The IEEE 802.11ax standard was designed to improve the reliability of connection and increase the throughput in dense Wi\u2010Fi scenario where the inter\u2010site interference becomes more serious and the spectral resources are more insufficient. Furthermore, in the next generation of Wi\u2010Fi standard IEEE 802.11be, the hybrid automatic repeat request (HARQ) and multi\u2010band technologies will be introduced to solve the problems of unstable delay, serious interference and insufficient spectrum resources. In this paper, retransmission schemes combined multi\u2010band and hybrid automatic repeat request are deeply studied to improve the retransmission efficiency. Combining hybrid automatic repeat request with multi\u2010band, this paper proposes three kinds of retransmission mode: insisting on the current frequency band (ICFB) retransmission, switching to the backup frequency band (SBFB) retransmission and concurrent retransmitting on dual\u2010band (CRDB). Then, an intelligent selection algorithm of retransmission mode based on machine learning is designed to determine the optimal mode. Theoretical analysis and experimental results show that the proposed method can greatly improve the retransmission efficiency and thereby reduce the transmission latency and increase the throughput for multi\u2010band Wi\u2010Fi networks.<\/jats:p>","DOI":"10.1049\/cmu2.12158","type":"journal-article","created":{"date-parts":[[2021,3,10]],"date-time":"2021-03-10T00:03:16Z","timestamp":1615334596000},"page":"1249-1258","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Intelligent hybrid automatic repeat request retransmission for multi\u2010band Wi\u2010Fi networks"],"prefix":"10.1049","volume":"15","author":[{"given":"Zhou","family":"Wang","sequence":"first","affiliation":[{"name":"The Provincial Key Laboratory of Information Coding and Transmission Southwest Jiaotong University  Chengdu Sichuan 610031 China"}]},{"given":"Xuming","family":"Fang","sequence":"additional","affiliation":[{"name":"The Provincial Key Laboratory of Information Coding and Transmission Southwest Jiaotong University  Chengdu Sichuan 610031 China"}]},{"given":"Li","family":"Yan","sequence":"additional","affiliation":[{"name":"The Provincial Key Laboratory of Information Coding and Transmission Southwest Jiaotong University  Chengdu Sichuan 610031 China"}]},{"given":"Rong","family":"He","sequence":"additional","affiliation":[{"name":"The Provincial Key Laboratory of Information Coding and Transmission Southwest Jiaotong University  Chengdu Sichuan 610031 China"}]},{"given":"Yan","family":"Long","sequence":"additional","affiliation":[{"name":"The Provincial Key Laboratory of Information Coding and Transmission Southwest Jiaotong University  Chengdu Sichuan 610031 China"}]}],"member":"265","published-online":{"date-parts":[[2021,3,9]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2018.2871099"},{"key":"e_1_2_7_3_1","unstructured":"IEEE Draft Standard for Information Technology \u2010 Telecommunications and Information Exchange Between Systems Local and Metropolitan Area Networks \u2010 Specific Requirements Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications Amendment Enhancements for High Efficiency WLAN.
