“…Numerical outcomes show that this scheme improves the system performance according to the introduced utility function. In some scenarios, e.g., the uniform scenario, we found that reassociation may not provide advantages compared to FFR alone: this is in line with findings in [14], indicating that FFR and load balancing are to some extent complementary, because FFR is a powerful load balancing technique in itself.…”

Maximizing system throughput and bandwidth utilization while guaranteeing fairness among users is a core technical challenge in the design of next generation cellular networks. In this context, fractional frequency reuse (FFR) is a helpful tool if it is flexible in terms of resource and power allocation as well as scheduling. Complementary to this tool, a well-chosen association of users to base station sectors can yet be another important factor, particularly when users are distributed unevenly in space.Here we propose a load balancing scheme that combines flexible FFR with an unrestricted association of users to sectors or base stations, thereby effectively increasing the user data rates in the dense regions of the network. In a first step, we perform virtual joint power allocation and scheduling so as to determine the best sectors for maximizing the throughput for a given user. In a second step, users are actually associated to the best sectors, which are not necessarily the ones providing the strongest signal. Simulation results show that our proposed mechanism provides fairness by load balancing while still maintaining the throughput over all users.

“…As defined in [10], the gain of the ENB antenna is composed from a horizontal and a vertical antenna pattern and is described by formulas (2,3,4). Assuming a straight line between the ENB and UE position, φ describes its deviation to the antenna's maximum gain direction and θ describes its angle relative to the horizontal ground plane for a height of 30.5m.…”

“…Various mechanisms can be employed for LB: the modification of transmit power and antenna downtilt angles can be used to physically shift the border between neighboring ENB, coordination of interference between neighbors increases the channel capacity and the coordinated adaptation of the cell individual offset (CIO) between ENBs can be used to virtually shift the cell border. A performance evaluation and further details on these methods can be found in [3].…”
