Abstract
Systems, apparatus, and methods to provide an indication of frequency resource unit (RU) allocation from a wireless access point (AP) to one or more station devices (STA) are disclosed. The AP may be configured to generate a protocol data unit including a high efficiency wireless (HEW) preamble that indicates the RU allocation corresponding to each of the STA. The indication of the RU allocation for each of the STA, as disclosed herein, may be encoded in fewer bits than providing a bitmap of the RU allocation for each of the STA. A predetermined RU pattern may be used to map RU (e.g., 26 tone units, 52 tone units, etc.) to a RU allocation index. This RU allocation pattern may be efficiently communicated to each of the STAs in the HEW preamble of the protocol data unit.
