  • Communication system, relay station, and mobile station that perform relay communication and direct communication
    Patent number: 11510125
    Abstract: When a second mobile station detects quality deterioration of a signal received from a first mobile station at a second frequency, the second mobile station transmits a quality deterioration notification to a relay station at a first frequency. Upon receiving the quality deterioration notification, the relay station transmits a response at the second frequency to the second mobile station that has transmitted the quality deterioration notification, receives a signal from the first mobile station, and transmits the received signal to the second mobile station at the first frequency. Upon receiving the response from the relay station, the mobile station changes the communication mode so as to receive a signal that is from the first mobile station from the relay station.
