Abstract:
1. A channel information feedback method in a cellular system with finite feedback, comprising: allocating a number of channel information feedback bits to each channel of multiple channels dynamically according to quality of the channel, wherein against the averagely allocated number of channel information feedback bits, the number of channel information feedback bits allocated to a channel of higher quality is greater; determining size of a channel state information codebook of each channel according to the number of channel information feedback bits allocated to each channel dynamically, and generating a channel state information codebook; determining a feedback codeword in the channel state information codebook according to channel state information, wherein the feedback codeword is designed to feed back the channel state information; and sending a result of allocating the number of channel information feedback bits and sending an index number of the feedback codeword, wherein the index number is an identifier of the feedback codeword.
