1. A method of wireless communication, comprising:
obtaining, by a first wireless communication device, a physical uplink control channel (PUCCH) multiplex configuration, the PUCCH multiplex configuration including a orthogonal cover code (OCC) sequence of M values represented by w(m), where m varies from 1 to M;
communicating, by the first wireless communication device with a second wireless communication device, a grant indicating a frequency interlace, wherein the frequency interlace comprises a plurality of resource blocks spaced from each other by at least one other resource block in a shared radio frequency band, wherein the PUCCH multiplex configuration indicates a configuration for multiplexing PUCCH signals in the frequency interlace;
for each m, multiplying w(m) by x(n) for a plurality, N, of indices n to N to produce a multiplied sequence, where x(n) is associated with a sequence of N encoded format 3 data symbols;
concatenating each multiplied sequence to generate a first PUCCH signal; and
communicating, by the first wireless communication device with the second wireless communication device, the first PUCCH signal in one or more resource blocks of the frequency interlace based on the PUCCH multiplex configuration, wherein the first PUCCH signal comprises PUCCH format 3 data and wherein the PUCCH signal is based on:
the OCC sequence represented by w(m);
the sequence x(n); and
a discrete Fourier transform (DFT).
