摘要： 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.

摘要： This disclosure describes systems, methods, and devices related to allocating non-continuous resource units (RUs). A device may determine a non-continuous RU allocation for one or more devices in a 80 MHz bandwidth including four 20 MHz channels, the non-continuous RU allocation including disabled tones of a 20 MHz channel of the four 20 MHz channels, and the disabled tones being a subset of tones within the 20 MHz channel. The device may determine a high efficiency wireless frame comprising an indication of the non-continuous RU allocation. The device may send the high efficiency wireless frame to one or more multiple devices.

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.
