Radio (nr) multicast feedback switching

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a first indication of a first resource configuration for a negative-acknowledgement (NACK) feedback mode;
• receiving a second indication of a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode;
• receiving a third indication indicating that the UE is to use one of the NACK feedback mode or the ACK/NACK feedback mode;
• receiving a multicast communication;
• and
• transmitting a NACK feedback for the multicast communication based on the first resource configuration if the third indication indicates that the UE is to use the NACK feedback mode, or transmitting an ACK feedback or a NACK feedback for the multicast communication based on the second resource configuration if the third indication indicates that the UE is to use the ACK/NACK feedback mode.

A user equipment (UE), comprising:

• means for receiving a first indication of a first resource configuration for a negative-acknowledgement (NACK) feedback mode;
• means for receiving a second indication of a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode;
• means for receiving a third indication indicating that the UE is to use one of the NACK feedback mode or the ACK/NACK feedback mode;
• means for receiving a multicast communication;
• and
• means for transmitting a NACK feedback for the multicast communication based on the first resource configuration if the third indication indicates that the UE is to use the NACK feedback mode, or transmitting an ACK feedback or a NACK feedback for the multicast communication based on the second resource configuration if the third indication indicates that the UE is to use the ACK/NACK feedback mode.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a user equipment (UE) to receive a first indication of a first resource configuration for a negative-acknowledgement (NACK) feedback mode;
• code for causing the UE to receive a second indication of a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode;
• code for causing the UE to receive a third indication indicating that the UE is to use one of the NACK feedback mode or the ACK/NACK feedback mode;
• code for causing the UE to receive a multicast communication;
• and
• code for causing the UE to transmit a NACK feedback for the multicast communication based on the first resource configuration if the third indication indicates that the UE is to use the NACK feedback mode, or transmitting an ACK feedback or a NACK feedback for the multicast communication based on the second resource configuration if the third indication indicates that the UE is to use the ACK/NACK feedback mode.
