WebThis paper analyzes the physical layer security performance of hybrid automatic repeat request (HARQ) systems with the assistance of an intelligent reflecting surface (IRS) and aims to reveal the primary factors that enhance PLS. First, closed-form expressions for the connection outage probability (COP) and secrecy outage probability (SOP) in HARQ with … WebThis work investigates HARQ buffer management by leveraging information-theoretic achievability arguments based on random coding. Specifical ly, standard HARQ schemes, namely Type-I, Chase Combining and Incremental Redundancy, are first studied under the assumpt ion of a finite-capacity HARQ buffer by considering both coded

Analysis and Optimization of HARQ for URLLC - arXiv

WebMar 31, 2024 · In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency. First, we analyzed some critical performance metrics, including connection outage probability (COP), secrecy outage probability (SOP) and … WebThe energy efficiency of the hybrid automatic repeat request (HARQ) system has also become a hot research field recently. In general, better energy efficiency can be achieved through longer transmission delay. Such energy–delay trade-off has been studied in [2, 3] for various situ-ations. For the chase combining HARQ (HARQ-CC) scheme with a how to open msv files
