description: Channel State Information (CSI) is a crucial parameter in the context of 5G New Radio (NR) technology. It refers to the information related to the channel state, which is essential for efficient communication between the User Equipment (UE) and the base station (gNB). CSI includes various parameters such as the Channel State Information Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS), and Sounding Reference Signal (SRS), among others. These parameters are used to estimate the channel state, which in turn helps in beamforming, precoding, and other advanced transmission techniques.
explanation: CSI is classified as a Parameter because it represents a set of information that characterizes the state of the communication channel between the UE and the gNB. This information is essential for optimizing the transmission and reception processes in 5G NR systems.
