Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for communication in a wireless network are generally described herein. In some embodiments, the HEW AP may transmit a resource allocation message to indicate an allocation of sub-channels to one or more HEW stations for uplink data transmissions. Information included in the resource allocation message may include various indicators related to full or partial allocation of the sub-channels and whether equal allocations are made for each of the HEW stations. A sub-channel mapping block may also be included to indicate how the sub-channels are assigned to the HEW stations. In some cases, the length of the sub-channel mapping block may vary based at least partly on the indicators included in the message.

Abstract: 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.
