- W3118994906 abstract "In the fifth generation of wireless mobile communications, physical channel structures have gained significant flexibility, ranging from subcarrier spacing to resource allocation structures for data and reference signals. One particular group of channels affected from this change is the physical uplink control channel (PUCCH), carrying various critical control information such as HARQ acknowledgements, scheduling requests (SR) and channel state information (CSI) reports. In this paper we use the flexibility coming from the 5G standards to investigate the relationship between channel parameters and the reliability of channel estimates in different PUCCH formats using demodulation reference signals. Due to the high reliability requirements of control channels, improvement of channel estimation is crucial. In this paper, least squares estimation and Wiener filtering methods are utilized for channel estimation and the performance evaluation results are presented." @default.
