“…Alternatively, random medium access (RMA) can be used, which usually has a much shorter duty cycle. For RMA, the transmissions from individual nodes are not jointly scheduled in time, but occur with a typically known probability, which can be exploited in order to improve the reliability of signal detection [5], [6]. Hence, a distinct advantage of the RMA is high flexibility of the system.…”

“…Note, that these optimization problems are formulated with respect to the employed linear energy harvesting model. However, due to the monotonic decrease of the harvested power with respect to ρ[m] according to (6), the solution of the respective optimization problems assuming a non-linear harvesting model would be the same as with the linear model in each symbol interval. In order to tackle these problems, we first consider the feasible performance bounds and then describe our proposed solutions.…”

Large communication networks, e.g. Internet of Things (IoT), are known to be vulnerable to co-channel interference. One possibility to address this issue is the use of orthogonal multiple access (OMA) techniques. However, due to a potentially very long duty cycle, OMA is not well suited for such schemes. Instead, random medium access (RMA) appears more promising. An RMA scheme is based on transmission of short data packets with random scheduling, which is typically unknown to the receiver. The received signal, which consists of the overlapping packets, can be used for energy harvesting and powering of a relay device. Such an energy harvesting relay may utilize the energy for further information processing and uplink transmission. In this paper, we address the design of a simultaneous information and power transfer scheme based on randomly scheduled packet transmissions and reliable symbol detection. We formulate a prediction problem with the goal to maximize the harvested power for an RMA scenario. In order to solve this problem, we propose a new prediction method, which shows a significant performance improvement compared to the straightforward baseline scheme. Furthermore, we investigate the complexity of the proposed method and its vulnerability to imperfect channel state information.

Furthermore, RMA provides a substantial flexibility for the design of large communication networks, since no scheduling is required, which simplifies the integration of new nodes into the network.…”

Ultrareliable unscheduled communication using short packets poses novel research challenges for the receiver design. Here, the uncertainty imposed by the random access and a large amount of interfering transmissions is the limiting factor for the system performance. Recently, this type of communication has been addressed in context of simultaneous wireless information and power transfer (SWIPT). The need to adapt the power splitting to the signal states according to the underlying random access has been tackled by introducing a predictor, which determines the valid states of the received signal based on the long-term observation. Hence, the power splitting factor is scaled accordingly in order to guarantee ultrareliable communication and maximized harvested energy. In this work, we extend the considered SWIPT scenario by introducing multiple antennas at the receiver side. Through this, the received energy can be substantially increased, if the energy harvesting parameters and the spatial filter coefficients are jointly optimized. Hence, we propose an optimization procedure, which aims at maximizing the harvested energy under the ultrareliability constraint. The mentioned prediction methods are combined with the optimization solution and the resulting system performance is numerically evaluated.
