Abstract
Methods and apparatuses are described for wireless communications coexistence. In one aspect, a first device may detect an interference produced by a second device co-located with the first device. The first device may communicate with an access point (AP) using a free or open band and the second device may communicate with a cellular network (e.g., LTE network). In response to the detected interference, a message may be transmitted to the AP from the first device with information for the AP to determine whether to switch to a different channel in the open band to communicate with the first device. The AP may receive such a message from each terminal in at least a subset of associated terminals. The AP may determine, from the messages received, to switch to the different channel in the open band and may transmit a message to the associated terminals indicating the switch.
