Analysis of Carrier Utilization in Full-Duplex Cellular Networks by Dividing the Co-Channel Interference Region

We focus on the intra-cell co-channel interference between users in a full-duplex (FD) cellular network where FD enabled base stations are deployed with traditional half-duplex (HD) mobile stations. In order to suppress the co-channel interference, a cell partitioning method is proposed to divide th...

Description
Summary:We focus on the intra-cell co-channel interference between users in a full-duplex (FD) cellular network where FD enabled base stations are deployed with traditional half-duplex (HD) mobile stations. In order to suppress the co-channel interference, a cell partitioning method is proposed to divide the whole interference region into several partitions and allocate the frequency resources to them properly. The carrier utilization of such orthogonal frequency division multiple access (OFDMA)-based cellular networks is also analyzed theoretically to verify the proposed partitioning scheme. Our results show that the achievable gain in spectral efficiency over traditional HD systems increases with the number of users and decreases with the number of the partitions.
