Enhanced internet of things relay data re-transmission

A base station (BS), comprising:

• a memory storing instructions;
• a transceiver;
• and
• one or more processors coupled with the memory and the transceiver, and configured to execute the instructions to:
• receive, via the transceiver, data from a relay user equipment (UE);
• transmit, via the transceiver, at least one negative acknowledgement (NACK) relating to the data, to the relay UE, indicating an unsuccessful reception of the data by the BS;
• and
• receive, via the transceiver, at least one of one or more redundant equivalent versions of the data from the relay UE.

A non-transitory computer readable medium including instructions that, when executed by one or more processors of a base station (BS), cause the one or more processors to:

• receive data from a relay user equipment (UE);
• transmit at least one negative acknowledgement (NACK) relating to the data, to the relay UE, indicating an unsuccessful reception of the data by the BS;
• and
• receive at least one of one or more redundant equivalent versions of the data from the relay UE.
