1. A communication apparatus comprising:
an antenna, which, in operation, receives a sounding signal; and
circuitry, which, in operation, generates a first frame based on the sounding signal,
wherein the antenna, in operation, transmits the first frame containing first beamforming feedback information and a first channel quality indicator of the sounding signal, the first frame being transmitted with a second frame containing second beamforming feedback information and a second channel quality indicator by a multiuser transmission, wherein the first frame is different from the second frame,
wherein the multiuser transmission is performed over a plurality of communication links including a first communication link and a second communication link,
the first beamforming feedback information and the first channel quality indicator correspond to the first communication link, and the second beamforming feedback information and the second channel quality indicator correspond to the second communication link, and
the first frame does not contain the second beamforming feedback information and the second channel quality indicator, and the second frame does not contain the first beamforming feedback information and the first channel quality indicator.
