Inter-cell interference avoidance by active coordination of scheduling for downlink on LTE like systems

摘要

In this manuscript a new simple approach to inter-cell interference mitigation for the OFDMA based cellular networks is proposed, where the prolonged scheduling period and exchange of scheduling information among neighboring eNBs is used to reduce the interference among cells. Exchange of information could be carried over an interface similar to X2 that is standardized for the LTE systems. The process is described with the optimization by weighing the received scheduling information. The advantages of the proposed scheme are demonstrated by simulation results and compared to random resource allocation and soft frequency reuse.
