Section: 16.9.9.5 Resource Allocation
Content: A UE using mode 2 resource allocation may support resource selection enhancements to avoid LBT blocking and increase COT resource utilization. If transmission in slot(s) before a reserved resource is able to share its initiated COT to the reservation, the UE may be (pre)configured to prioritize/select resource(s) in the slot(s) for transmission. To avoid blocking, a UE may avoid selection of a number of consecutive resources (up to UE implementation) before a reserved resource. Furthermore, a UE may avoid selection of a number of consecutive resources (up to UE implementation) after a reserved resource. A UE using mode 2 resource allocation supports resource selection for multiple consecutive slot transmission (MCSt). A UE autonomously determines whether to use MCSt, and the number of consecutive slots in an MCSt up to the maximum COT duration for a specific SL-CAPC as defined in TS 37.213[ Physical layer procedures for shared spectrum channel access ]  [37]. MCSt can be used for transmission of a single TB or multiple TBs. For each TB transmitted in an MCSt, the UE triggers resource (re)selection only when LBT failure is detected on the resources for the initial transmission and all retransmissions of the TB. When performing LCP procedure for transmission of multiple TBs in an MCSt, a UE may perform an enhanced LCP procedure as specified in TS 38.321[ NR; Medium Access Control (MAC) protocol specification ]  [6] based on the SL-CAPC used for LBT of the first TB.
