摘要
In accordance with a method for communicating over a channel in a frequency band (e.g., an unlicensed frequency band) shared by different radio access technologies, prior to transmitting a signal beginning at a predetermined time on a first channel in a frequency band in accordance with a first radio access technology (RAT), the first channel is sensed to determine if it is unoccupied during a specified first duration of time for a specified second duration of time. If the first channel is unoccupied for the specified second duration of time, a channel reservation signal is immediately transmitted on the first channel. The channel reservation signal is decodable by a node operating in accordance with a second RAT different from the first RAT.
