RF energy harvesting can be used to power communication devices so that perpetual operation of such devices can be ensured. We consider a RF energy harvesting underlay cognitive radio system operating in slotted fashion. The primary user (PU) is equipped with a reliable power source and transmits with a constant power in all the slots. However, the secondary user (SU) harvests energy from primary's transmission and simultaneously transmits it's own data such that interference at the primary…

An iterative algorithm is developed that obtains the optimal offline power policies for primary and secondary users and investigates the effects of the secondary rate constraint and finite battery on the primary rate and the probability of cooperation.
Cooperative Spectrum Sharing With Wireless Energy Harvesting in Cognitive Radio Networks
TLDR
An algorithm is proposed to optimally allocate the bandwidth and time resources to facilitate both the EH and data transmission to maximize the area throughput of the secondary system under the performance constraint of the primary system.
Achievable Throughput of Energy Harvesting Cognitive Radio Networks
TLDR
Analysis of the theoretically achievable throughput of the secondary transmitter, which harvests energy from ambient sources or wireless power transfer systems while opportunistically accessing the spectrum licensed to the primary network, shows the temporal correlation of the primary traffic to enable efficient usage of the harvested energy.
Throughput Maximization in Wireless Powered Communication Networks
TLDR
The solution reveals an interesting "doubly near-far" phenomenon due to both the DL and UL distance-dependent signal attenuation, where a far user from the H-AP, which receives less wireless energy than a nearer user in the DL, has to transmit with more power in the UL for reliable information transmission.

The spatial throughput of the secondary network is maximized using a stochastic-geometry model where PTs and STs are modeled as independent homogeneous Poisson point processes (HPPPs) under the outage constraints for coexisting networks and obtained in a simple closed-form.
