Techniques for multiplexing sidelink feedback on a high priority physical uplink shared channel

An apparatus for wireless communication at a network device, comprising:

• one or more memories that store code;
• and
• one or more processors coupled with the one or more memories and configured to, in association with executing the code, cause the network device to:
• transmit, to a user equipment (UE), a first signal scheduling a first uplink data message via a physical uplink shared channel associated with a first priority index, the first uplink data message at least partially overlapping in time with an uplink control channel resource for feedback associated with sidelink communication at the UE;
• transmit, to the UE, a second signal indicating whether the feedback associated with the sidelink communication is able to be multiplexed with the first uplink data message in accordance with the physical uplink shared channel being associated with the first priority index;
• and
• receive, from the UE, the first uplink data message in accordance with 14 the second signal indicating whether the feedback associated with the sidelink communication is able to be multiplexed with the first uplink data message.

A method for wireless communication at a user equipment (UE), comprising:

• receiving, from a network device, a first signal that schedules a first uplink data message via a physical uplink shared channel associated with a first priority index, the first uplink data message at least partially overlapping in time with an uplink control channel resource for feedback associated with sidelink communication at the UE;
• obtaining a second signal that indicates whether the feedback associated with the sidelink communication is able to be multiplexed with the first uplink data message in accordance with the physical uplink shared channel being associated with the first priority index;
• and
• transmitting, to the network device, the first uplink data message in accordance with the second signal indicating whether the feedback associated with the sidelink communication is able to be multiplexed with the first uplink data message.

A method for wireless communication at a network device, further comprising:

• transmitting, to a user equipment (UE), a first signal scheduling a first uplink data message via a physical uplink shared channel associated with a first priority index, the first uplink data message at least partially overlapping in time with an uplink control channel resource for feedback associated with sidelink communication at the UE;
• transmitting, to the UE, a second signal indicating whether the feedback associated with the sidelink communication is able to be multiplexed with the first uplink data message in accordance with the physical uplink shared channel being associated with the first priority index;
• and
• receiving, from the UE, the first uplink data message in accordance with the second signal indicating whether the feedback associated with the sidelink communication is able to be multiplexed with the first uplink data message.
