Systems and methods for handling sidelink feedback signaling

A method of wireless communication, comprising:

• receiving, by a user equipment (UE) operating as a transmitter UE of a sidelink communication link, sidelink feedback signaling from a UE operating as a receiver UE of the sidelink communication link;
• and
• implementing, by the transmitter UE, sidelink feedback signaling processing avoiding an impending collision with respect to forwarding the sidelink feedback signaling to a base station over a network communication link and other uplink signaling to the base station over the network communication link, wherein the implementing sidelink feedback signaling processing comprises:
• determining to drop or communicate the sidelink feedback signaling based at least in part on a sidelink data retransmission priority of a sidelink transmission.

An apparatus configured for wireless communication, comprising:

• a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the apparatus to:
• transmit, to a user equipment (UE) operating as a transmitter UE of a sidelink communication link with a UE operating as a receiver UE, signaling indicating a rule for the transmitter UE to determine whether to drop or communicate a sidelink feedback signaling from the receiver UE based at least in part on a sidelink data retransmission priority of a sidelink transmission, wherein the rule is based at least in part on avoiding an impending collision with respect to forwarding the sidelink feedback signaling to a base station over a network communication link and other uplink signaling to the base station over the network communication link;
• and
• receive, from the transmitter UE, the sidelink feedback signaling or the other uplink signaling based at least in part on the rule.
