“…Facing energy-constrained relay networks [1], simultaneous wireless information and power transfer (SWIPT) has been a popular research spot [2,3,4], in which the energy-hungry relay harvests energy of radio frequency signals from the transmitters and performs information forwarding by using the harvested energy and its own battery energy. Chen et al in [3] study the distributed power splitting (PS) scheme in relay interference channels.…”

Abstract. Adaptive power splitting and power allocation can provide a substantial performance gain in energy-hungry multi-antenna relay wireless networks when perfect channel state information (CSI) is available at relay. In the case when only imperfect CSI is available, the performance may significantly degrade, and robust power-splitting and power-allocation schemes are developed to save this kind of degradation. In this paper, we investigate the energy-constrained multi-antenna relay system, in which one source communicates with one destination (S-D) with the aid of an energy constrained relay. We focus on power splitting (PS) protocol to enable simultaneous energy harvesting and information forwarding, and power allocation (PA) to support both the battery power and harvested energy. The optimization problem is established under partial CSI conditions. The objective is to maximize the transmission rate of S-D pair by jointly optimizing PS and PA. Through mathematical analysis, the PS and PA are obtained.

“…One line of work is SWIPT, in which the same RF signal at the transmitter is used to deliver both information and energy to the receiver [1,13]. The other line of research focuses on designing a new type of network, termed WPCN, in which wireless terminals communicate using the energy harvested from wireless energy transfer [14][15][16][17].…”

“…Due to this, SU may experience heavy interference from PU, which deteriorates the quality-of-service (QoS) of SU. Nevertheless, since the interference is a RF signal, it can be leveraged as a potential source of energy [10], [12], [24]. For example, under time switching policy, in the energy harvesting phase of a slot, the interference can be utilized as a useful energy source.…”

Abstract-We consider a spectrum sharing scenario, where a secondary network coexists with a primary network of multiple transceivers. The secondary network consists of an energyconstrained decode-and-forward secondary relay which assists the communication between a secondary transmitter and a destination in the presence of the interference from multiple primary transmitters. The secondary relay harvests energy from the received radiofrequency signals, which include the information signal from the secondary transmitter and the primary interference. The harvested energy is then used to decode the secondary information and forward it to the secondary destination. At the relay, we adopt a time switching policy due to its simplicity that switches between the energy harvesting and information decoding over time. Specifically, we derive a closed-form expression for the secondary outage probability under the primary outage constraint and the peak power constraint at both secondary transmitter and relay. In addition, we investigate the effect of the number of primary transceivers on the optimal energy harvesting duration that minimizes the secondary outage probability. By utilizing the primary interference as a useful energy source in the energy harvesting phase, the secondary network achieves a better outage performance.
