In this talk\, we present our recent progress and strategy toward th e standardization of AFDM for 6G. We first discuss how AFDM can be made ba ckward-compatible with existing 5G NR networks\, enabling a smooth evoluti on of the physical layer while preserving robustness in doubly-dispersive channels. We then show how the affine-domain structure of AFDM naturally s upports integrated sensing and communication (ISAC)\, offering a unified w aveform for joint delay–Doppler estimation and reliable data transmissio n. Finally\, we summarize our recent AFDM-related 3GPP standard contributi ons and outline key open challenges and future research directions on the path toward AFDM-based 6G air interfaces.\n\nBiography: Pei Xiao is a prof essor of Wireless Communications at the Institute for Communication System s\, home of 5GIC and 6GIC at the University of Surrey. He is the technical manager of 5GIC/6GIC\, leading the research team in the new physical laye r work area\, and coordinating/supervising research activities across all the work areas. He has published extensively in the fields of communicatio n theory\, RF and antenna design\, and signal processing for wireless comm unications. Professor Xiao’s research focuses on next-generation wireles s technologies\, with a specific emphasis on IoT applications\, satellite communications\, and high-mobility vehicular networks. A key aspect of his work involves innovative waveform designs for integrated sensing and comm unications (ISAC)\, which enable seamless integration of sensing and commu nication functionalities. His contributions have significantly reduced har dware complexity and enhanced radio resource utilization through advanced signal processing techniques. Additionally\, he has played a pivotal role in advancing sparse code multiple access (SCMA) systems\, driving improvem ents in connectivity and spectrum efficiency for 5G networks and beyond.\n \nWe look forward to your gracious presence.\nRegards\,\nIEEE ComSoc Stude nt Branch Chapter (SBC) Team\nIIT Guwahati\n\nBldg: EEE Department\, Semin ar Room \, IIT Guwahati\, Guwahati\, Assam\, India LOCATION:Bldg: EEE Department\, Seminar Room \, IIT Guwahati\, Guwahati\, A ssam\, India ORGANIZER:n.nabajyoti@iitg.ac.in SEQUENCE:15 SUMMARY:IEEE ComSoc Student Branch Chapter (SBC) and ComSoc\, IIT Guwahati Seminar Series: Invitation to a talk by Prof. Pei Xiao on 18th September\, 3 PM URL;VALUE=URI:https://events.vtools.ieee.org/m/577665 X-ALT-DESC:Description: <br /><div class="x_elementToProof" data-olk-copy-s ource="MessageBody">Dear All\,</div>\n<div class="x_elementToProof">Greeti ngs from the IEEE ComSoc Student Branch Chapter (SBC)\, IIT Guwahati&nbsp\ ; and ComSoc Chapter Guwahati.</div>\n<div class="x_elementToProof">We are pleased to have Professor Pei Xiao from the University of Surrey\, United Kingdom\, deliver a technical talk as per the details given below.</div>\ n<p class="x_elementToProof"><strong>Topic:&nbsp\;</strong>Affine Frequenc y Division Multiplexing for ISAC and NTN: Applications and Standardization Toward 6G<strong><br>Date:&nbsp\;</strong>18 September 2026 (Friday)<stro ng><br>Time:&nbsp\;</strong>3:00 PM &ndash\; 4:00 PM IST<strong><br>Mode:& nbsp\;</strong>Hybrid (Offline and Online via Microsoft Teams)<strong><br> Venue:&nbsp\;</strong>EEE Seminar Room\, Second Floor\, Dept. of EEE</p>\n <div class="x_elementToProof"><span class="x_spanWithBackgroundColor">&nbs p\;</span></div>\n<div class="x_elementToProof"><span class="x_spanWithBac kgroundColor">The abstract of the talk and a&nbsp\;brief bio of the speake r are given below:&nbsp\;</span></div>\n<div class="x_elementToProof"><str ong>&nbsp\;</strong></div>\n<div class="x_elementToProof"><strong>Abstract :&nbsp\;</strong>Affine Frequency Division Multiplexing (AFDM) has recentl y emerged as a promising waveform candidate for next-generation wireless c ommunications\, particularly in high-mobility environments such as V2X\, N TN\, and LEO satellite communications.
