ABSTRACT:
A wireless communication device, method and system adapted so that, in response to a repeat request indicating a communication signal (because of an error in transmission of the communication signal), the communication signal is wirelessly retransmitted using a remapping of bits into at least partially different frequencies in the retransmission compared to the original transmission.
