Abstract
The present invention provides methods for noise reduction and bandwidth expansion in wireless communication and the devices thereof. The method in accordance with the present invention may include identifying a plurality of neighbor nodes with respect to a central node; sending a first communication signal to the plurality of neighbor nodes, wherein the first communication signal is only sent to the nodes that are considered as the plurality of neighbor nodes by the central nodes; and based on the first communication signal, when the central node is transmitting data to one of the plurality of neighbor nodes, the other nodes of the plurality of neighbor nodes do not send data in the same channel, thereby reducing the noise in the wireless network.
