Abstract
Embodiments of system, device, and method configurations for implementing a progressive channel state indicator (CSI) evaluation are disclosed herein. In one example, techniques for increasing the precision of channel feedback information by detecting a best beam index in a progressively scanning grid of beams is deployed in a Long Term Evolution (LTE) network. The use of a progressive CSI technique may be used to improve the robustness of beamforming in network configurations deploying multi-user multiple input multiple output (MU-MIMO) transmission modes.
