Abstract
A user equipment can be configured to evaluate a reference signal from a network node and determine channel state information comprising a format indicator, wherein the format indicator comprises a rank indicator and the channel state information spatial resolution type. The user equipment can transmit to the network node the channel state information, which can be decoded by a network node to determine transmission scheduling parameters to be transmitted to the user equipment.
