摘要
The present disclosure relates to a transmission power control method and device capable of dynamically selecting optimal transmission power for the nodes in wireless network considering its surrounding interference. An embodiment comprises calculating a reduced transmitted power which will cause a corresponding reduced received power, such that: (a) transmitter interface and receiver interface can maintain connectivity of the active link with the reduced transmitted power, in the antenna direction between transmitter interface and receiver interface; (b) the reduced transmitted power does not create additional link-interference edges from any other active link, even if the transmission power of the other active link is maintained, in the antenna direction between the transmitting interface of the other active link and the receiver interface; and (c) the reduced transmitted power does not create additional hidden nodes, such that a CSRange of the reduced transmission power is still sufficient to inhibit transmission by any other interfering network node interface, in the antenna direction between said any other interfering network node and the receiver interface.
