Abstract
Disclosed are a channel state feedback information determination method, a terminal, a base station and a communication system. The method includes that: a channel state is measured to form a measurement result; when a Rank Indicator (RI) is 2, a precoding matrix is formed according to the measurement result and a precoding codebook matrix model W; and channel state feedback information is formed according to the precoding matrix. The disclosure further discloses a computer storage medium.
