Abstract:
Communication operations are optimally conducted by applying space-division multiple access in which wireless resources on a spatial axis are shared among a plurality of users. By applying an RD protocol to a communication system that conducts space-division multiple access, spatially multiplexed frames in a TXOP are made more efficient. By specifying a frame length for reverse direction frames with reverse direction permission information and having respective transmitters of reverse direction frames make their frame lengths uniform while respecting the specification, AGC operation stabilizes. Also, a transmit start time for reverse direction frames can be specified by reverse direction permission information, and respective transmitters of reverse direction frames can transmit frames at the same time while respecting the specification.

Claim (Index 1):
A communication apparatus, comprising:\n circuitry configured to:\n generate a plurality of media access control (MAC) information fields that include reverse direction permission information which indicates that reverse direction frame transmission is permitted, wherein the reverse direction permission information is included in one or more of the plurality of MAC information fields to be sent in a first burst, and the one or more of the plurality of MAC information fields that include the reverse direction permission information are addressed to a plurality of communication apparatuses; \n multiplex and transmit the plurality of MAC information fields in the first burst to the plurality of communication apparatuses; and \n receive, in a second burst, respective response frames that obey the reverse direction permission information from respective communication apparatuses of the plurality of communication apparatuses, \n wherein frame lengths of the response frames are the same for each of the plurality of communication apparatuses.
