“…For the FDS‐FDR style, however, the relay node is allowed to receive signals from the two sources and then broadcast them to the sources over the same time and frequency channels, simultaneously. The authors of [3–12] investigated the SE and outage performance of the HDS‐FDR and FDS‐FDR styles, and found that the bigger RSI will lead to worse SE and higher outage probability, and the corresponding SIC techniques were studied in [13–16].…”

“…By simultaneously exploiting path loss savings known from relaying scenarios and the diversity inherent to any scheme involving spatially separated transmitters, proving that CRS can make full use of the advantages of relay [13,14]. Later in [15], a CRS scheme based on AF and decode-and-forward (DF) relay is investigated to improve the throughput of the system. Results from the aforementioned studies generally show that CRS has broad prospects of application in communication systems.…”

This paper presents a time slot‐split non‐orthogonal multiple access (TSS‐NOMA) scheme for full‐duplex (FD) cooperative communication systems to improve resource utilisation. Aiming at the problem of low bandwidth efficiency when pairing users, TSS‐NOMA divides a complete time slot into several parts to improve the pairing process. Users can occupy all bandwidths in different slots to reduce the waste of bandwidth resources. Unlike the scheme of forwarding a single signal, TSS‐NOMA decodes the information symbols of relay, and re‐encodes the messages through the new power allocation factors of successfully paired users. The hybrid symbols are sent to increase the proportion of central users' own signals received by themselves, thus improving the ergodic capacity of the system. To maximise the minimum achievable rate of the system, TSS‐NOMA optimises the power allocation at the base station, and the relay. The performance of TSS‐NOMA is verified by simulation, where numerical results show that this scheme can achieve higher spectral, and energy efficiency.

For years, relay communications have been witnessed to extend the network coverage and improve the throughput and reliability of wireless systems. In this paper, we focus on throughput maximization for the two-way buffer-aided relay network with finite data buffers and limited energy battery, wherein relays have no fixed power supply and they replenish energy from the Radio Frequency (RF) signal radiated by source nodes. Specifically, by jointing the time switching and energy splitting for RF energy harvesting, we introduce a three time-subslot transmission model to balance the energy storage and the energy consumption for communication. On top of this transmission model, we formulate an optimization problem for throughput maximization of relay network. We purposely convert the non-convex optimization problem into a convex one by carefully decoupling and relaxing. Further, we theoretically derive the maximum throughput and apply an iterative algorithm to achieve the suboptimal solution based on relay selection and power allocation. In addition to solving the no-delay limited throughput maximization problem, we put forward the solution of the delay limited transmission in the two-way buffer-aided multi-relay networks. Extensive simulations have been conducted to demonstrate that our proposed strategy is able to significantly improve the sum-throughput under transmission energy and delay constraints.
