Communication apparatus, communication method, and communication system

摘要

A physical frame is constructed, the physical frame including a medium access control super-frame payload which in turn includes a plurality of medium access control frames. With respect to the constructed physical frame, virtual carrier sense information is set in the plurality of medium access control frame so that a result of carrier sense is identical to another by virtual carrier sense based on the plurality of medium access control frames in the medium access control super-frame payload. The physical frame in which the virtual carrier sense information has been set is transmitted to a destined communication apparatus.

主权项

1. A terminal, comprising:
a plurality of antennas; circuitry coupled to the plurality of antennas and configured to:
receive a first physical frame, via the plurality of antennas, comprising a first physical header and first MAC frames, the first physical header comprising a first header for a first protocol and a second header for a second protocol, the second header following the first header, the first header comprising information related with a length of the first physical frame, each of the first MAC frames comprising a frame control field, a duration field, a destination address field, a data field, and a frame check sequence field, wherein values of duration fields of the first MAC frames are same, and addresses of destination address fields of the first MAC frames are same, andtransmit, via the plurality of antennas, a second physical frame comprising a bit map in response to a reception of at least one of the first MAC frames, the bit map comprising values of one or zero corresponding to a reception status of a MAC frame.
