Section: 5.8.9.1a.6.2 Additional Sidelink RLC Bearer addition/modification operation
Content: For the additional Sidelink RLC bearer, whose addition conditions are met as in clause 5.8.9.1a.6.1, the UE capable of NR sidelink communication that is configured by upper layers to perform NR sidelink communication shall: 1> for groupcast and broadcast; or 1> for unicast, if the additional Sidelink RLC bearer addition was triggered due to the reception of the RRCReconfigurationSidelink message; or 1> for unicast, for DRB, after receiving the RRCReconfigurationCompleteSidelink message, if the additional Sidelink RLC bearer addition was triggered due to the configuration received within the sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR or indicated by upper layers; or 1> for unicast, for SRB, after receiving the RRCReconfigurationCompleteSidelink message, if the additional Sidelink RLC bearer addition was decided by UE: 2> establish an additional RLC entity for NR sidelink communication and configure it in accordance with each sl-RLC-ConfigPC5 received in the RRCReconfigurationSidelink or sl-RLC-Config received in sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR for SL DRB, and as specified in clause 9.1.1.4 for SL SRB; 2> if this procedure was for Sidelink DRB: 3> if this procedure was due to the reception of a RRCReconfigurationSidelink message: 4> configure the MAC entity with a logical channel in accordance with the sl-MAC-LogicalChannelConfigPC5 received in the RRCReconfigurationSidelink associated with the sidelink RLC entity; 3> else if this procedure was due to the reception of a RRCReconfigurationCompleteSidelink message: 4> configure the MAC entity with a logical channel associated with the sidelink RLC entity, in accordance with the sl-MAC-LogicalChannelConfig received in the sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR; 3> else (i.e. for groupcast/broadcast): 4> configure the MAC entity with a logical channel associated with the sidelink RLC entity, in accordance with the sl-MAC-LogicalChannelConfig received in the sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR and assign a new LCID to this logical channel. 3> if the UE is in RRC_CONNECTED: 4> indicate the allowed carriers for the two RLC bearers of the DRB, as indicated in sl-AllowedCarriers, to lower layer; 3> else: 4> indicate the allowed carriers for the two RLC bearers of the DRB, decided by UE implementation, to lower layer, where the carrier indicated in sl-FreqInfoList is used for the RLC bearer if the SL-TxProfile of at least one associated QoS flow for the sl-ServedRadioBearer indicates backwardsCompatible; 2> else (i.e., if this procedure was for Sidelink SRB): 3> configure the MAC entity with a logical channel associated with the sidelink RLC entity, as specified in clause 9.1.1.4. 3> if the UE is in RRC_CONNECTED: 4> indicate the allowed carriers for the two RLC bearers of the SRB, as indicated in allowedCarrierFreqSet1/allowedCarrierFreqSet2, to lower layer; 3> else: 4> indicate the allowed carriers for the two RLC bearers of the SRB, decided by UE implementation, to lower layer, where the carrier indicated in sl-FreqInfoList is used for the RLC bearer if the SL-TxProfile of at least one associated QoS flow for the sl-ServedRadioBearer indicates backwardsCompatible; For the additional Sidelink RLC bearer, whose modification conditions are met as in clause 5.8.9.1a.6.1, the UE capable of NR sidelink communication that is configured by upper layers to perform NR sidelink communication shall: 1> for groupcast and broadcast; or 1> for unicast, if the additional Sidelink RLC bearer modification was triggered due to the reception of the RRCReconfigurationSidelink message; or 1> for unicast, after receiving the RRCReconfigurationCompleteSidelink message, if the additional Sidelink RLC bearer modification was triggered due to the configuration received within the sl-ConfigDedicatedNR, SIB12 or SidelinkPreconfigNR: 2> reconfigure the RLC entity of the sidelink DRB, in accordance with the sl-RLC-ConfigPC5 received in the RRCReconfigurationSidelink or sl-RLC-Config received in sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR, if included; 2> reconfigure the logical channel of the sidelink DRB, in accordance with the sl-MAC-LogicalChannelConfigPC5 received in the RRCReconfigurationSidelink or sl-MAC-LogicalChannelConfig received in sl-ConfigDedicatedNR, SIB12, SidelinkPreconfigNR, if included.
