| Field | Description |
|---|---|
| sl-DiscardTimer-r16 ENUMERATED {ms3, ms10, ms20, ms25, ms30, ms40, ms50, ms60, ms75, ms100, ms150, ms200, ms250, ms300, ms500, ms750, ms1500, infinity} · OPTIONAL Cond Setup | Value in ms of discardTimer specified in TS 38.323 [5]. Value ms50 corresponds to 50 ms, value ms100 corresponds to 100 ms and so on. |
| sl-PDCP-SN-Size-r16 ENUMERATED {len12bits, len18bits} · OPTIONAL Cond Setup2 | PDCP sequence number size for unicast NR sidelink communication, 12 or 18 bits, as specified in TS 38.323 [5]. For groupcast and broadcast NR sidelink communication, only 12 bits is applicable, as specified in 9.1.1.5. |
| sl-OutOfOrderDelivery ENUMERATED { true } · OPTIONAL Need R since v16.1.0 | Indicates whether or not outOfOrderDelivery specified in TS 38.323 [5] is configured. This field should be either always present or always absent, after the radio bearer is established. |
