RESOURCE UNITS FOR UNASSOCIATED STATIONS AND GROUPED MULTI-USER TRANSMISSIONS IN 802.11AX NETWORKS

摘要

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.
