Section: 5.8.9.1a.6.1 Additional Sidelink RLC Bearer addition/modification conditions
Content: For NR sidelink communication, additional sidelink RLC bearer addition is initiated only in the following cases: 1> for unicast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerToAddModList in the RRCReconfigurationSidelink for a slrb-PC5-ConfigIndex; or 1> for groupcast and broadcast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerToAddModListSizeExt in sl-ConfigDedicatedNR for a sl-ServedRadioBearer, and if the SL-TxProfile of all associated QoS flow(s) for the sl-ServedRadioBearer indicates backwardsIncompatible; or 1> for groupcast and broadcast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerToAddModListSizeExt in sl-ConfigDedicatedNR for a sl-ServedRadioBearer, and if the SL-TxProfile of at least one associated QoS flow for the sl-ServedRadioBearer indicates backwardsCompatible and UE decides to use PDCP duplication; or 1> for unicast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerToAddModListSizeExt in sl-ConfigDedicatedNR for a sl-ServedRadioBearer; or 1> for groupcast and broadcast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerConfigListSizeExt in SIB12 or in SidelinkPreconfigNR for a sl-ServedRadioBearer, and if the SL-TxProfile of all associated QoS flow(s) for the sl-ServedRadioBearer indicates backwardsIncompatible; or 1> for groupcast and broadcast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerConfigListSizeExt in SIB12 or in SidelinkPreconfigNR for a sl-ServedRadioBearer, and if the SL-TxProfile of at least one QoS flow for the sl-ServedRadioBearer indicates backwardsCompatible and UE decides to use PDCP duplication; or 1> for unicast, for sidelink DRB, if SL-RLC-BearerConfig is received in sl-RLC-BearerConfigListSizeExt in SIB12 or in SidelinkPreconfigNR for a sl-ServedRadioBearer, and if both UEs support PDCP duplication; or 1> for unicast, for sidelink SRB, if UE decides to use PDCP duplication; For NR sidelink communication, additional sidelink RLC bearer modification is initiated only in the following cases: 1> if any of the additional sidelink RLC bearer related parameters is changed by sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR or RRCReconfigurationSidelink for one additional sidelink RLC bearer, which is established;
