A transmission power control method, system and transmission means

The present invention discloses a transmission power control method, system and transmission apparatus. The method comprises the steps of: a first transmission information transmitting power of the first signal for adjusting the acquisition; obtaining power of each working channel; The adjustment step, each of the working power of the first channel information and determine the need to adjust the work channel, to adjust the transmit power of the first transmission signal. By the above-described embodiment, the present invention enables adjustment of the transmission power of the first transmit signal, to avoid the automatic transmission power control means saturated, energy conservation.
