Multichannel AP need to talk with STA only on a particular channel

[abhinav...@gmail.com]

Hello OMNETPP experts,
     I have a scenario where there is a multichannel AP and a STA. STA talks with AP through channel1 but the AP talk back with STA in channel 0 to 13. How can i restrict the AP talking with STA only in channel 1 in omnet++?

Regards,
