Analytical Model and Feedback Predictor Optimization for Combined Early-HARQ and HARQ [PDF]
Mathematics, 2021 In order to fulfill the stringent Ultra-Reliable Low Latency Communication (URLLC) requirements towards Fifth Generation (5G) mobile networks, early-Hybrid Automatic Repeat reQuest (e-HARQ) schemes have been introduced, aimed at providing faster feedback

Adaptive Cross-Packet HARQ [PDF]
IEEE Transactions on Communications, 2017 In this work, we investigate a coding strategy devised to increase the throughput in hybrid ARQ (HARQ) transmission over block fading channel. In our approach, the transmitter jointly encodes a variable number of bits for each round of HARQ. The parameters (rates) of this joint coding can vary and may be based on the negative acknowledgment (NACK ...

Adaptive HARQ (A-HARQ) for ultra-reliable communication in 5G [PDF]
, 2016 This thesis addresses the need for motivating applications, such as mission critical industrial control and medical applications, to operate under Ultra-Reliable Communication (URC) mode in future 5th generation (5G) cellular wireless networks, while also under strict Quality of Service (QoS) constraints such as ultra-low latency.

Fast-Decodable MIMO HARQ Systems [PDF]
IEEE Transactions on Wireless Communications, 2015 This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there exist two classes of fast-decodable MIMO HARQ systems: independent and dependent STBC structures.

Toward URLLC with Proactive HARQ Adaptation [PDF]
2022 Joint European Conference on Networks and Communications & 6G Summit (EuCNC/6G Summit), 2022 In this work, we propose a dynamic decision maker algorithm to improve the proactive HARQ protocol for beyond 5G networks. Based on Lyapunov stochastic optimization, our adaptation control framework dynamically selects the number of proactive retransmissions for intermittent URLLC traffic scenarios under time-varying channel conditions without ...

Subcode-Based Early HARQ for 5G [PDF]
2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018 Tactile Internet (TI) constitutes one of the major use cases for the development of the fifth generation (5G) mobile specification. TI services put high demand on the latency and reliability requirement, which is covered in the ultra-reliable low-latency communication (URLLC) discussion in 5G standardization.

A New Adaptive Rate IR-HARQ Combining with AMC [PDF]
Journal of Communications Software and Systems, 2018 In this paper, we analyze a new cross layer combining scheme of adaptive modulation and coding (AMC) at the physical layer and hybrid automatic repeat request (HARQ) protocol at the data link layer.
