Abstract (en)
[origin: KR20150044379A] Signal transmission/reception of mobile communications system terminals according to an embodiment of the present specification is made following the steps of: receiving reference signals from a base station; measuring channel information based on the received reference signal; predicting channel measurement errors based on the measured channel information; and transmitting feedback information created based on the prediction back to the base station. According to an embodiment of the present specification, stochastic channel precoding designing and stochastic user selection may maximize system throughputs by predicting errors caused by changes in channels over time, channel measurement errors, channel information quantization errors, and errors occurred during channel feedback.
