Claim:
1. An apparatus for bandwidth allocation, comprising: at least one memory devices having instructions encoded thereon; and at least one processor coupled to the one or more memory devices and configured, by the instructions, to access information indicative of operating conditions of multiple client devices; and to schedule multiple orthogonal frequency division multiple access (OFDMA) tones for communication to at least one of the multiple client devices using at least a portion of the information, wherein the multiple OFDMA tones are arranged within a resource block having a spectral width of about 80 MHz, the resource block comprises one or more of (i) a channel having a spectral width of about 80 MHz, (ii) a first sub-channel having a spectral width of about 40 MHz, or (iii) a second sub-channel having a spectral width of about 20 MHz, and wherein the channel comprises a number of non-null OFDMA tones, a first number of null tones forming a first edge of the channel, a second number of null tones forming a second edge of the channel, and third number of null tones for direct current at about a center of the channel, and wherein the at least one processor is further configured, by the instructions, to select the multiple OFDMA tones from the non-null OFDMA tones.
