%X <p>In cognitive radio, restricted by the conventional concept of spectrum sensing and power allocation, the spectrum utilization and channel rate are both small. Conventional cognitive radio framework was analyzed. A continuous sensing information based generalized framework was proposed, where after obtaining the sensing information, the secondary user won't make decision on the presence of the primary user but directly decide the power allocation parameters under the power constraints. Cases of continuous and multiple-level power allocation rules were modeled and treated separately. It is shown that the proposed framework provides the upper bound of the theoretical capacity and the conventional architectures are its special cases.</p>
