Efficient resource allocation

An apparatus for wireless communication, the apparatus being a station (STA) or an access point (AP), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine a first subset of resource units (RUs) of a set of RUs that extends across a bandwidth of a channel in a transmission time period, the bandwidth comprising a plurality of tones, the plurality of tones including a number of direct current (DC) tones located at a central portion of the bandwidth, a first set of guard tones located at an upper outer edge portion of the bandwidth, and a second set of guard tones located at a lower outer edge portion of the bandwidth, the first subset of RUs including less RUs than the set of RUs, remaining RUs in the set of RUs other than the first subset of RUs being standard blocks, each RU of the set of RUs including at least 26 tones;
• and
• communicate at least one of data or control information in the first subset of the RUs,
• wherein the first subset of RUs includes x tones, and the x tones comprise a first set of x/2 tones with a frequency greater than the DC tones and less than the first set of guard tones and comprises a second set of x/2 tones with a frequency less than the DC tones and greater than the second set of guard tones,
• wherein:
• the first subset of RUs is a center block, the first set of x/2 tones is adjacent in frequency to the DC tones and the second set of x/2 tones is adjacent in frequency to the DC tones, or
• the first subset of RUs is an edge block, the first set of x/2 tones is adjacent in frequency to the first set of guard tones and the second set of x/2 tones is adjacent in frequency to the second set of guard tones.
