Abstract
A method, system, and medium are provided for approximating an uplink sounding reference signal for a secondary radio-frequency channel associated with an eNodeB in a long-term-evolution (LTE) network deploying carrier aggregation. This is useful when the eNodeB does not have an uplink channel associated with the secondary RF channel. The approximated uplink sounding reference signal is utilized by the eNodeB to determine downlink beamforming weights for the secondary RF channel.
