Transmission of channel occupancy time-sharing information (COT-SI) reserving a COT for sidelink communications in unlicensed bands

A user equipment (UE), comprising:

• a memory;
• a transceiver;
• and
• at least one processor coupled to the memory and the transceiver, wherein the UE is configured to:
• perform a channel access procedure to acquire a current channel occupancy time (COT) and one or more future COTs in a sidelink channel over an unlicensed new radio (NR) band, wherein a number of the acquired COTs equals a difference between a maximum number of physical sidelink shared channel (PSSCH) reservations first stage sidelink control information (SCI-1) is configured to reserve and a number of one or more PSSCH reservations that the SCI-1 is configured to reserve;
• transmit, via the SCI-1, COT sharing information (COT-SI) indicating a structure of the current COT;
• and
• transmit a plurality of PSSCH reservations, with a first subset of the plurality of PSSCH reservations in the current COT and a second subset of the plurality of PSSCH reservations in the one or more future COTs.

A non-transitory computer-readable medium (CRM) having program code recorded thereon, the program code comprising:

• code for causing a user equipment (UE) to perform a channel access procedure to acquire a current channel occupancy time (COT) and one or more future COTs in a sidelink channel over an unlicensed new radio (NR) band, wherein a number of the acquired COTs equals a difference between a maximum number of physical sidelink shared channel (PSSCH) reservations a first stage sidelink control information (SCI-1) is configured to reserve and a number of one or more PSSCH reservations that the SCI-1 is configured to reserve;
• code for causing the UE to transmit, via the SCI-1, COT sharing information (COT-SI) indicating a structure of the current COT;
• and
• code for causing the UE to transmit a plurality of PSSCH reservations, with a first subset of the plurality of PSSCH reservations in the current COT and a second subset of the plurality of PSSCH reservations in the one or more future COTs.

A user equipment (UE), comprising:

• means for performing a channel access procedure to a current channel occupancy time (COT) and one or more future COTs in a sidelink channel over an unlicensed new radio (NR) band, wherein a number of the acquired COTs equals a difference between a maximum number of physical sidelink shared channel (PSSCH) reservations a first stage sidelink control information (SCI-1) is configured to reserve and a number of one or more PSSCH reservations that the SCI-1 is configured to reserve;
• means for transmitting, via the SCI-1, COT sharing information (COT-SI) indicating a structure of the current COT;
• and
• means for transmitting a plurality of PSSCH reservations, with a first subset of the plurality of PSSCH reservations in the current COT and a second subset of the plurality of PSSCH reservations in the one or more future COTs.
