|
ab-Enabled Value TRUE indicates that access barring is enabled for UEs connected to EPC. |
|
ab-Enabled-5GC Value TRUE indicates that access barring is enabled for UEs connected to 5GC. |
|
eutra-Bandwidth EUTRA system bandwidth. Value bw5or10 corresponds to bandwidth 5 or 10 MHz, value bw15or20 corresponds to bandwidth 15 or 20 MHz. If the value of eutra-Bandwidth is bw5or10 and rasterOffset is set to khz7dot5 or khz-7dot5, the E-UTRA system bandwidth is 5 MHz. If the value of eutra-Bandwidth is bw5or10 and rasterOffset is set to khz2dot5 or khz-2dot5, the E-UTRA system bandwidth is 10 MHz. If the value of eutra-Bandwidth is bw15or20 and rasterOffset is set to khz7dot5 or khz-7dot5, the E-UTRA system bandwidth is 15 MHz. If the value of eutra-Bandwidth is bw15or20 and rasterOffset is set to khz2dot5 or khz-2dot5, the E-UTRA system bandwidth is 20 MHz. When the E-UTRA system bandwidth is 5 MHz or 15 MHz, if the value of sib-GuardbandInfo is sib-GuardbandInbandSamePCI or sib-GuardbandinbandDiffPCI, the offset between the anchor carrier and the non-anchor carrier used for SIB1 and/or SI transmission is 45 kHz. |
|
eutra-CRS-SequenceInfo Information of the carrier containing NPSS/NSSS/NPBCH. Each value is associated with an E-UTRA PRB index as an offset from the middle of the LTE system sorted out by channel raster offset. See TS 36.211 [21] and TS 36.213 [23]. |
|
eutra-NumCRS-Ports, sib-eutra-NumCRS-Ports Number of E-UTRA CRS antenna ports, either the same number of ports as NRS or 4 antenna ports. See TS 36.211 [21], TS 36.212 [22], and TS 36.213 [23]. |
|
hyperSFN-LSB Indicates the 2 least significant bits of hyper SFN. The remaining bits are present in SystemInformationBlockType1-NB. |
|
operationModeInfo Deployment scenario (in-band/guard-band/standalone) and related information. See TS 36.211 [21] and TS 36.213 [23]. Inband-SamePCI indicates an in-band deployment and that the NB-IoT and LTE cell share the same physical cell id and have the same number of NRS and CRS ports. Inband-DifferentPCI indicates an in-band deployment and that the NB-IoT and LTE cell have different physical cell id. guardband indicates a guard-band deployment. standalone indicates a standalone deployment. When operationmodeInfo is set to guardband, if rasterOffset is set to khz-7dot5 or khz-2dot5, the guardband anchor carrier is at the higher edge of the LTE carrier. If rasterOffset is set to khz7dot5 or khz2dot5, the guardband anchor carrier is at the lower edge of the LTE carrier |
|
schedulingInfoSIB1 This field contains an index to a table specified in TS 36.213 [23], Table 16.4.1.3-5 or Table 16.4.1.3-7 when sib1-CarrierInfo is set to anchor or to non-anchor respectively, that defines SystemInformationBlockType1-NB scheduling information. If sib1-CarrierInfo is set to non-anchor, E-UTRAN configures a value between 0 and 7. |
|
sib-GuardbandGuardbandLocation Location of the non-anchor carrier used for SIB1 and/or SI transmission when operationmodeInfo is set to guardband and the non-anchor carrier is in guardband. See TS 36.213 [23]. Value same corresponds to the carrier adjacent to the anchor carrier on the outer side of the guardband, value opposite corresponds to the carrier closest to the edge of the LTE carrier in the opposite guardband. |
|
sib-GuardbandInfo Information of the carrier used for SIB1 and/or SI transmission when operationmodeInfo is set to guardband. See TS 36.213 [23]. sib-GuardbandAnchor indicates the anchor carrier. sib-GuardbandGuardband indicates a non-anchor carrier in guardband mode. sib-GuardbandInbandSamePCI or sib-GuardbandinbandDiffPCI indicates a non-anchor carrier in inband mode, and at the edge of the LTE carrier and on the same side as the anchor carrier. |
|
sib-InbandLocation Location of the non-anchor carrier used for SIB1 and/or SI transmission when operationmodeInfo is set to inband-SamePCI or inband-DifferentPCI, and sib1-CarrierInfo value and/or tdd-SI-CarrierInfo in SIB1-NB is set to non-anchor. See TS 36.213 [23]. Value lower corresponds to the lower adjacent carrier relative to the anchor carrier and value higher corresponds to the higher adjacent carrier relative to the anchor carrier. If both sib1-CarrierInfo value and tdd-SI-CarrierInfo value in SIB1-NB are set to anchor, the UE ignores sib-InbandLocation. |
|
sib-StandaloneLocation Location of the non-anchor carrier used for SIB1 and/or SI transmission when operationmodeInfo is set to standalone, and sib1-CarrierInfo value and/or tdd-SI-CarrierInfo in SIB1-NB is set to non-anchor. See TS 36.213 [23]. Value lower corresponds to the lower adjacent carrier relative to the anchor carrier and value higher corresponds to the higher adjacent carrier relative to the anchor carrier. If both sib1-CarrierInfo value and tdd-SI-CarrierInfo value in SIB1-NB are set to anchor, the UE ignores sib-StandaloneLocation. |
|
sib1-CarrierInfo Carrier used for SIB1 transmission. See TS 36.213 [23], clause 16.4.1.3. Value anchor corresponds to anchor carrier, value non-anchor corresponds to non-anchor carrier. |
|
systemFrameNumber-MSB Defines the 4 most significant bits of the SFN. As indicated in TS 36.211 [21], the 6 least significant bits of the SFN are acquired implicitly by decoding the NPBCH. |

drb-ContinueROHC This field indicates whether to continue or reset the header compression protocol context for the DRBs configured with the header compression protocol. Presence of the field indicates that the header compression protocol context continues when UE initiates UP-EDT in the same cell, while absence indicates that the header compression protocol context is reset. |
|
extendedWaitTime Value in seconds. |
|
extendedWaitTime-CPdata Wait time for data transfer using the Control Plane CIoT EPS optimisation. Value in seconds. See TS 24.301 [35]. |
|
noLastCellUpdate Presence of the field indicates that the last used cell for (G)WUS shall not be updated. |
|
redirectedCarrierInfo The redirectedCarrierInfo indicates a carrier frequency (downlink for FDD) and is used to redirect the UE to a NB-IoT carrier frequency, by means of the cell selection upon leaving RRC_CONNECTED as specified in TS 36.304 [4]. |
|
redirectedCarrierOffsetDedicated Parameter "Qoffsetdedicatedfrequency" in TS 36.304 [4]. For NB-IoT carrier frequencies, a UE that supports multi-band cells considers the redirectedCarrierOffsetDedicated to be common for all overlapping bands (i.e. regardless of the EARFCN that is used). |
