Fields (10)
| Field | Description |
|---|---|
| sl-Freq-Id-r16 SL-Freq-Id-r16 since v16.1.0 | This field indicates the identity of the dedicated configuration information on the carrier frequency for NR sidelink communication. |
| sl-SCS-SpecificCarrierList-r16 SEQUENCE (SIZE (1..maxSCSs)) OF SCS-SpecificCarrier | A set of UE specific channel bandwidth and location configurations for different subcarrier spacings (numerologies). Defined in relation to Point A. The UE uses the configuration provided in this field only for the purpose of channel bandwidth and location determination. In this release, only one SCS-SpecificCarrier is allowed to be configured for NR sidelink communication. |
| sl-AbsoluteFrequencyPointA-r16 ARFCN-ValueNR · OPTIONAL Need M | Absolute frequency of the reference resource block (Common RB 0). Its lowest subcarrier is also known as Point A. |
| sl-AbsoluteFrequencySSB-r16 ARFCN-ValueNR · OPTIONAL Need R | Indicates the frequency location of sidelink SSB. The transmission bandwidth for sidelink SSB is within the bandwidth of this sidelink BWP. |
| frequencyShift7p5khzSL-r16 ENUMERATED {true} · OPTIONAL Cond V2X-SL-Shared | Enable the NR SL transmission with a 7.5 kHz shift to the LTE raster. If the field is absent, the frequency shift is disabled. |
| valueN-r16 INTEGER (-1..1) | Indicate the NR SL transmission with a valueN 5kHz shift to the LTE raster. (see TS 38.101-1 [15], clause 5.4E.2). |
| sl-BWP-ToReleaseList-r16 SEQUENCE (SIZE (1..maxNrofSL-BWPs-r16)) OF BWP-Id · OPTIONAL Need N | This field indicates the list of sidelink BWP(s) on which the NR sidelink communication configuration is to be released. |
| sl-BWP-ToAddModList-r16 SEQUENCE (SIZE (1..maxNrofSL-BWPs-r16)) OF SL-BWP-Config-r16 · OPTIONAL Need N | This field indicates the list of sidelink BWP(s) on which the NR sidelink communication configuration is to be added or reconfigured. In this release, only one BWP is allowed to be configured for NR sidelink communication. |
| sl-SyncConfigList-r16 SL-SyncConfigList-r16 · OPTIONAL Need M | |
| sl-SyncPriority-r16 ENUMERATED {gnss, gnbEnb} · OPTIONAL Need M | This field indicates synchronization priority order, as specified in clause 5.8.6. sl-SyncPriority is configured with the same value across all carrier frequencies configured for UEs performing NR sidelink communication on multiple carrier frequencies. |
