Previous works established the capacity region for some special cases of\ndiscrete memoryless degraded cognitive interference channel (CIC) with\nunidirectional destination cooperation (UDC). In this letter, we characterize\nthe capacity region of the general discrete memoryless degraded CIC-UDC. The\nobtained results imply that the capacity region is achieved by the\nGel'fand-Pinsker coding at the cognitive transmitter, superposition coding at\nthe primary transmitter and decode-and-forward at the relay. Furthermore, using\nthis general result and a novel converse analysis, we establish the capacity of\nthe Gaussian degraded CIC-UDC, which had been open until this work.\n
