Channel occupancy time sharing for sidelink communications

A first sidelink user equipment (UE) comprising:

• a memory;
• a transceiver;
• and
• at least one processor coupled to the memory and the transceiver, wherein the first sidelink UE is configured to:
• perform a listen-before-talk (LBT) procedure;
• acquire, based on the LBT procedure being successful, a channel occupancy time (COT);
• transmit a flag via sidelink control information indicating the first sidelink UE is sharing the COT, wherein the flag is transmitted in a physical sidelink feedback channel (PSFCH) communication;
• and
• transmit, to a second sidelink UE during the COT, COT sharing information for sharing the COT with the second sidelink UE, wherein sharing the COT with the second sidelink UE is based at least in part on the flag.

A non-transitory computer-readable medium having program code recorded thereon executable by one or more processors for wireless communication by a first sidelink user equipment (UE), the program code comprising:

• code for causing the first sidelink UE to perform a listen-before-talk (LBT) procedure;
• code for causing the first sidelink UE to acquire, based on the LBT procedure being successful, a channel occupancy time (COT);
• code for causing the first sidelink UE to transmit a flag via sidelink control information indicating the first sidelink UE is sharing the COT, wherein the flag is transmitted in a physical sidelink feedback channel (PSFCH) communication;
• and
• code for causing the first sidelink UE to transmit, to a second sidelink UE during the COT, COT sharing information for sharing the COT with the second sidelink UE, wherein sharing the COT with the second sidelink UE is based at least in part on the flag.
