Abstract: Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.

Abstract: Certain embodiments herein relate to an interleaver based on usable tones of a resource allocation. The interleaver is selected according to the number of usable tones and may be selected for each resource allocation to accommodate the variance in usable tones. The selected codebit interleaver or symbol interleaver may be a block interleaver in which bits are sequentially read in row by row and read out column by column, such that any unfilled entries in the block interleaver are skipped.
