The novel technique of using the indices of the active subcarriers of orthogonal frequency division multiplexing (OFDM) to transmit data, called index modulation-aided OFDM or OFDM-IM is a recently proposed multicarrier transmission technique for achieving high spectral and energy efficiency in the forthcoming fifth generation (5G) networks. In this paper, the principle of operation of OFDM-IM, its dual mode counterpart DM-OFDM and the OFDM with multiple constellation (OFDM-MC) schemes were firstly investigated. We review a number of the recent promising advances in these technologies. Their implementations in various applications such as visible light communication (VLC) and Asynchronous mMTC Networks etc are then introduced. Finally, their various performances are compared with each other to authenticate their ability for enhancing the energy efficiency of various physical (PHY) layer technologies. We see that, at the BER of 10^{-5}, the SNR of precoded OFDM-MC is 33 dB while that of precoded DM-OFDM is 37 dB and that of precoded OFDM-IM is 38 dB, a clear 4 dB to 5 dB advantage. This advantage is due to precoded OFDM-MC diversity order of 4 compared to the two other schemes with diversity order of 2.
