Duplex method TDD Number of TDMA multiplexing 4 Number of multiplexing Depends on channel bandwidth Operation channel bandwidth 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, 20 MHz Subcarrier frequency spacing 37.5 kHz Number of FFT points (channel 32 (1.25), 64 (2.5), 128 (5), 256 (10), 512 (20) bandwidth: MHz) Frame duration 5 ms Number of slots 8 slots (4 downlink/4 uplink: symmetry) Modulation method BPSK, QPSK, 16-QAM, 64-QAM, 256QAM Channel assign Autonomous decentralized control Basic cell size Micro-cell Connection technique Sub-channel connection, slot connection Technologies of efficient spectral utilization Adaptive antenna, SDMA, MIMO Peak channel transmission rate/5 MHz Uplink: 9.85 Mbit/s (in case of SISO, symmetry) Downlink: 10.7 Mbit/s The MAC layer of Global Platform” has a very simple structure when seeing with the “eXtended frequency axis and the time axis. This is because it is valued to keep continuously using the same frequency used between the base stations and terminals. As a result, a certain base station can monitor the frequency and timing used in the surroundings, and it is also able to choose to use the frequency and timing of best conditions. In addition, Global Platform” has its uplink and “eXtended downlink speed symmetric on the axis of time, which enables constant speed also for the uplink. By this, it enables real-time movie uploading and mobile video conference without inconvenience.
