Use of the 2500-2690 MHz Band for Multimedia Broadcast Multicast Service

The viable deployment of both UMTS Terrestrial radio access network (UTRAN) modes, Frequency Division Duplex (FDD) and Time Division Duplex (TDD) in additional and diverse spectrum arrangement will be investigated. Simulations are performed to study the interference between UTRATDD and the UTRA-FDD having adjacent channel carriers. This expansion spectrum will be predominantly used for expanding capacity, by means of macro, micro and pico cells in “hotspot” areas. In some scenarios, the TDD and FDD cells can use the same frequency, which will increase the capacity and utilize the underused UTRA-FDD UL resources. This study is one of the tasks of the B-BONE project (Broadcasting and multicasting over enhanced UMTS mobile broadband networks). In the 2500-2690 MHz band, we investigate the feasibility of future Enhanced UMTS FDD and TDD modes with multi-carrier and MIMO to carry digital broadcast services such as Multimedia Broadcast Multicast Service (MBMS).
