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 method further comprises selecting, with the UE, multiple first beams from multiple second beams used for downlink transmission from the BS. The constructing constructs the high resolution codebook based on the multiple first beams, and the low resolution codebook is constructed based on a single beam selection scheme that selects a single beam.

Abstract:
Systems and methods are provided to implement features in the IEEE 802.11ad+/ay protocols by utilizing combinations of analog and digital precoding (such as hybrid mmWave precoding) to enable multi-stream/multi-user transmissions. These systems and methods are also suitable for 5G wireless networks, such as found in 3GPP. These systems and methods address performing general precoder design, reducing of beam-training overhead with leak wave antennas, performing single-stage approximate precoding with enhanced SLS for SU-MIMO transmissions (eSLS1), performing multi-stage approximate precoding with enhanced SLS for SU-MIMO transmissions (eSLS2), and performing exact precoding with enhanced SLS for SU-MIMO transmissions.
Abstract:
Hybrid openloop and/or closedloop beamforming techniques are provided. A beamforming entity can transmit reference signals to a remote entity using a set of candidate transmission beams. The remote entity can provide a first indication to the beamforming entity identifying a first set of preferred transmission beams based on received reference signals. The first set of preferred transmission beams can be a subset of the set of candidate transmission beams. 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.
