Method for performing airtime fairness control of mesh network, and associated apparatus

A method for performing airtime fairness control of a mesh network, the mesh network comprising a first wireless communications device and at least one other wireless communications device, the method comprising:

• utilizing the first wireless communications device to receive at least one first packet from a second wireless communications device among the at least one other wireless communications device, the at least one first packet carrying at least one indication related to at least one second station (STA) device connected to the at least one other wireless communications device;
• determining a first expected airtime of at least one first STA device connected to the first wireless communications device and a second expected airtime of the at least one second STA device at least according to the at least one indication and a topology of the first wireless communications device and the second wireless communications device;
• and
• adjusting the first expected airtime and the second expected airtime by controlling first medium-access operations of the at least one first STA device and second medium-access operations of the at least one second STA device in a time-division manner, for equalizing respective airtime of all currently connected STA devices of the mesh network.
