Feedback power control techniques for wireless communications systems

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

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive first downlink control information corresponding to a first group of downlink transmissions and second downlink control information corresponding to a second group of downlink transmissions;
• calculate a number of information bits for a feedback message comprising first feedback for one or more downlink transmissions of the first group and second feedback for one or more downlink transmissions of the second group, the number of information bits comprising first information bits of the first feedback and second information bits of the second feedback;
• identify a transmission power for the feedback message based at least in part on the calculated number of information bits;
• and
• transmit the feedback message comprising the first feedback and the second feedback using the identified transmission power.

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

• means for receiving first downlink control information corresponding to a first group of downlink transmissions and second downlink control information corresponding to a second group of downlink transmissions;
• means for calculating a number of information bits for a feedback message comprising first feedback for one or more downlink transmissions of the first group and second feedback for one or more downlink transmissions of the second group, the number of information bits comprising first information bits of the first feedback and second information bits of the second feedback;
• means for identifying a transmission power for the feedback message based at least in part on the calculated number of information bits;
• and
• means for transmitting the feedback message comprising the first feedback and the second feedback using the identified transmission power.

A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive first downlink control information corresponding to a first group of downlink transmissions and second downlink control information corresponding to a second group of downlink transmissions;
• calculate a number of information bits for a feedback message comprising first feedback for one or more downlink transmissions of the first group and second feedback for one or more downlink transmissions of the second group, the number of information bits comprising first information bits of the first feedback and second information bits of the second feedback;
• identify a transmission power for the feedback message based at least in part on the calculated number of information bits;
• and
• transmit the feedback message comprising the first feedback and the second feedback using the identified transmission power.
