demands. Basically, this paper provides a comprehensive review
of the applications and challenges associated with different generation of communication system and technological enhancement
towards their fulfilment. In addition, we discuss main features
of next generation cloud radio area network architecture along
with the cooperative transmission schemes. Further, it is shown
that Cloud Radio Access Network (CRAN) i
