9.2.162 NR Radio Resource Status
36.4233GPPEvolved Universal Terrestrial Radio Access Network (E-UTRAN)Release 17TSX2 Application Protocol (X2AP)
The NR Radio Resource Status IE indicates the usage of the PRBs per cell for MIMO and per SSB area for all traffic in Downlink and Uplink and the usage of PDCCH CCEs for Downlink and Uplink scheduling.
