TL;DR: This paper designs a space-time cooperative system based on orthogonal frequency division multiplexing (OFDM), which is referred to as a cooperative (CO)-OFDM system, and devise a frame structure, on which to build practical timing and frequency synchronization algorithms and a channel estimation algorithm.

TL;DR: The network infrastructure of the LTE-Advanced is presented, and an in-depth overview of enabling technologies from the physical layer aspects, including carrier aggregation, advanced multiple-input multiple-output (MIMO) techniques, wireless relays, enhanced inter-cell interference coordination (eICIC), and coordinated multipoint (CoMP) transmission/reception are presented.

TL;DR: The aim is to maximize the sum rate and energy efficiency under ULU achievable information throughput constraints by jointly optimizing beamforming and time allocation and to improve the objectives with convergence guaranteed.

TL;DR: This paper aims to design linear precoders/beamformers for signal superposition at the base stations of NOMA multiple-input multiple-output multi-cellular systems to maximize the overall sum throughput subject to the users’ QoS requirements, which are imposed independently on the users' channel conditions.

TL;DR: An antenna-assisted round robin scheduling (AA-RRS) scheme to improve the conventional RRS scheme is proposed and it increases the system capacity through the effective use of multiple antennas in achieving a diversity effect from multiple users.
