Spectral-Efficiency and Energy-Efficiency of Variable-Length XP-HARQ
Jiahui Feng, Zheng Shi, Yaru Fu +3
A variable-length cross-packet hybrid automatic repeat request (VL-XP-HARQ) is proposed to boost the spectral efficiency (SE) and the energy efficiency (EE) of communications. The…
Deep Reinforcement Learning Empowered Rate Selection of XP-HARQ
Da Wu, Jiahui Feng, Zheng Shi +3
The complex transmission mechanism of cross-packet hybrid automatic repeat request (XP-HARQ) hinders its optimal system design. To overcome this difficulty, this letter attempts to…
Outage Probability Analysis of HARQ-Aided Terahertz Communications
Ziyang Song, Zheng Shi, Qingping Dou +3
Although terahertz (THz) communications can provide mobile broadband services, it usually has a large path loss and is vulnerable to antenna misalignment. This significantly degrad…
Outage Performance of Cross-Packet HARQ
Jiahui Feng, Zheng Shi, Guanghua Yang +3
As opposed to hybrid automatic repeat request with incremental redundancy (HARQ-IR) that all the resources are occupied to resend the redundant information, cross-packet HARQ (XP-H…
