“…The performance analysis reported in all of the abovementioned treatises on FBL communications have either considered a conventionally powered relay-aided OMA-based single user DL communication system [29]- [33] or an energy harvesting-enabled relay-aided single user OMA-based dualhop DL communication scenario [51]- [53]. Alternatively, simple point-to-point communication scenarios were considered, where either an energy harvesting-enabled source communicates with a single destination over FBL [46], [47], [50] or a conventionally powered source employs wireless energy transfer (WET) to enable information decoding at the receiver before information transmission [49].…”

A finite blocklength (FBL) twin-user non-orthogonal cooperative downlink system is considered, wherein a base station simultaneously communicates with the users whilst relying on simultaneous wireless information and power transfer (SWIPT) enabled energy harvesting relay. Closed-form analytical expressions are obtained for the end-to-end average block error rate (BLER) assuming potentially dissimilar Nakagami-m fading links. Furthermore, asymptotic expressions are derived for the individual user's end-to-end average BLER performance and diversity order at high signal to noise ratios (SNRs). Additionally, since, the stronger user's signal is detected, while assuming the weaker user's signal to be interference, an analytical bound has been obtained for characterizing the effect of this interference on the BLER performance of both users. Furthermore, a framework is developed for joint relay splitting factor and user power allocation towards end-to-end blocklength minimization under strict reliability constraints by converting the original non-convex optimization problem to a convex geometric program (GP) that can be solved efficiently. Simulation results are presented to validate the analytical expressions derived and illustrate the efficacy of the proposed scheme. Index Terms-Non-orthogonal multiple access (NOMA), finite blocklength (FBL) communication, dissimilar Nakagami-m fading links, energy harvesting, simultaneous wireless information and power transfer (SWIPT), product of Gamma random variables, geometric program (GP).

“…Moreover, effectiveness of collaborative core algorithms are fundamental research highlights-how to construct advantage topology network structure and obtain more efficient transmission quality. At present, cooperative selection algorithms mainly include single node selection and multiple nodes selection, the former contains best node selection, N-th [9,10], the latter contains several classical and available nodes subsets selection. Generally speaking, algorithms based on subsets selection are relatively more effective than algorithms based on single selection [9][10][11][12][13][14][15].…”

<p>Although Cooperative Communications (CC) already exists in 4G LTE/5G, performance improvement is just not enough, hence, how to apply collaborative technology in 6G to achieve Internet of Everything and improve communication quality significantly is one of most important issues. As 5G communications standard has gradually established recently, CC has been one of most critical communication technologies which plays a founding role on Internet of Everything in 6G networks. Thus, in this study we propose new 6G enabled ultra-massive Machine Type Communication (mMTC) framework based on space-ground integrated networks, and consider that collaborative ideology has been regarded as foundation theory which widely exists in future multiple hybrid scenarios, such as, Cognitive-Internet of Things (C-IoT) networks, UAVs (Unmanned Aerial Vehicles) communications, air-space-ground integrated networks, underwater acoustic communication and so on. Besides, we discuss other key communication technologies that are closely combined with unique communication scenes, and elaborate critical problems that shall be solved in 6G ultra-mMTC Internet of Everything networks. Furthermore, we discuss extreme low-complexity and fast ultra-massive relays selection algorithm to apply in all sorts of future 6G scenarios. At last, it is concluded that for arbitrary two communication points (source/destination devices, sensors, relays, IoT nodes and so on), ideology of nodes selection of collaborative communication is theory of foundation to realize and optimize communication transmission in 6G Internet of Everything ultra-mMTC networks. </p>

“…In [11], a multi-terminal URLLC network was considered and the network reliability with multihop cooperative diversity was investigated in the FBL regime. A multi-relay system with the best relay selection approach was proposed in [12] for the FBL regime, and the achievable throughput bound was calculated using the polar codes. In [13], the author considered the cooperative relaying scenario with perfect CSI for a quasi-static Rayleigh fading channel and derived the outage probability of two-hop DF, SC, and MRC protocols.…”

In this paper, the performance of a cooperative relaying technique in a non-orthogonal multiple access (NOMA) system is considered in short packet communications with finite blocklength (FBL) codes. We examine the performance of a decode-and-forward (DF) relaying along with selection combining (SC) strategy at the receiver. Our goal is optimal power and blocklength allocation to attain maximum users' fair throughput in a downlink NOMA (DL-NOMA) system with two users, where the user with a stronger channel (strong user) acts as a relay for the user with a weaker channel (weak user). For this purpose, an optimization problem is formulated and an analytical solution is proposed. Numerical results show that the proposed Cooperative NOMA scheme improves the users' fair throughput in comparison with the NOMA in the FBL regime.Index Terms-finite blocklength, short packet communication, URLLC, cooperative NOMA, max-min fairness.
