Joint Sub-Channel Assignment and Power Allocation in Heterogeneous Networks: An Efficient Optimization Method

This letter is concerned with joint sub-channel and power allocation in a heterogeneous network. We consider the uplink of a co-channel framework where a macrocell shares the orthogonal frequency division multiple access (OFDMA) sub-channels with a number of small cells (SCs). We maximize the weight...
