Using a shared channel occupancy time across multiple sessions or casts

An initiator user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, individually or collectively configured to:
• transmit, to a responder UE, a channel occupancy time (COT) sharing information (COT-SI) indicating resources associated with a COT and one or more logical identifiers associated with the COT;
• and
• receive, from the responder UE, a transport block (TB) using the resources associated with the COT based at least in part on a mapping of a link identifier associated with the TB to a logical identifier indicated by the COT-SI.

A method of wireless communication performed by a responder user equipment (UE), comprising:

• receiving, from an initiator UE, a channel occupancy time (COT) sharing information (COT-SI) indicating resources associated with a COT;
• identifying that the initiator UE is a target of a transport block (TB) based at least in part on mapping a link identifier associated with the TB to a logical identifier indicated by the COT-SI;
• and
• transmitting the TB to the initiator UE using the resources associated with the COT based at least in part on identifying that the initiator UE is the target of the TB.
