Depletion of radio frequency resource due to traffic explosion is the serious problem on radio communication and multi antenna techniques which exploit spatial channel resource such as Single User (SU-) / Multi User (MU-) Multiple-Input Multiple Output (MIMO), coordinated multi cell operation, etc. are the promising solutions for these problems while these techniques heavily depend on the accuracy of channel estimation. When applying them to downlink communication, especially in case of Frequency Division Duplex (FDD) system, UE should estimate CSI based on downlink signal transmitted by BS and feed it back to BS using uplink resource. Consequently a trade-off between CSI accuracy and the overhead on uplink resource becomes a problem. Adaptive accuracy control can be a solution to the trade-off problem but the control scheme itself can be an additional overhead. To address the problem, in this report we focus on Analog CSI feedback method in which CSI is mapped directly onto the I/Q plane and show our preliminary results and its enhancement assuming OFDM system such as LTE-Advanced. |
