11.1 UE capability related constraints

36.3313GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Protocol specificationRadio Resource Control (RRC)Release 15TS

The following table lists constraints regarding the UE capabilities that E-UTRAN is assumed to take into account.

Parameter

Description

Value

NB-IoT

#DRBs

The number of DRBs that a UE shall support

8, 15

NOTE2

NOTE3

(0, 1, 2)

NOTE1

#RLC-AM

The number of RLC AM entities that a UE shall support

10, 17

(2, 3)

NOTE1

#minCellperMeasObjectEUTRA

The minimum number of neighbour cells (excluding black list cells) that a UE shall be able to store within a MeasObjectEUTRA. NOTE.

32

N/A

#minBlackCellRangesperMeasObjectEUTRA

The minimum number of blacklist cell PCI ranges that a UE shall be able to store within a MeasObjectEUTRA

32

N/A

#minCellperMeasObjectUTRA

The minimum number of neighbour cells that a UE shall be able to store within a MeasObjectUTRA. NOTE.

32

N/A

#minCellperMeasObjectGERAN

The minimum number of neighbour cells that a UE shall be able to store within a measObjectGERAN. NOTE.

32

N/A

#minCellperMeasObjectCDMA2000

The minimum number of neighbour cells that a UE shall be able to store within a measObjectCDMA2000. NOTE.

32

N/A

#minBlackCellperMeasObjectNR

The minimum number of blacklist cells that a UE shall be able to store within a MeasObjectNR

32

N/A

#minCellTotal

The minimum number of neighbour cells (excluding black list cells) that UE shall be able to store in total in all measurement objects configured

256

N/A

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.
