Abstract
A transmission power management device including: a memory, and a processor coupled to the memory and configured to: acquire a first path loss between a first relay station and a second relay station, the first relay station relaying a first signal, the second relay station relaying a second signal, and adjust a first transmission power of the first signal by the first relay station based on the first path loss.
Claims21
A transmission power management device comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- acquire a first path loss between a first relay station and a second relay station, the first relay station being configured to relay a first signal transmitted from a first transmission device to a first reception device via the first relay station, the second relay station being configured to relay a second signal transmitted from a second transmission device to a second reception device via the second relay station, a period and a frequency of the first signal between the first relay station and the first reception device being substantially the same as a period and a frequency of the second signal between the second transmission device and the second relay station,
- acquire a gain of the second relay station,
- acquire a second path loss between the second relay station and the second reception device, and
- set a first transmission power of a first signal transmitted from the first relay station to the first reception device, wherein:
- a first reception power of the second reception device is determined based on the first transmission power, the first path loss, the gain and the second pass loss, and
- the first transmission power is set so that the first reception power is under a threshold value.
