1. A wireless communication device, comprising:
a transmitter configured to transmit a first physical packet, the first physical packet including a first field and a plurality of second fields,
wherein the first field contains information for specifying a plurality of wireless communication terminals,
wherein the second fields are multiplexed and transmitted at least in any one of frequency multiplexing or spatial multiplexing,
wherein a plurality of first frames are included in the second fields,
wherein receiving addresses of the first frames each is an address of any one of the plurality of wireless communication terminals; and
a receiver configured to receive a second physical packet including a plurality of second frames multiplexed and transmitted at least in any one of frequency multiplexing or spatial multiplexing in a first time period after the first physical packet is transmitted, wherein the second frames include information indicating success or failure for reception of the first frames,
wherein
the transmitter is configured to transmit a third physical packet including a third frame in a second time period after a latest received second frame among the plurality of second frames is received, wherein the third frame includes a value indicating a length of a duration for request of suppressing an access to a wireless medium,
the second physical packet is a packet which cannot be decoded by a first wireless communication terminal whose address is different from the address of each of the plurality of wireless communication terminals, and
the third physical packet is a packet which can be decoded by the first wireless communication terminal.
