| description | Extra-large scale MIMO (XL-MIMO) can meet the requirement of high spectral efficiency in 6G communication, but also faces the challenge caused by the increase in computational complexity.It is found that the unique spatial non-stationary characteristics of XL-MIMO channel brings new possibilities for low-complexity wireless transmission design.Firstly, starting from the near-field propagation effect, the research results of XL-MIMO channel characteristics analysis and channel modeling were combed, and the causes of spatial non-stationarity were deeply discussed.Furthermore, the concept of array visibility region (VR) in XL-MIMO was introduced, and the low-complexity wireless transmission design combined with VR information was discussed.Then, from the perspective of sub-array partition and distributed signal processing, the implementation of XL-MIMO low-complexity system architecture was introduced, and the corresponding design schemes were summarized.Finally, the future research direction was prospected. |
