Figure 3From: Beamforming techniques for enabling spatial-reuse in MCCA 802.11s networksExample of an MCCA opportunity (MCCAOP ) reservation handshake. The STA A is the MCCAOP owner and sends a MCCAOP Setup Request to the STA B. The proposed time slot does not interfere with other MCCAOPs and the STA B replies with a MCCAOP Setup Reply control frame to accept the request. The node C, a neighbor of the STA B, overhears the reply frame and acquires the timing information of the reserved time slot. The STA C updates its NAV and will hence refrain from transmitting on this time slot.Back to article page
