Data applications can tolerate an initial delay before packet transmission begins. It is possible to take advantage of this initial delay to reduce the energy required to operate the small access points (SAPs) and decrease transmission power in small cell networks. To demonstrate the trade-off between delay and transmit power, we consider a simple access scheme and analyze the distribution of the...
Range expansion and inter-cell interference coordination (ICIC) can improve the capacity and fairness of heterogeneous network (HetNet) deployments by off-loading macrocell users to low-power nodes. Due to difficulties in analytical treatment, current studies for range expansion and ICIC in HetNets rely mostly on simulations. In this letter, first, off-loading benefits of range expansion in HetNets...
