Method of performing anti-jamming techniques through antenna beam hopping in communication systems implemented by using plurality of relay and electronic apparatus thereof

A method for a first electronic apparatus to perform communication through a communication system implemented using a plurality of relays, the method comprising:

• determining a beam hopping pattern that is a pattern for changing a first relay, which is a relay used to transmit and receive data in relation to a second electronic apparatus and included in the plurality of relays, to another relay included in the plurality of relays;
• based on the beam hopping pattern, changing the first relay, which is a relay used to transmit and receive data in relation to the second electronic apparatus, to a second relay that is one relay among the plurality of relays;
• shaping a beam for communication with the second electronic apparatus through the second relay;
• aligning an antenna to transmit and receive data based on the shaped beam;
• and
• transmitting and receiving with the second electronic apparatus through the second relay, using the antenna,
• wherein the beam hopping pattern is shared with the second electronic apparatus,
• wherein the first electronic apparatus comprises a relay location tracking apparatus that obtains location information of the plurality of relays, and a beam shaping module that shapes the beam,
• wherein the first electronic apparatus controls at least one of the beam shaping module and the antenna based on the location information obtained through the relay location tracking apparatus and the beam hopping pattern,
• wherein the beam hopping pattern used to communicate with the second electronic apparatus and timing at which a beam hops according to the beam hopping pattern are shared with the second electronic apparatus, and
• wherein the first electronic apparatus determines one relay among the plurality of relays as the second relay based on the beam hopping pattern, and controls the beam shaping module in order to shape a beam based on at least one of an identifier of the second relay and location information of the second relay.
