A practical tessellation-based load-balancing scheme in Heterogeneous Cellular Networks using MIMO
نویسندگان
چکیده
In this paper, in order to optimize the cell range expansion (CRE) and enhanced intercell interference coordination (eICIC) in long-term evolution advanced (LTE-A) heterogeneous cellular networks (HCNs) using multiple-input multiple-output (MIMO), a practical tessellation-based load balancing scheme is proposed, which requires little change in existing protocols. It is shown that the tessellation obtained by the proposed scheme is quite consistent to the optimal tessellation for various MIMO scenarios so that the proposed scheme can provide much better load balancing performance compared to the conventional common bias scheme. Keywords—LTE-A Systems; Load balancing; cell-specific bias

In 3G cellular networks, high data-rates can be achieved. However, fundamental capacity limitation still exists. Call requests are frequently blocked in hotspot areas. Load balancing among cells helps to solve this problem and to utilize the radio resources. However, existing load balancing schemes are not designed specifically for 3G networks. Some schemes are not flexible enough or even pract...
