METHOD AND APPARATUS FOR SENSING PRESENCE OF AN INCUMBENT SIGNAL ON A SECONDARY RADIO CHANNEL
摘要
<p>A remote station (202) communicates with a base station (204) over a secondary radio channel (206). During communication, the remote station determines channel conditions of the secondary radio channel. Based on the channel conditions, the remote station selects one or more sensing methods to be performed on the secondary radio channel. The result of performing the sensing method is used to determining whether an incumbent signal is present on the secondary radio channel.</p>
