When integrated with drones, the combination offers ubiquitous deployment services in communication\u2010constrained areas. However, the limited battery life of drones hampers their performance. To address this, we introduce an innovative energy harvesting (EH), that is, EH\u2010RIS. EH\u2010RIS strategically divides passive reflection arrays across geometric space, improving EH and information transformation (IT). Employing a meticulous, exhaustive search algorithm, the resources of the drone\u2010RIS system are dynamically allocated across time and space to maximize harvested energy while ensuring optimal communication quality. Deep reinforcement learning (DRL) is employed to investigate drone\u2010RIS performance by intelligently allocating resources for EH and signal reflection. The results demonstrate the effectiveness of the DRL\u2010based EH\u2010RIS simultaneous wireless information and power transfer (SWIPT) system, demonstrating enhanced drone\u2010RIS spectrum\u2010efficient communication capabilities. Our investigation is summarized in unleashing potential, which shows how DRL and EH\u2010RIS work together to optimize drone\u2010RIS for next\u2010generation wireless networks.<\/jats:p>","DOI":"10.1049\/2024\/9548468","type":"journal-article","created":{"date-parts":[[2024,11,22]],"date-time":"2024-11-22T06:24:00Z","timestamp":1732256640000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Deep Reinforcement Learning Explores EH\u2010RIS for Spectrum\u2010Efficient Drone Communication in 6G"],"prefix":"10.1049","volume":"2024","author":[{"given":"Farhan M.","family":"Nashwan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8166-6127","authenticated-orcid":false,"given":"Amr A.","family":"Alammari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6437-2116","authenticated-orcid":false,"given":"Abdu","family":"saif","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2857-6979","authenticated-orcid":false,"given":"Saeed Hamood","family":"Alsamhi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2024,11,22]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12652-020-02521-x"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/widm.1521"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2024.103610"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.telpol.2022.102327"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2023.3329472"},{"key":"e_1_2_10_6_2","doi-asserted-by":"crossref","unstructured":"SaifA.
