1. A communication apparatus comprising:
one or more memories having instructions stored therein; and
one or more processors that, upon execution of the instructions, is configured to:
receive a signal transmitted from a base station constructing a wireless network conforming to IEEE802.11 series of standards, the signal including information on an AIFSN value, and
upon successfully transmitting data of an access category in a resource unit provided by the base station and in a case where the AIFSN value, included in the received signal, is zero for the access category, disable Enhanced Distributed Channel Access (EDCA) transmission of data of the access category that are to be addressed to the base station, whereas EDCA transmission of data of the access category that are to be addressed to another station different from the base station remains enabled,
wherein EDCA transmission of the data that are to be addressed to another station different from the base station is peer to peer traffic different from uplink traffic to the base station.
