Method and apparatus for quantum computing based resource allocation in wireless communication system

An apparatus of a wireless communication system, the apparatus comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station via the transceiver, first information on interference among a plurality of terminals that are to receive a resource allocation from the base station, second information on a number of resources available for the plurality of UEs terminals, and third information on a reward matrix indicating a resource preference for the plurality of terminals,
• identify a plurality of qubits based on the first information and the second information,
• generate a preference matrix based on the reward matrix, the preference matrix indicating an iteration number of a quantum search algorithm with preference and being applied for each qubit of the plurality of qubits,
• select a quantum state from a superposed quantum state of the plurality of qubits, based on the quantum search algorithm with preference and the preference matrix,
• generate resource allocation information based on a measurement of the selected quantum state,
• determine whether a reward value corresponding to the resource allocation information exceeds a predetermined threshold value,
• in response to the reward value not exceeding the predetermined threshold value, resume the quantum search algorithm by multiplying a natural number to the preference matrix, and
• in response to the reward value exceeding the predetermined threshold value, transmit, to the base station via the transceiver,
• the resource allocation information.
