A method and system for assigning downlink and uplink channels to a mobile station registered with a base station, which uses an interference-sensing scheme and which provides improved reliability and performance over conventional schemes. Then, in at least one embodiment, with the TFT maintaining the conducting state, a potential of a data line Sj is changed from a reference potential Vpc to a data potential Vdata to place the TFT in a conducting state. The wireless device can also include an interference determination module that 1) detects a coexistence interference profile involving the wireless device and the multiple interference-susceptible wireless devices and 2) determines a channel change for the transceiver to communicate with the network.
