User equipment shift randomization for uplink control channel transmission

An apparatus for wireless communication, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a base sequence for transmission of an uplink control message;
• receive signaling that indicates a user equipment (UE)-specific initial shift to be used with the base sequence;
• determine uplink control information for the uplink control message;
• determine a shifted sequence of the base sequence based at least in part on the UE-specific initial shift and the uplink control information;
• and
• transmit the uplink control information in the uplink control message, wherein the uplink control information is based at least in part on the shifted sequence.

An apparatus for wireless communication, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, to a user equipment (UE), signaling that indicates a UE-specific initial shift to be applied to a base sequence for transmission of an uplink control message;
• and
• receive uplink control information in the uplink control message, wherein the uplink control information is based at least in part on a shifted sequence that is shifted with respect to the base sequence in accordance with the UE-specific initial shift and a payload of the uplink control information.
