Uplink control information repetition multiplexing with uplink shared channel communications

A method for wireless communication at an access network entity, comprising:

• determining that a first repetition of a control information communication from a user equipment (UE) is to be received in a first uplink communication, and that a second repetition of the control information communication is to be received in a second uplink communication from the UE, wherein the first uplink communication uses first transmission parameters that are provided for a first physical uplink shared channel (PUSCH) resource and the second uplink communication uses second transmission parameters that are provided for a second PUSCH resource, and wherein the first transmission parameters include one or more of a different modulation and coding scheme or a different number of transmission layers than the second transmission parameters;
• determining, based at least in part on the first transmission parameters and the second transmission parameters, a number of resource elements for each of the first repetition and the second repetition of the control information communication such that each of the first repetition and the second repetition have a same number of coded bits;
• buffering received signals from the determined number of resource elements of the first repetition in a soft combining buffer;
• adding received signals from the determined number of resource elements of the second repetition to the soft combining buffer;
• and
• decoding the buffered signals in the soft combining buffer to determine the control information communication.

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more processors,
• one or more memories coupled with the one or more processors;
• and
• instructions stored in the one or more memories and executable by the one or more processors to cause the apparatus to:
• determine that a first repetition of a control information communication is to be transmitted in a first uplink communication, and that a second repetition of the control information communication is to be transmitted in a second uplink communication, wherein the first uplink communication uses first transmission parameters that are provided for a first physical uplink shared channel (PUSCH) resource and the second uplink communication uses second transmission parameters that are provided for a second PUSCH resource, and wherein the first transmission parameters include one or more of a different modulation and coding scheme or a different number of transmission layers than the second transmission parameters;
• determine, based at least in part on the first transmission parameters and the second transmission parameters, a number of resource elements for transmitting each of the first repetition and the second repetition of the control information communication such that each of the first repetition and the second repetition have a same number of coded bits;
• encode, based at least in part on the determined number of resource elements, the first repetition of the control information communication and the second repetition of the control information communication to generate an encoded first repetition and an encoded second repetition that each have the same number of coded bits;
• and
• transmit the first uplink communication with the encoded first repetition and the second uplink communication with the encoded second repetition.
