1. A reception apparatus, comprising:
a receiver which, in operation, receives a signal that includes a legacy preamble, a non-legacy preamble and a data field, wherein the non-legacy preamble comprises a first non-legacy signal (SIG-A) field and a second non-legacy signal (SIG-B) field, the SIG-B field comprising a first channel field that corresponds to a first frequency subband and a second channel field that corresponds to a second frequency subband different from the first frequency subband, wherein the SIG-A field comprises a SIG-B compression subfield and a number of SIG-B symbols subfield, wherein
the number of SIG-B symbols subfield is indicative of a number of Multi-User (MU) Multiple-Input and Multiple-Output (MIMO) users when the SIG-B compression subfield indicates that a full bandwidth is allocated for MU MIMO transmission; and
a processor which, in operation, decodes the received signal,
wherein each of the first channel field and the second channel field includes a common field that carries resource assignment information when the SIG-B compression subfield indicates that the full bandwidth is not allocated for the MU MIMO transmission.
