RRC Level RRC PDU Basic Production Padding FIGURE 6-28 Creation of RRC PDUs Measurement commands are used by E-UTRAN to order the UE to start measurements, modify measurements, or stop measurements. The reporting criteria that are used include event-triggered reporting, periodic reporting, and event-triggered periodic reporting. In E-UTRAN RRC_CON- NECTED state, network-controlled UE-assisted handovers are performed and various DRX cycles are supported. In E-UTRAN RRC_IDLE state, cell reselections are performed and DRX is supported. The UE reports measurement information in accordance with the measurement configuration as provided by E-UTRAN. E-UTRAN provides the measurement configuration applicable for a UE in RRC_CONNECTED by means of dedicated signaling. The UE may be requested to perform the following types of measurements: Intra-Frequency Measurements: measurements at the downlink carrier frequency of the serving cell; Inter-frequency measurements: measurements at frequencies that differ from the downlink carrier frequency of the serving cell; Inter-RAT measurements of UTRA frequencies; Inter-RAT measurements of GERAN frequencies; Inter-RAT measurements of cdma2000 HRPD or cdma2000 1xRTT frequencies. The measurement configuration includes the following parameters: Measurement Objects: the objects on which the UE performs the measurements. For intra- frequency and inter-frequency measurements, a measurement object is a single E-UTRA carrier frequency. Associated with this carrier frequency, E-UTRAN can configure a list of cell-specific offsets and a list of blacklisted cells. The blacklisted cells are not considered in event evaluation or measurement reporting. For inter-RAT UTRA measurements, a measurement object is a set of cells on a single UTRA carrier frequency. For inter-RAT GERAN measurements, a measurement object is a set of GERAN carrier frequencies. For inter-RAT cdma2000 measurements, a measurement object is a set of cells on a single (HRPD or 1xRTT) carrier frequency. Reporting Configurations: a l
