Abstract
In a 802.11 be multi-AP collaboration, collaborated devices obtaining shared resources announced by a collaborator AP re-announce the shared resource for the stations out of the transmission range of the collaborator AP. Given the short time available, the re-announcing frame binary repeats most of the initial announcement by the collaborator AP, in particular substantially the whole MAC payload thereof. In order to facilitate the identification of the re-announcing, the latter comprises an empty TA field or no TA field in its header. This additionally allows any AP to act as the coordinator AP.
