Aspects of the present disclosure provide techniques for multiplexing high priority uplink control information (UCI) and low priority UCI on a physical uplink control channel (PUCCH). A method includes determining a total number of resource blocks to transmit encoded UCI bits based on a quantized payload size of a second one or more encoded UCI bits of a second priority and a non-quantized payload size of a first one or more encoded UCI bits of a first priority. The method generally includes mapping the second one or more encoded UCI bits to a first number of resource elements associated with the quantized payload size and the first one or more encoded UCI bits to a second number of REs and transmitting the encoded UCI bits in a PUCCH in accordance with the mapping.
