Abstract :
Recently, the duality between capacity regions of certain single and multiple antenna MAC with SIC and BC with DPC was proved under the assumption of perfect CSI at the transmitter as well as the receiver. Considered is the case in which the transmitter has only statistical CSI. It is shown that the average rate region of the SISO BC is a subset of the average rate region of the SISO MAC and that there is a lack of duality between the MAC and BC
