- Abstract
- Network densification with small cells deployment is regarded as one of the promising approaches to meet a huge demand of rapidly increasing wireless capacity. Such an approach can lead a dramatic increase of wireless capacity, but the interference issue still exists, which could be even more severe when the cells are too closely placed. This paper proposes an efficient spectrum sharing for a dense small cell network, where a user is usually communicable with multiple cells. Assuming either a simultaneous or a dedicated manner of the spectrum usage, an optimal spectrum sharing problem in order that the total system throughput is e maximized while user specific required data rate can be guaranteed. The proposed solution optimally determines the time portion of each spectrum usage manner, while satisfying the intended spectrum sharing goal.
