1. A virtual stream (VS) in a basic service set (BSS) in a wireless local area network, the virtual stream comprising:

  • a unidirectional path in the wireless local area network between a station sourcing a quality of service (QoS) session and at least one station receiving the QoS session in the same BSS;

    wherein the VS is set up by a QoS management entity (QME) within a point coordinator (PC) station of the BSS to transport, under at least one predetermined QoS constraint, a traffic of the QoS session from a local logical link control (LLC) entity to at least one peer LLC entity in the same BSS; and

    wherein the PC station announces multiple transmission opportunities in a single frame; and

    wherein the VS is torn down by the QME of the PC-station upon termination of the QoS session.
