NON-REGENERATION RELAY COMMUNICATION SYSTEM

WIPO Patent Application WO/2024/034314

A1

[Problem] To provide a non-regeneration relay communication system with which non-regeneration relay communication using full-duplex communication is possible. [Solution] This non-regeneration relay communication system for performing non-regeneration relay communication between a first communication station and a second communication station via a relay station is characterised by comprising: a first delay calculation means which, on the basis of a signal, calculates a first signal-to-noise ratio in the communication between the first communication station and the relay station, and a first transmission delay indicating a delay in the communication between the first communication station and the relay station; a second delay calculation means which, on the basis of a signal, calculates a second signal-to-noise ratio in the communication between the second communication station and the relay station, and a second transmission delay indicating a delay in the communication between the second communication station and the relay station; and a communication determination means which performs the non-regeneration relay communication on the basis of the first signal-to-noise ratio, the first transmission delay, the second signal-to-noise ratio and the second transmission delay.
