1. An apparatus for wireless communications by a user equipment (UE), comprising:
at least one memory comprising computer-executable instructions; and
one or more processors configured to execute the computer-executable instructions and cause the apparatus to:
obtain payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs);
determine a long sequence allocated to the UE, wherein the long sequence has a length greater than a number of tones in each RB, the long sequence is selected from a set of long sequences that allow for multiplexing with other UEs using the same interlace of the RBs, and each of the long sequences exhibits local orthogonality with other long sequences in the set; and
transmit the payload bits using a set of tones of the RBs and the long sequence allocated to the UE.
