Query on queues in mesh mode

Hi All

I am trying to understand the queuing mechanism wireless mesh networks.

As per AP mode is concerned, there are four queues (BK, BE, Vi, VO)
and traffic is controlled based on CWmin, CWmax, AIFS and TxOP.

Does, mesh mode also involve these queues? Does mesh mode have any
queue or it is just a single queue?

Could someone clarify this?

Best Regards
