A data unit comprising bits to transmit over one or more frequency segments in a frequency range is obtained. An effective bandwidth in each frequency segment of the frequency range is determined, where the effective bandwidth excludes bandwidth of one or more punctured subchannels in a respective frequency segment. Bits are encoded based on the effective bandwidth of each frequency segment followed by parsing the encoded bits to one or more streams and parsing the encoded bits of a stream to the one or more frequency segments. The parsing of the encoded bits of the stream comprises allocating a first number of consecutive encoded bits to a first frequency segment and allocating a second number of consecutive encoded bits to a second frequency segment, wherein the first number and the second number are based on the effective bandwidth of the first frequency segment and the second frequency segment. The encoded bits are modulated and mapped to subcarriers for transmission.
