—Cellular users in indoor environments have difficulty to enjoy high rate services supplied only by macro base station (MBS) due to the penetration loss. Smallcell, as a complement to Macrocell, provide the enhanced coverage through constituting heterogeneous network (HetNet) with MSBs. HetNet is an effective candidate for green communications. However, the interference in HetNet is still a challenging issue. In this paper, we propose an energy-efficient subchannel and power allocation scheme…

This paper proves that a special form of power allocation, in which only one transmitter transmits a signal for each subchannel, performs better than power allocation by conventional schemes, and proposes an efficient scheme for jointly allocating power and a subchannel based on the binary power allocation.
