Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a resource allocation method and device based on holographic multiple access. Background technique [0002] Next-generation wireless communications are expected to provide high-speed data services and support large-scale network access for a large number of mobile devices. This exponentially increasing demand for data transmission has led to the emergence of massive multiple-input multiple-output (MIMO) technologies and massive phased arrays. In a massive MIMO system based on Spatial Division Multiple Access (SDMA), the use of spatial diversity can significantly increase the system capacity. However, the inherent limitations of phased arrays seriously hinder the future development of massive MIMO systems because the components of phased arrays are expensive, such as phase shifters and high power consumption, especially at high frequency bands. In addition, the elem...
