Analysis and simulation of aperiodically reported signaling in LTE uplink

This paper deals with the transmission of channel state information in the Long Term Evolution FDD - uplink mobile standard (Release 8), with focus on the possibility of aperiodical transmission of this information using Physical Uplink Shared Channel (PUSCH). It is necessary to ensure high quality transmission of feedback information about channel conditions between User Equipment (UE) and the Base Station (BS)in both directions. We present a complex analysis of signal processing of the control information transmitted aperiodically via PUSCH and a performance analysis. The simulation results prove robustness of the control information transmitted via PUSCH in various channel conditions and system settings and bring minimal required SNR values for reliable system operation according to 3GPP requirements.
