Cooperative Spectrum Sharing of Cellular LTE-Advanced and Broadcast DVB-T2 Systems

Abstract

The allocation of parts of the Ultra High Frequency (UHF) band to International Mobile Telecommunications (IMT) technologies on a co-primary basis with terrestrial broadcasting technologies has been the major change in worldwide spectrum allocation in recent years. Nowadays, thanks to the Second Generation for Terrestrial Digital Video Broadcasting (DVB-T2) and the Long Term Evolution Advanced (LTE-A) technologies a new model of cooperation between cellular and broadcasting systems arises, where the cellular network can use of broadcast spectrum using time multiplexing. This paper proposes the cooperative spectrum sharing of DTT spectrum between DVB-T2 systems and LTE-A cellular networks by means of the use of DVB-T2 FEF for LTE-A analyzing the potential benefit.
