Multi-transmitter scheduling using slot-based and sub-slot based physical sidelink shared channels

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

• receiving, from a base station (BS), a configuration indicating at least one subchannel within at least one subband;
• receiving, from another UE, a first transport block (TB) via a sub-PSSCH associated with a sub-slot;
• receiving, from the other UE, a second TB via a PSSCH associated with a slot;
• and
• performing blind decoding on a second-stage sidelink control information (SCI-2) in a subchannel within the at least one subband.

A user equipment (UE) comprising a transceiver, a memory, and a processor coupled to the transceiver and the memory, the UE configured to:

• receive a sub-slot resource pool (RP) configuration indicating a plurality of subchannels in an unlicensed subband;
• perform a clear channel assessment (CCA);
• transmit, to a first UE based on the CCA being successful, a first transport block (TB) in at least one subchannel of the plurality of subchannels via a first sub-PSSCH associated with a first sub-slot;
• and
• transmit, to at least one of the first UE or a second UE, a second TB via a PSSCH associated with a slot.

A user equipment (UE) comprising a transceiver, a memory, and at least one processor coupled to the transceiver and the memory, wherein the memory stores instructions that are executable by the at least one processor, individually or in any combination, to cause the UE to:

• receive, from a base station (BS), a configuration indicating at least one subchannel within at least one subband;
• receive, from another UE, a first transport block (TB) via a sub-PSSCH associated with a sub-slot;
• receive, from the other UE, a second TB via a PSSCH associated with a slot;
• and
• perform blind decoding on a second-stage sidelink control information (SCI-2) in a subchannel within the at least one subband.
