Abstract:
A method of transmitting a codebook index in a wireless communication system includes receiving a feedback index regarding an entity selected from a plurality of entities belonging to a feedback codebook, selecting a precoder from a precoding codebook using the feedback index, the precoding codebook comprising a plurality of precoders and transmitting a precoder index of the selected precoder. Flexibility can be given to codebook designs, and overhead due to the feedback of codebook indices can be reduced.
