Title: Key Transmission Technologies for 6G Wireless Communications

Abstract:

This talk introduces AI empowered wireless communications, integrated sensing and communications (ISAC) and unified far-field and near-field MIMO for future 6G wireless systems. Specifically, the following key technologies are presented and summarized in detail: ①Millimeter-wave beam prediction and tracking methods with deep learning/reinforcement learning are proposed in order to reduce the overhead of beam management; ②Considering the inaccurate angular-delay port selection of Type-II codebook due to low signal-to-noise ratio (SNR) in uplink B5G wireless systems, an angular-delay port selection method with deep learning is proposed to mitigate the negative impact of noise and improve the sum-rate performance; ③Leveraging the state-of-the-art 3GPP OFDM waveform signals, additional sensing functions could be realized through orthogonal resource allocation and sequence design including cross-domain OFDM waveform design and Doppler-resilient sequence parameter optimization, while preserving the existing communication framework unchanged; ④The basic principle of unified far-field and near-field MIMO wireless systems is briefed.

Title: Exploring Optical Spectrum for 6G: From Optical Wireless to Petahertz Communications

With rapid deployment of 5G mobile networks, the research community has initiated discussions on the enabling technologies for 6G. This talk will overview the Optical Wireless Communication (OWC) technologies in the existing infrared, visible light as well as ultraviolet optical bands. It will present some key theoretical and experimental advances in OWC channel models, communication systems and networks, as well as applications in indoor, outdoor, and underwater scenarios. It will further introduce a new unified Petahertz Communication (PetaCom) framework to harmonize the fragmented optical bands, in order to enable strong system adaptation to the diverse terminals and environments. Finally it will address PetaCom challenges and point out potential applications in communication, positioning, control and sensing.
