MIMO processing plays a central part towards the recent increase in spectraland energy efficiencies of wireless networks. MIMO has grown beyond theoriginal point-to-point channel and nowadays refers to a diverse range ofcentralized and distributed deployments. The fundamental bottleneck towardsenormous spectral and energy efficiency benefits in multiuser MIMO networkslies in a huge demand for accurate channel state information at the transmitter(CSIT). This has become increasingly difficult to satisfy due to the increasingnumber of antennas and access points in next generation wireless networksrelying on dense heterogeneous networks and transmitters equipped with a largenumber of antennas. CSIT inaccuracy results in a multi-user interferenceproblem that is the primary bottleneck of MIMO wireless networks. Lookingbackward, the problem has been to strive to apply techniques designed forperfect CSIT to scenarios with imperfect CSIT. In this paper, we depart fromthis conventional approach and introduce the readers to a promising strategybased on rate-splitting. Rate-splitting relies on the transmission of commonand private messages and is shown to provide significant benefits in terms ofspectral and energy efficiencies, reliability and CSI feedback overheadreduction over conventional strategies used in LTE-A and exclusively relying onprivate message transmissions. Open problems, impact on standard specificationsand operational challenges are also discussed.

This paper slightly improves the upper bound in Thangaraj et al. for thecapacity of the amplitude-constrained scalar AWGN channel. This improvementmakes the upper bound within 0.002 bits of the capacity for$\frac{E_b}{N_0}\leq 2.5$ dB.

Lee H, Lee K-J, Kim H, Clerckx B, Lee Iet al., 2016, Resource Allocation Techniques for Wireless Powered Communication Networks With Energy Storage Constraint, IEEE Transactions on Wireless Communications, Vol: 15, Pages: 2619-2628, ISSN: 1558-2248

This paper studies multiuser wireless powered communication networks, where energy constrained users charge their energy storages by scavenging energy of the radio frequency signals radiated from a hybrid access point (H-AP). The energy is then utilized for the users' uplink information transmission to the H-AP in time division multiple access mode. In this system, we aim to maximize the uplink sum rate performance by jointly optimizing energy and time resource allocation for multiple users in both infinite capacity and finite capacity energy storage cases. First, when the users are equipped with the infinite capacity energy storages, we derive the optimal downlink energy transmission policy at the H-AP. Based on this result, analytical resource allocation solutions are obtained. Next, we propose the optimal energy and time allocation algorithm for the case where each user has finite capacity energy storage. Simulation results confirm that the proposed algorithms offer about 30% average sum rate performance gain over conventional schemes.
