Abstract
A method which i) segregates UEs to different categories of 'conforming' and “nonconforming”, and ii) performs rank indicator (RI) filtering and/or switching based on the specific category is provided. Rank indicator (RI) filtering is performed in a SINR-specific manner, e.g., when SINR is low, the rank filtering is performed in such a way to always give an output of 1 or 2, not more. In addition, the Modulation and Coding Scheme (MCS) assigned for a PDSCH is adjusted when the rank switching is performed, thereby achieving graceful rank switching. Furthermore, Outer Loop Rate Control (OLRC) optimization is provided in response to rank switching.
