    Abstract: A method of constructing a codebook with multiple resolution in a wireless communication system includes constructing, with a user equipment (UE), a high resolution codebook using a low resolution codebook; and transmitting, from the UE to a base station (BS), Channel State Information (CSI) feedback in accordance with a feedback scheme corresponding to the high resolution codebook or the low resolution codebook. The high resolution codebook defines the feedback scheme corresponding to the high resolution codebook.

The beamforming entity can transmit data signals using the first set of preferred transmission beams. Based on the decoding of the data signals, the remote device can provide a second indication to the beamforming entity identifying a second set of preferred transmission beams. The second set of preferred transmission beams can be a subset of the first set of preferred transmission beams. The beamforming entity can retransmit certain previously transmitted data signals using the second set of preferred transmission beams.
