The paper investigates the possibility of reusing frequencies of a terrestrial digital video broadcasting (DVB-T) network for a UMTS Terrestrial Radio Access Network (UTRAN) with negligible influence on the DVB-T performance. A frequency division duplex (FDD) UTRAN is deployed such that it can reuse all frequencies of the DVB-T network in each DVB-T frequency reuse cluster in the downlink, with a predefined level of (negligible) interference from the UTRAN to DVBT. The downlinks of both networks can thus coexist in the same frequency spectrum, thereby increasing the spectral efficiency. The uplink of UTRAN-FDD is assumed to operate in traditional non-coexistence and is therefore not considered. Close to 100% of the capacity of a non-coexisting UTRAN are achievable for typical UTRAN cell sizes, with only marginal increase of outage in the DVB-T network.
