Nr sidelink sci source and destination pruning

An apparatus for wireless communication at a second user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
• receive, from a first UE, a modified cyclic redundancy check (CRC) and a payload, wherein the modified CRC comprises CRC bits corresponding to the payload and source information and destination information associated with transmission of the payload;
• and
• compare the modified CRC with a list of source information and destination information to derive the CRC bits corresponding to the payload and the source information and the destination information associated with the transmission of the payload.

An apparatus for wireless communication at a first user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
• map to a payload one or more bits that correspond to source information and destination information associated with transmission of the payload;
• and
• transmit, to a second UE, the payload comprising the one or more bits that correspond to the source information and the destination information mapped to the payload.

• receive, from a first UE, a payload comprising one or more bits that correspond to source information and destination information mapped to the payload, wherein the source information and the destination information are associated with transmission of the payload;
• calculate a cyclic redundancy check (CRC) based on the payload received from the first UE, wherein the source information and the destination information mapped to the payload is excluded from the calculation of the CRC;
• and
• compare the source information and the destination information mapped to the payload with a list of source information and destination information in response to a CRC check pass of the CRC.
