Early detection of forwarding for multi-hop ultra-reliable low latency communications

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

• at least one processor,
• at least one memory coupled with the at least one processor;
• and
• instructions stored in the at least one memory and executable by the at least one processor to cause the apparatus to:
• transmit, to a second UE, a capability notification, the capability notification indicating that the first UE is capable of forwarding, to the second UE, a coded data packet without the first UE decoding a data portuion of the coded data packet;
• receive the coded data packet in a millimeter wave frequency band;
• detect a radio network temporary identifier scrambling code for the coded data packet, wherein the radio network temporary identifier scrambling code indicates that the coded data packet is addressed to the second UE;
• and
• forward the coded data packet to a second UE based at least in part on the detected radio network temporary identifier scrambling code.

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

• means for transmitting, to a second UE, a capability notification, the capability notification indicating that the first UE is capable of forwarding, to the second UE, a coded data packet without the first UE decoding a data portion of the coded data packet;
• means for receiving the coded data packet in a millimeter wave frequency band;
• means for detecting a radio network temporary identifier scrambling code for the coded data packet, wherein the radio network temporary identifier scrambling code indicates that the coded data packet is addressed to the second UE;
• and
• means for forwarding the coded data packet to a second UE based at least in part on the detected radio network temporary identifier scrambling code.

A non-transitory computer-readable medium storing code for wireless communications at a first user equipment (UE), the code comprising instructions executable by at least one processor to:

• transmit, to a second UE, a capabity notification, the capability notification indicating that the first UE is capable of forwarding, to the second UE, a coded data packet without the first UE decoding a data portion of the coded data packet;
• receive the coded data packet in a millimeter wave frequency band;
• detect a radio network temporary identifier scrambling code for the coded data packet, wherein the radio network temporary identifier scrambling code indicates that the coded data packet is addressed to the second UE;
• and
• forward the coded data packet to the second UE based at least in part on the detected radio network temporary identifier scrambling code.
