SL-LBT-FailureRecoveryConfig (SL-LBT-FailureRecoveryConfig-r18)
SL-LBT-FailureRecoveryConfig-r18 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE SL-LBT-FailureRecoveryConfig-r18 is used to configure the parameters used for detection and cancellation of Sidelink consistent LBT failures for operation with shared spectrum channel access, as specified in TS 38.321 [3].

| Field | Description |
|---|---|
| sl-LBT-FailureInstanceMaxCount-r18 ENUMERATED {n4, n8, n16, n32, n64, n128, spare2, spare1} · OPTIONAL Need M since v18.2.0 | This field determines after how many LBT failure indications received from the physical layer the UE triggers sidelink LBT failure recovery (see TS 38.321 [3]). Value n4 corresponds to 4, value n8 corresponds to 8, and so on. |
| sl-LBT-FailureDetectionTimer-r18 ENUMERATED {ms10, ms20, ms40, ms80, ms160, ms320, spare2, spare1} · OPTIONAL Need M since v18.2.0 | Timer for consistent sidelink LBT failure detection (see TS 38.321 [3]). Value ms10 corresponds to 10 ms, value ms20 corresponds to 20 ms, and so on. |
| sl-LBT-RecoveryTimer-r18 ENUMERATED {ms10, ms20, ms40, ms80, ms160, ms320, spare2, spare1} · OPTIONAL Need M | Timer for consistent sidelink LBT failure cancellation (see TS 38.321 [3]). Value ms10 corresponds to 10 ms, value ms20 corresponds to 20 ms, and so on. |
