Physical sidelink shared channel (PSSCH) resource allocation

A user equipment (UE) comprising:

• a processing system that includes one or more processors and one or more memory devices coupled with the one or more processors, the processing system configured to cause the UE to:
• select a layer of multiple layers of a layer structure, each layer including one or more nodes and associated with a bandwidth including multiple subchannels available for a physical sidelink shared channel (PSSCH) resource;
• allocate, based on the selected layer, a first portion of the bandwidth for a PSSCH;
• and
• initiate transmission, to a receive (RX) UE, of a physical sidelink control channel (PSCCH) that includes an indicator associated with the allocated first portion.

A user equipment (UE) comprising:

• a processing system that includes one or more processors and one or more memory devices coupled with the one or more processors, the processing system configured to cause the UE to:
• identify a subchannel group size of a group of subchannels, the group of subchannels associated with a bandwidth including multiple subchannels available for a physical sidelink shared channel (PSSCH) resource, wherein the multiple subchannels are divided into multiple subchannel groups, each subchannel group including one or more subchannels, in accordance with the subchannel group size;
• allocate, in accordance with the identified subchannel group size, a first portion of the bandwidth for a PSSCH;
• and
• transmit, to a receive (RX) UE, a physical sidelink control channel (PSCCH) that includes an indicator associated with the allocated first portion.
