SL-SyncConfig (SL-SyncConfig-r16)
SL-SyncConfig-r16 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE SL-SyncConfig specifies the configuration information concerning reception of synchronisation signals from neighbouring cells as well as concerning the transmission of synchronisation signals for sidelink communication.

| txParameters-r16 SEQUENCE { | |
| syncTxThreshIC-r16 SL-RSRP-Range-r16 · OPTIONAL Need R | Indicates the thresholds used while in coverage and out of coverage, respectively. Value 0 corresponds to -infinity, value 1 to -115 dBm, value 2 to -110 dBm, and so on (i.e. in steps of 5 dBm) until value 12, which corresponds to -60 dBm, while value 13 corresponds to +infinity. |

Value 0 corresponds to -infinity, value 1 to -115 dBm, value 2 to -110 dBm, and so on (i.e. in steps of 5 dBm) until value 12, which corresponds to -60 dBm, while value 13 corresponds to +infinity. |
| syncInfoReserved-r16 BIT STRING (SIZE (2)) · OPTIONAL Need R | Reserved for future use. |
| gnss-Sync-r16 ENUMERATED {true} · OPTIONAL Need R | If configured, the synchronization configuration is used for SLSS transmission/reception when the UE is synchronized to GNSS. If not configured, the synchronization configuration is used for SLSS transmission/reception when the UE is synchronized to eNB/gNB. |
