With the development of 5G technology, the power allocation problem in non-orthogonal
multiple access technique (NOMA) becomes one of the key technologies. Due to the high …

This paper studies the imperfect channel state information (CSI) based joint resource
scheduling problem for deadline constrained transmission. We present a holistic system …

In the massive Multiple-Input Multiple-Output (MIMO) system, a large number of transmit
