The invention relates to improve use of resource units in MU transmissions of an 802.1 1ax network. An un-associated station may receive data frames over a downlink resource unit, RU, assigned to an AID, e.g. 2045, reserved for stations not associated with the AP, The AP may use a downlink RU sharing an allocation scheme feature of an uplink RU previously used by the un-associated station. The AP may also aggregated data frames addressed to several stations within the same downlink RU, for instance to acknowledge frames previously received from the stations. The aggregated data frames may signal which respective response RUs the addressee stations should use for a next multi-user uplink transmission to respond to the AP. These approaches particularly applies to the exchange of management frames for instance to speed up the association procedure of un-associated stations.
A wireless communication method in a wireless network comprising an access point and stations, any station associating with the access point being assigned a unique association identifier used by the access point to assign, to the station, a resource unit in a transmission opportunity granted to the access point, the method comprising the following steps:
(canceled)
The method of claim 31, wherein determining the downlink resource unit is based on a number of downlink resource units assigned to the association identifier reserved for stations not associated with the access point, in the multi-user downlink transmission, and

A wireless communication method in a wireless network comprising an access point and stations, any station associating with the access point being assigned a unique association identifier used by the access point to assign, to the station, a resource unit in a transmission opportunity granted to the access point, the method comprising the following steps, at the access point:
12-14. (canceled)
The method of claim 87, wherein the allocation scheme feature includes a position of the resource unit in the corresponding plurality of resource units, according to the allocation scheme.
16-20. (canceled)
22-26. (canceled)
The method of claim 87, wherein the plurality of uplink resource units provided in the multi-user uplink transmission is triggered in the transmission opportunity by a trigger frame sent by the access point.
28-75. (canceled)
A wireless communication device forming station in a wireless network comprising an access point and stations, any station associating with the access point is assigned a unique association identifier used by the access point to assign, to the station, a resource unit in a transmission opportunity granted to the access point, the device forming station comprising at least one microprocessor configured for carrying out the steps of:
