摘要Abstract: One fundamental issue for a CR network is how CR users establish an overlaying ad hoc link on licensed and unlicensed bands. On licensed band, the CR functions aim to detect the presence of primary users and vacate the occupied spectrum to avoid the interference. On the unlicensed band, the CR functions have to improve the efficiency and fairness of spectrum usage as well as support the QoS.
