We study resource allocation for energy-efficient communication in multi-cell orthogonal
frequency division multiple access (OFDMA) downlink networks with cooperative base …

In this paper, new strategies are devised for joint load balancing and interference
management in the downlink of a heterogeneous network, where small cells are densely …

In the area of energy-efficient (EE) resource allocation, only limited work has been done on
consideration of both transmitter and receiver energy consumption. In this paper, we …

In this paper, we investigate energy-efficient downlink resource allocation in heterogeneous
orthogonal frequency division multiple access (OFDMA) networks, and formulate the energy …

Orthogonal frequency-division multiplexing (OFDM), with its own advantages of spectral
