摘要：
Data in a mobile communications system is transmitted on at least one channel between at least one base station with multiple antennas and at least one user equipment. A base station applies precoding to the data based on a set of predefined codebooks. A first tracking mode with a first codebook from the set of predefined codebooks is used for the precoding, and at least a second tracking mode with at least a second codebook from the set of predefined codebooks is used for the precoding. The base station switches between the first tracking mode and the second tracking mode depending on at least one condition of the channel.
