SYSTEM AND METHOD FOR CHANNEL STATUS INFORMATION FEEDBACK IN A WIRELESS COMMUNICATIONS SYSTEM THAT UTILIZES MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) TRANSMISSION |
摘要 |
A method for user equipment operation in a wireless communication system, the wireless communication system having an base station, the method comprising measuring a channel between the UE and the base station, determining a quantized estimate using a codebook to approximate the measured channel, computing an error measure for the quantized estimate and transmitting the error measure and the quantized estimate to the base station for use by the base station in reconstructing an actual channel vector.
