Techniques and apparatuses for avoiding collisions on an uplink data channel and a cell-specific or ue-specific uplink control channel

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

• determining one or more first resource elements to be used for a UE-specific uplink control channel associated with acknowledging or negatively acknowledging, by the UE, downlink data communications in an unlicensed radio frequency spectrum band;
• determining that the one or more first resource elements are scheduled to collide with one or more second resource elements scheduled for the UE for an uplink data transmission on an uplink data channel, wherein the uplink data transmission includes an initial uplink data transmission and one or more repetitions of the initial uplink data transmission;
• and
• deferring transmission of the uplink data transmission on the uplink data channel or multiplexing uplink control information (UCI) on the one or more second resource elements of the uplink data channel based at least in part on determining that the one or more first resource elements are scheduled to collide with the one or more second resource elements.

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

• memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• determine one or more first resource elements to be used for a cell-specific uplink control channel associated with acknowledging or negatively acknowledging initial network setup messages in an unlicensed radio frequency spectrum band;
• determine that the one or more first resource elements are scheduled to collide with one or more second resource elements scheduled for the UE for an uplink data transmission on an uplink data channel, wherein the uplink data transmission includes an initial uplink data transmission and one or more repetitions of the initial uplink data transmission;
• and
• modify the uplink data transmission based at least in part on determining that the one or more first resource elements are scheduled to collide with the one or more second resource elements.
