| Abstract(in English) | Toward 5th generation mobile communications system, various researches for small cells with massive MIMO, which are effective for off-loading the heavy mobile traffic around crowded places to networks from macro cell systems, have been studied. Because the small cell base stations (SBSs) with high-SHF bands will be allocated on walls of buildings, it is expected that the wireless entrance systems for the SBSs can accelerate its prompt service development due to its installation flexibility. In 5G, both very low latency and BER performance are required as well as high speed communication ability. In case of installation of SBS to a signboard on a wall, the size of the SBS itself and its antenna system should be as small as possible. The situation is different from the cases with large parabolic antenna, therefore the effects of reflected waves in the street canyon will not be negligible small and it usually degrades its BER performance and cause high level error floor on high speed wireless communication over 10 Gbit/s. In order to overcome the problem, introducing automatic repeat request (ARQ) schemes is reasonable approach, however, the ARQ improves BER performance at the sacrifice of transmission delay performance. Because of strict delay requirement for 5G, the target delay time for the wireless entrance systems is expected to be quite low around 100-150?s. In this paper, we propose a new ARQ scheme with very low latency and report its basic characteristics with computer simulations and analytic approach. |
