32、ers is briefly described to provide an understanding on how L1 measurements are initiated and controlled by higher layers. With the measurement specifications L1 provides measurement capabilities for the UE and NG-RAN. These measurements can be classified in different reported measurement types: int
33、ra-frequency, inter-frequency, inter-system, traffic volume, quality and UE internal measurements. In the L1 measurement definitions, see chapter 5, the measurements are categorised as measurements in the UE or measurements in the NG-RAN. 5 Measurement capabilities for NR In this chapter the physica
34、l layer measurements reported to higher layers are defined. 5.1 UE measurement capabilities The structure of the table defining a UE measurement quantity is shown below. Column field Comment Definition Contains the definition of the measurement. Applicable for States in which state(s) it shall be po
35、ssible to perform this measurement. The following terms are used in the tables: RRC_IDLE; RRC_INACTIVE; RRC_CONNECTED; Intra-frequency appended to the RRC state: Shall be possible to perform in the corresponding RRC state on an intra-frequency cell; Inter-frequency appended to the RRC state: Shall b

37、nal received power (SS-RSRP) Definition SS reference signal received power (SS -RSRP) is defined as the linear average over the power contributions (in W) of the resource elements that carry secondary synchronization signals (SS). The measurement time resource(s) for SS-RSRP are confined within SS/P
38、BCH Block Measurement Time Configuration (SMTC) window duration. If SS-RSRP is used for L1-RSRP as configured by reporting configurations as defined in 3GPP TS 38.214 6, the measurement time resources(s) restriction by SMTC window duration is not applicable. For SS-RSRP determination demodulation re
39、ference signals for physical broadcast channel (PBCH) and, if indicated by higher layers, CSI reference signals in addition to secondary synchronization signals may be used. SS-RSRP using demodulation reference signal for PBCH or CSI reference signal shall be measured by linear averaging over the po
40、wer contributions of the resource elements that carry corresponding reference signals taking into account power scaling for the reference signals as defined in 3GPP TS 38.213 5. If SS-RSRP is not used for L1-RSRP, the additional use of CSI reference signals for SS-RSRP determination is not applicabl
41、e. SS-RSRP shall be measured only among the reference signals corresponding to SS/PBCH blocks with the same SS/PBCH block index and the same physical-layer cell identity. If SS-RSRP is not used for L1-RSRP and higher-layers indicate certain SS/PBCH blocks for performing SS-RSRP measurements, then SS
42、-RSRP is measured only from the indicated set of SS/PBCH block(s). For frequency range 1, the reference point for the SS-RSRP shall be the antenna connector of the UE. For frequency range 2, SS-RSRP shall be measured based on the combined signal from antenna elements corresponding to a given receive
43、r branch. For frequency range 1 and 2, if receiver diversity is in use by the UE, the reported SS-RSRP value shall not be lower than the corresponding SS-RSRP of any of the individual receiver branches. Applicable for If SS-RSRP is used for L1-RSRP, RRC_CONNECTED intra-frequency. Otherwise, RRC_IDLE
44、 intra-frequency, RRC_IDLE inter-frequency, RRC_INACTIVE intra-frequency, RRC_INACTIVE inter-frequency, RRC_CONNECTED intra-frequency, RRC_CONNECTED inter-frequency NOTE 1: The number of resource elements within the measurement period that are used by the UE to determine SS-RSRP is left up to the UE
45、 implementation with the limitation that corresponding measurement accuracy requirements have to be fulfilled. NOTE 2: The power per resource element is determined from the energy received during the useful part of the symbol, excluding the CP. ETSI ETSI TS 138 215 V15.2.0 (2018-07)83GPP TS 38.215 v
46、ersion 15.2.0 Release 155.1.2 CSI reference signal received power (CSI-RSRP) Definition CSI reference signal received power (CSI-RSRP), is defined as the linear average over the power contributions (in W) of the resource elements that carry CSI reference signals configured for RSRP measurements with
47、in the considered measurement frequency bandwidth in the configured CSI-RS occasions. For CSI-RSRP determination CSI reference signals transmitted on antenna port 3000 according to 3GPP TS 38.211 4 shall be used. If CSI-RSRP is used for L1-RSRP, CSI reference signals transmitted on antenna ports 300
48、0, 3001 can be used for CSI-RSRP determination. For intra-frequency CSI-RSRP measurements, if the measurement gap is not configured, UE is not expected to measure the CSI-RS resource(s) outside of the active downlink bandwidth part. For frequency range 1, the reference point for the CSI-RSRP shall b
49、e the antenna connector of the UE. For frequency range 2, CSI-RSRP shall be measured based on the combined signal from antenna elements corresponding to a given receiver branch. For frequency range 1 and 2, if receiver diversity is in use by the UE, the reported CSI-RSRP value shall not be lower than the corresponding CSI-RSRP of any of the individual receiver branches.
