11 Increased minimum number of carriers to monitor

25.3003GPPGeneral descriptionRelease 17Stage 2TSUniversal Terrestrial Radio Access Network (UTRAN)

The increased number of carrier monitoring feature allows a UE to monitor more UMTS and LTE frequencies in all RRC states.

When increased carrier monitoring is used, the network signals whether a carrier should be measured with "reduced measurement performance" together with a scaling factor applicable for CELL_DCH and CELL_FACH states. In Idle mode, CELL_PCH and URA_PCH states a fixed scaling factor is used. When a carrier does not belong to the "reduced measurement performance" group, it belongs to the "normal measurement performance" group.

The value and the use of scaling factor are specified in [11].
