Systems and Methods for Wi-Fi High Efficiency Preambles for Resource Unit Allocation

摘要

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.

主权项

1. One or more non-transitory computer-readable media comprising computer-executable instructions that, when executed by one or more processors, configure the one or more processors to perform operations comprising:
identifying a first partial access identification (PAID) corresponding to a first station device (STA); identifying a second PAID corresponding to a second STA; determining a first resource unit (RU) to allocate to the first STA; determining a second RU to allocate to the second STA; generating a high efficiency wireless (HEW) preamble based at least in part on the first PAID, second PAID, an indication of the first RU allocation, and an indication of the second RU allocation, wherein the indication of the first RU allocation comprises a first RU allocation index, wherein the first RU allocation index identifies the first RU on a RU allocation pattern, wherein the indication of the second RU allocation comprises a second RU allocation index, and wherein the second RU allocation index identifies the second RU on the RU allocation pattern; and initiating transmission of the HEW preamble.
