NOTE: In case of CGI reporting, the limit regarding the cells E-UTRAN can configure includes the cell for which the UE is requested to report CGI i.e. the amount of neighbour cells that can be included is at most (# minCellperMeasObjectRAT – 1), where RAT represents EUTRA/UTRA/GERAN/CDMA2000 respectively. NOTE 1: #DRBs based on UE capability, #RLC-AM =#DRBs + 2. NOTE 2: ’15’ applies when the UE supports extendedNumberOfDRBs-r15. For one MAC entity, the maximum number of DRBs configured with PDCP duplication and with RLC entity(ies) associated with this MAC entity is 8. NOTE 3: The requirement is applicable in EN-DC, NGEN-DC and LTE standalone. |
