“…Also, in outer code part 1, the degree of outer connections up to 3 is allowed. In outer code part 2, the degree of information VN (except the information VN used for precoding) is set to either 3 or 4 because at least 3 repetitions of each information VN is required to guarantee the LMDG property [5] and it has been reported that repetitions more than four may degrade the iterative decoding threshold [3, 4]. Also, in outer code part 2, the

“…the punctured VN) should include at least one single edge to operate the message‐passing decoder well [6] and the sum of the entries of the corresponding column, except the first one (i.e. precoder) should be >3 in order to achieve a good error floor performance [5]. Note that the above constraints reduce the search space significantly compared with the full search space while avoiding meaningful performance degradation.…”

“…The PC matrix (PCM) is obtained by two‐step lifting as in [5], in which the first lifting uses a small expansion

B_{1} = 3

and the second lifting uses the circulants of the identity matrix with size

“…The encoding of an RC‐ARACA code is as follows. (i) An HRC is encoded in four steps [5] with a linear encoding complexity. (ii) Each IRC is encoded with either only block SPC (BSPC) operations for degree‐1 parity VNs or a BSPC operation and the combination of the bit interleaver, accumulator and deinterleaver for degree‐2 parity VNs.…”

“…(i) Samsung codes [2] suffer from error floors due to their lack of the linear minimum distance growth (LMDG) property. (ii) PBRL‐1 [3] and PBRL‐2 [4] codes suffer from the lack of an efficient encoder structure and require employing a dense block‐circulant systematic generator matrix (BCSGM) with a high complexity for encoding an HRC [5]. Recently in [5], Jeon and Kim proposed accumulate repeat accumulate check accumulate (ARACA) codes, which can simultaneously provide the above three criteria.…”

A design method for rate-compatible (RC) accumulate repeat accumulate check accumulate (ARACA) codes as protograph-based RC low-density parity-check codes is presented. The proposed RC-ARACA codes provide not only good iterative decoding thresholds with the linear minimum distance growth property but also efficient encoder/decoder structures with low complexities, so that they are appropriate to ultrareliable and low latency communication services for fifth generation.

This paper presents novel Ultrareliable and lowlatency communication (URLLC) techniques for URLLC services, such as Tactile Internet services. Among typical use-cases of URLLC services are tele-operation, immersive virtual reality, cooperative automated driving, and so on. In such URLLC services, new kinds of traffic such as haptic information including kinesthetic information and tactile information need to be delivered in addition to high-quality video and audio traffic in traditional multimedia services. Further, such a variety of traffic has various characteristics in terms of packet sizes and data rates with a variety of requirements of latency and reliability. Furthermore, some traffic may occur in a sporadic manner but require reliable delivery of packets of medium to large sizes within a low latency, which is not supported by current state-of-the-art wireless communication systems and is very challenging for future wireless communication systems. Thus, to meet such a variety of tight traffic requirements in a wireless communication system, novel technologies from the physical layer to the network layer need to be devised. In this paper, some novel physical layer technologies such as waveform multiplexing, multiple access scheme, channel code design, synchronization, and full-duplex transmission for spectrally-efficient URLLC are introduced. In addition, a novel performance evaluation approach, which combines a ray-tracing tool and system-level simulation, is suggested for evaluating the performance of the proposed schemes. Simulation results show the feasibility of the proposed schemes providing realistic URLLC services in realistic geographical environments, which encourages further efforts to substantiate the proposed work 1 .
