| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To realize the fifth generation (5G) mobile communication systems, we proposed cooperative distributed antenna transmission (CDAT). In the mobile communication systems, many active user are existed in macro-cell, and the received power and the CCI power of each user is varied according to user’s position. Therefore, the user scheduling scheme (Proportional Fair (PF), Round-robin (RR), Max-SNR) is required for effectively utilizing a radio communication band while ensuring the fairness of each user. We have been studying user scheduling scheme for CDAT using space-time block coded (STBC) diversity that can obtain large spatial diversity order while using arbitrary distributed antennas. We have found in our previous work that as the frequency selectivity of the channel gets stronger, the differences in averaged channel gains, due to multipath fading, among active users is substantially reduced and therefore even the RR scheduling provides the link capacity similar to the PF scheduling. To improve the link capacity, increasing number of distributed antennas in macro-cell is effective. However, small-cell network using more than 7 distributed antennas has not been sufficiently examined. In this paper, we report the result of studies on large-scale distributed antenna small-cell network using seven or more distributed antennas. We evaluate, by computer simulation, the relationship of average sum link capacity, user link capacity, and Jain’s fairness index. We discuss the impact of number of distributed antennas and the impact of distributed antenna deployment (uniform and random). |
