  • Patent number: 8891636
    Abstract: In a wireless communication method, a first wireless communication apparatus transmits through a first wireless resource to a second wireless communication apparatus a first signal generated from a second signal for use in processing performed by the second wireless communication apparatus and a third signal for use in error checking of the second signal. The second wireless communication apparatus detects a second wireless resource to be used in the processing on the basis of the first signal, and performs the processing by using the second signal and the detected second wireless resource. For the detection, a section of the first signal corresponding to the second wireless resource is scrambled, or the first signal is scrambled with a scrambling sequence corresponding to the second wireless resource, or the bit order in at least part of the first signal is changed in a manner corresponding to the second wireless resource.
