摘　　要：Traditional wireless communication systems have extensively used far-field spatial resources.However,with the emergence of sixth-generation(6G)networks,the exploration and utilization of near-field resources have become imperative.These resources introduce novel physical spatial dimensions to wireless communication systems.By leveraging higher frequency bands—such as midband,millimeter-wave,and terahertz frequencies—and integrating technologies like reconfigurable intelligent surfaces(RISs),ultra-largescale multiple input multiple output(MIMO),and cellfree networks,near-field communication(NFC)is set to become a critical enabler for 6G networks.This paradigm shift challenges the conventional far-field plane wave assumptions,necessitating a reevaluation of strategies for spatial resource management.
