Uplink control information mapping on a shortened uplink shared channel

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

• identifying that a shortened physical uplink shared channel (sPUSCH) includes two data symbols;
• selecting a mapping rule for the sPUSCH based at least in part on the identifying;
• mapping acknowledgement (ACK/NACK) data to resource elements (REs) within the sPUSCH according to the selected mapping rule and based at least in part on a fixed starting position of the ACK/NACK data;
• and
• transmitting the ACK/NACK data via the sPUSCH.

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 number of data symbols included in a shortened physical uplink shared channel (sPUSCH);
• select a mapping rule for the sPUSCH based at least in part on the identified number of data symbols;
• determine a number of resource elements (REs) associated with the number of data symbols;
• map acknowledgement (ACK/NACK) data to one or more REs of the number of REs according to the selected mapping rule and based at least in part on the number of REs;
• and
• transmit the ACK/NACK data via the sPUSCH.
