In a heterogeneous cellular network (HetNet) consisting of tiers of densely-deployed base stations (BSs), consider that each of the BSs in the HetNet that are associated with multiple users is able to simultaneously schedule and serve two users in a downlink time slot by performing the (power-domain) non-orthogonal multiple access (NOMA) scheme. This paper aims at the preliminary study on the downlink...
Full-duplex (FD) networks promise nearly doubled spectrum efficiency for single links with beyond 100 dB self-interference cancellation capability. However, the performance of FD networking is not that straightforward, as there will be several new types of interference introduced. Hence, it is critical to exploit some radio resource management techniques to combat the annoying interference and inevitably...
Spatial modulation (SM) has emerged as a low-complexity and energy-efficient multiple-input multiple-output transmission technique, where the information bits are not only transmitted by amplitude phase modulation but also conveyed by the index of activated transmit antenna (TA). By deploying SM in downlink multi-user (DL-MU) scenarios, conventional orthogonal multiple access-based SM (OMA-SM) allocates...
Non-orthogonal multiple access (NOMA) is a major technique that is expected to lead towards the fifth generation (5G) wireless communication networks, as it involves the sharing of space resources among users in a given scenario. In this paper, we propose an uplink (UL) NOMA setup that utilizes the multiple-input multiple-output (MIMO) infrastructure. As performed in related literature, K clients...
