We jointly investigate resource allocation along with dynamic activation of energy harvesting base stations in a two-tier heterogeneous network (HetNet) under energy harvesting as well as interference constraints. Considering the varying channel condition, user activity, and arrival of harvested energy in different time slots, we determine resource allocation and dynamic activation of energy harvesting...
We study the downlink resource allocation problem for simultaneous wireless information and power transfer (SWIPT) in small cells underlaying a macrocell in a two-tier heterogeneous network. For SWIPT, we consider both time-switching and power-splitting approaches. We determine downlink transmit power of small cell base stations along with time-switching/power-splitting variables for SWIPT to jointly...
Wireless information and energy transfer in multitier cellular networks is a new research paradigm in wireless communications. While interference mitigation is one of the major challenges in conventional multi-tier networks, wireless energy harvesting capability considers interference signal as a source of energy. In this paper, we consider simultaneous wireless information and energy transfer in...
