Co-primary spectrum sharing for denser networks in local area

This work investigates co-primary spectrum sharing problem in the local area indoor dense deployment scenario. A spectrum sharing method and relevant mechanism are designed to achieve flexible spectrum usage amongst multiple operator networks. This proposed solution improves spectrum efficiency by making small cells more flexibly and efficiently utilize whole spectrum resources via intra operator spectrum allocation and inter-operator spectrum coordination. Intensive system level simulations give a detailed verification of the performance of this spectrum sharing approach.
