Leave a Comment / Uncategorized / By

Reference signals are unique signals only present in Physical channels and are used to deliver a reference point for resource scheduling during Uplink and downlink transmission. It occupies specific resource elements within the grid. NR constitutes of 4 reference signals i.e. DMRS(Demodulation Reference Signal) PTRS(Phase Tracking Reference Signal) CSI-RS(Channel State Information Reference Signal) SRS(Sounding Reference …
