Abstract
Embodiments of the disclosure provide a system and method for providing channel feedback information (CFI) from a user equipment device to a base station. CFI is transmitted from the user equipment device on first and second communication channels. The user equipment device is operable to measure the channel rank of a downlink channel and to select a preferred channel rank that is used to configure the CFI that is transmitted to the base station. The base station is operable to use the preferred channel rank to interpret the CFI transmitted by the user end device.
