Abstract

Large-scale machine communication scenarios are faced with the characteristics of a large number of terminal devices, small communication packets and frequent transmissions. Traditional multiple access technology can’t fully apply to these characteristics, so it needs to be improved and designed. In order to further improve the effect of distributed access strategy formulation of large-scale multi-source terminal for 5G, this paper proposes a distributed access technology for large-scale multi-source terminals for 5G. For distributed access scenarios, antenna units in the distributed system are scattered in the system, and each antenna unit keeps communication with the surrounding terminal equipment, which can expand the number of terminal devices randomly accessed in the same time slot. Then, taking advantage of this inherent advantage and the advantage of time-shifted pilot, this paper proposes a distributed random access scheme based on time-shifted pilot. Finally, through analysis and simulation, this paper proves that this scheme can effectively reduce the pilot collision probability of each antenna element and the average access delay in the system, which provides a technical reference for the subsequent distributed access of large-scale multi-source terminals.
