Definition

The IE LBT-FailureRecoveryConfig-r16 is used to configure the parameters used for detection of consistent uplink LBT failures for operation with shared spectrum channel access, as specified in TS 38.321 [3].

LBT-FailureRecoveryConfig-r16 ::=    SEQUENCE {
    lbt-FailureInstanceMaxCount-r16      ENUMERATED {n4, n8, n16, n32, n64, n128},
    lbt-FailureDetectionTimer-r16        ENUMERATED {ms10, ms20, ms40, ms80, ms160, ms320},
    ...
}

FieldDescription
lbt-FailureInstanceMaxCount-r16
ENUMERATED {n4, n8, n16, n32, n64, n128}
since v16.1.0
This field determines after how many LBT failure indications received from the physical layer the UE triggers uplink LBT failure recovery (see TS 38.321 [3]). Value n4 corresponds to 4, value n8 corresponds to 8, and so on.
lbt-FailureDetectionTimer-r16
ENUMERATED {ms10, ms20, ms40, ms80, ms160, ms320}
since v16.1.0
Timer for consistent uplink LBT failure detection (see TS 38.321 [3]). Value ms10 corresponds to 10 ms, value ms20 corresponds to 20 ms, and so on.
