Tier-Aware Resource Allocation in OFDMA Macrocell-Small Cell Networks
Tier-Aware Resource Allocation in OFDMA Macrocell-Small Cell Networks
We present a joint sub-channel and power allocation framework for downlink transmission an orthogonal frequency-division multiple access (OFDMA)-based cellular network composed of a macrocell overlaid by small cells. In this framework, the resource allocation (RA) problems for both the macrocell and small cells are formulated as optimization problems. Numerical results …
