Feasibility of UMTS-TDD mode in the 2500- 2690MHz Band for MBMS

Spectrum Arrangement Scenarios for 25002690MHz band allocation according to ITU-R include 7 different cases, however it remains to be known whether a single scenario or several should coexist in the future. For the 7 scenarios it’s necessary to get to know which are the most interesting and which will be more useful to broadcasting/multicasting using UTRA TDD (Time Division Duplex) or FDD (Frequency Division Duplex). In the 2500-2690 MHz band, we investigate the feasibility of future Enhanced-UMTS TDD mode to carry digital broadcast services such as MBMS (Multimedia Broadcast Multicast Service) and provide to a number of existing operators in the actual band, an asymmetric capacity extension, with no impact on existing frequency arrangements. The objective of this work is to choose and study the suitable scenario(s) to provide multimedia broadcast multicast services based on the UTRA TDD mode.
