Field	Description
sl-BWP-Id BWP-Id	An identifier for this sidelink bandwidth part.
sl-BWP-Generic-r16 SL-BWP-Generic-r16 · OPTIONAL Need M	This field indicates the generic parameters on the configured sidelink BWP.
sl-BWP-PoolConfig-r16 SL-BWP-PoolConfig-r16 · OPTIONAL Need M	This field indicates the resource pool configurations on the configured sidelink BWP.
sl-BWP-PoolConfigPS-r17 SetupRelease {SL-BWP-PoolConfig-r16} · OPTIONAL Need M since v17.0.0	This field indicates the resource pool configurations for power saving on the configured sidelink BWP. This field does not include sl-TxPoolExceptional .
sl-BWP-DiscPoolConfig-r17 SetupRelease {SL-BWP-DiscPoolConfig-r17} · OPTIONAL Need M since v17.0.0	This field indicates the NR sidelink discovery dedicated resource pool configurations on the configured sidelink BWP. The total number of Rx/Tx resource pools configured for communication and discovery does not exceed the maximum number of Rx/Tx resource pool for NR sidelink communication (i.e. maxNrofRXPool-r16/maxNrofTXPool-r16 ).
sl-BWP-PoolConfigA2X-r18 SetupRelease {SL-BWP-PoolConfig-r16} · OPTIONAL Need M since v18.0.0	This field indicates the resource pool configurations for A2X services on the configured sidelink BWP. This field does not include sl-TxPoolScheduling . This field does not include sl-TxPoolExceptional .
sl-BWP-PRS-PoolConfig-r18 SetupRelease {SL-BWP-PRS-PoolConfig-r18} · OPTIONAL Need M since v18.0.0	This field indicates the dedicated SL-PRS resource pool configurations for SL-PRS on the configured sidelink BWP. This field does not include sl-PRS-TxPoolExceptional . Dedicated SL-PRS resource pool is not expected to be configured in the slots colliding with the slots (pre)configured for any other resource pool(s) or S-SSB resource(s) in other SL carriers.
