Abstract:
A user equipment can be configured to decompose a multiple input multiple output (MIMO) channel into multiple domains, measure the channel state information reference signal (CSI-RS) for each domain, and select a feedback format for transmission to network node based on the measurements. The network node can use the feedback to determine transmission parameters to be transmitted to the user equipment.
