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.

摘要： Embodiments of a user station (STA), access point (AP), and method for random access contention in a wireless network are generally described herein. The STA may receive, from the AP, a beacon frame for a beacon interval. The STA may further receive a first random access Trigger Frame (TF) that indicates a first allocation of channel resources for random access contention by STAs during a first uplink transmission period of the beacon interval. The beacon frame may include a transmission timing for the first random access TF and a first TF cascade type for the first random access TF. The first TF cascade type may indicate whether a next TF is a random access TF or a scheduled access TF.

The AP may further receive sounding feedback from at least some of the STAs during the sounding feedback period.
