Towards 5G wireless cellular networks: Views on emerging concepts and technologies

The communications theory is a well established field whose origin could be traced back to approximately the early 20th century. This rich theory has found a very successful application since the 1980´s - the mobile telephony through wireless cellular networks. Since the standardization process for the 4G technologies (LTE, LTE-Advanced) is in its final stage, it is time for the research community to articulate on what is likely to come next.
