End-to-end (E2E) network device update is required for the evolution from 5G Non-Stand-Alone (NSA) networking to Stand-Alone (SA) networking. In 5G NSA networking, the control plane functions are handled by the 4G LTE network, while the user plane functions are handled by the 5G NR network. In contrast, in 5G SA networking, the control plane and user plane functions are handled by the 5G NR network alone. So, to evolve from 5G NSA to 5G SA, all the network devices including Radio Access Network (RAN), Core Network (CN) and Transport Network (TN) need to be updated with 5G SA capable software and hardware.

It is important to note that 5G SA provides more flexibility, control and autonomy for network operation and management, However, it also requires a higher level of complexity and more resources to operate.

A 5G UE measures the signal-to-interference-and-noise ratio (SINR) at the cell-specific reference signal (CSI-RS) to report channel quality information such as the CQI, RI, and PMI to a gNodeB. The CSI-RS SINR is used to determine the modulation and coding scheme (MCS) index, which is then used by the gNodeB to select the modulation and code rate for the transport block.

CQI (channel quality indicator), RI (rank indicator), and PMI (precoding matrix indicator) are all parameters that are used to indicate the channel quality of the wireless link between a UE and a gNodeB in a 5G network. These parameters are reported by the UE to the gNodeB and are used to determine the optimal modulation and coding schemes for the downlink transmissions.

To report these parameters, the UE needs to measure the channel quality, the UE measures the SINR (Signal-to-Interference-plus-Noise Ratio) of specific signals to report the channel quality information.

An AAU is responsible for performing up/down conversion of spectrum, power amplification, signal filtering, and analog-to-digital/digital-to-analog conversion. It does not perform baseband data processing. This is stated in the official 3GPP documentation which states: "The AAU performs up/down conversion of spectrum, power amplification, signal filtering, and analog-to-digital/digital-to-analog conversion." Here is a link to the relevant 3GPP documentation for further reference: https://www.3gpp.org/dynareport/33222.htm
