A method of improving self-coexistence of first and second centrally controlled wireless communication networks, the method comprising: listening at a first station of the first wireless communication network for a coexistence beacon; receiving at the first station of the first wireless communication network a coexistence beacon transmitted from a first station of the second wireless communication network, the coexistence beacon including information about a traffic reservation of the first station of the second wireless communication network, wherein the first station of the first wireless communication network is a remote station, and the second station of the first wireless communication network is a base station, and communicating coexistence information from the first station of the first wireless communication network to a second station of the first wireless communication network, the coexistence information being produced from the information about the traffic reservation of the first station of the second wireless communication network included in the received coexistence beacon, wherein the first and second wireless communication networks operate in proximity to each other in at least one overlapping frequency channel and with overlapping transmission times, that at least one station of the first wireless communication networks is located sufficiently close to one station of the second wireless communication network that data packets of these stations can collide or interfere with each other, characterized in that the first station of the second communication network is a remote station, wherein the first station of the first wireless communication network listens for the coexistence beacon during a time period when it is not scheduled to send or receive data in the first wireless communication network, and does not listen for the coexistence beacon during a time period when it is scheduled to send or receive data in the first wireless communication network, and wherein a coexistence beacon is transmitted from the first station in the first wireless communication network to the first station of the second wireless communication network. listening at a first station of the first wireless communication network for a coexistence beacon; receiving at the first station of the first wireless communication network a coexistence beacon transmitted from a first station of the second wireless communication network, the coexistence beacon including information about a traffic reservation of the first station of the second wireless communication network, wherein the first station of the first wireless communication network is a remote station, and the second station of the first wireless communication network is a base station, and communicating coexistence information from the first station of the first wireless communication network to a second station of the first wireless communication network, the coexistence information being produced from the information about the traffic reservation of the first station of the second wireless communication network included in the received coexistence beacon, wherein the first and second wireless communication networks operate in proximity to each other in at least one overlapping frequency channel and with overlapping transmission times, that at least one station of the first wireless communication networks is located sufficiently close to one station of the second wireless communication network that data packets of these stations can collide or interfere with each other, characterized in that the first station of the second communication network is a remote station, wherein the first station of the first wireless communication network listens for the coexistence beacon during a time period when it is not scheduled to send or receive data in the first wireless communication network, and does not listen for the coexistence beacon during a time period when it is scheduled to send or receive data in the first wireless communication network, and wherein a coexistence beacon is transmitted from the first station in the first wireless communication network to the first station of the second wireless communication network.
