plurality of levels based on the gain factor ²c and ”hs. |
