What is quasi collocation?

One mode of operation is beam management with indica- tion, where a concept known as Quasi-co-location (QCL) is used to provide an instruction to the UE which it can use to adjust receiver settings. Different QCL types and relations were defined by 3GPP.

What does TCI stand for in 5G?

The beam management in 5G DL has been employing. a so-called transmission configuration indication. (TCI) signaling framework where a beam for a target. channel/signal (e.g., PDSCH, PDCCH, CSI-RS) to be. received by the UE can be indicated by a TCI.

What is csi-rs in 5G?

What is CSI-RS? Channel State Information Reference Signal (CSI-RS) is a reference signal (RS) that is used in the Downlink (DL) direction in 5G NR, for the purpose of Channel Sounding and used to measure the characteristics of a radio channel so that it can use correct modulation, code rate, beam forming etc.
