1. A communication apparatus comprising:
a receiver, which, in operation, receives a frame including a Scrambler Initialization field and an Address field;
control circuitry, which, in operation, calculates an address value by dividing a plurality of bits that form a MAC address of the communication apparatus into a plurality of words, scrambling each of the plurality of words by using a value of the Scrambler Initialization field in the received frame as a seed, applying Cyclic Redundancy Check (CRC) encoding to a consecutive concatenation of the plurality of scrambled words, and taking upper bits of a bit sequence generated by the CRC encoding; and
a transmitter, which, in operation, transmits a response frame in response to the calculated address value matching a value of the Address field.
