Methods and apparatus for nr d2d urllc communication

An apparatus for wireless communications implemented at a user equipment (UE), comprising

• a transceiver;
• a memory;
• and
• at least one processor coupled to the memory and configured to
• transmit data associated with an ultra-reliable and low-latency communications (URLLC) communication in a first set of one or more portions of a wireless communication structure having a plurality of portions;
• and
• re-transmit the data associated with the URLLC communication in a second set of one or more portions of the wireless communication structure, wherein one or more slot structures of the wireless communication structure are defined by the plurality of portions, the first set of one or more portions is based on a first mini-slot structure, the second set of one or more portions is based on a second mini-slot structure, and a mini-slot structure is smaller than a slot structure.
