Abstract: The invention relates to a base station constructing a wireless network conforming to IEEE802.11 series of standards, comprising:
sending means for sending a signal, the signal including information on an AIFSN value,
wherein a first station having received the signal sent by the sending means is controlled so that, in a case where the AIFSN value indicated by the information in the signal is zero, Enhanced Distributed Channel Access (EDCA) transmission of data of an access category that are to be addressed to the base station is disabled whereas EDCA transmission of data of the same access category that are to be addressed to a second station different from the first station remains enabled,
wherein the access category is the same as an access category for data that the first station has successfully transmitted via a resource unit conforming to the IEEE802.11 series of standards.

Abstract: In an 802.11ax network with an access point, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access point. The access point indicates, through the trigger frame, whether the nodes have to sense an energy of the medium below a threshold before transmitting data on one or more resource units.
