42、lled by higher layers. ETSI ETSI TS 125 225 V15.0.0 (2018-07)83GPP TS 25.225 version 15.0.0 Release 154.1 General measurement concept L1 provides with the measurement specifications a toolbox of measurement abilities for the UE and the UTRAN. These measurements can be differentiated in different mea
43、surement types: intra-frequency, inter-frequency, inter-system, traffic volume, quality and internal measurements (see 14). In the L1 measurement specifications the measurements are distinguished between measurements in the UE (the messages will be described in the RRC Protocol) and measurements in
44、the UTRAN (the messages will be described in the NBAP and the Frame Protocol). To initiate a specific measurement the UTRAN transmits a measurement control message to the UE including a measurement ID and type, a command (setup, modify, release), the measurement objects and quantity, the reporting q
45、uantities, criteria (periodical/event-triggered) and mode (acknowledged/unacknowledged), see 14. When the reporting criteria is fulfilled the UE shall answer with a measurement report message to the UTRAN including the measurement ID and the results. In idle mode the measurement control message is b
46、roadcast in a System Information. Intra-frequency reporting events, traffic volume reporting events and UE internal measurement reporting events described in 14 define events which trigger the UE to send a report to the UTRAN. This defines a toolbox from which the UTRAN can choose the needed reporti
47、ng events. 4.2 Measurements for cell selection/reselection Whenever a PLMN has been selected the UE shall start to find a suitable cell to camp on, this is cell selection. When camped on cell the UE regularly searches for a better cell depending on the cell reselection criteria, this is called cell
48、reselection. The procedures for cell selection and reselection are described in 13 and the measurements carried out by the UE are explained in this specification. 4.3 Measurements for Handover For the handover preparation the UE receives from the UTRAN a list of cells (e.g. TDD, FDD or GSM).which th
49、e UE shall monitor (see monitored set in 14) in its idle timeslots. At the beginning of the measurement process the UE shall find synchronization to the cell to measure using the synchronization channel. This is described under cell search in 9 if the monitored cell is a TDD cell and in 4 if it is an FDD cell. For a TDD cell to monitor after this procedure the exact timing of the midamble of the P-CCPCH is known and the measurements can be performed. Depending on the UE implementation and if timing informa
