AI Technical Summary
Current codebooks in massive MIMO systems limit transmission flexibility for terminal devices, restricting them to specific transmission forms like partial non-coherent or non-coherent transmission, despite having the capability for coherent transmission, which affects resource utilization.
A communication method and apparatus that utilizes a codebook with three types of precoding matrices: first-type, second-type, and third-type, allowing terminal devices to communicate in coherent, partial coherent, and non-coherent transmission forms, enhancing flexibility and resource utilization by indicating available precoding matrices through higher layer signaling.
Improves transmission flexibility for terminal devices, enabling them to meet diverse transmission requirements and optimize resource utilization by supporting multiple transmission forms, thereby reducing bit overheads and enhancing signal quality.
