HIGH-EFFICIENCY WI-FI (HEW) STATION, ACCESS POINT, AND METHODS FOR RANDOM ACCESS CONTENTION

摘要

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 station may perform random access contention with other HEW stations for uplink resources for data transmission to the HEW AP. The HEW station may determine transmission activity during a first portion of a channel sensing period, and may select a sub-channel on which transmission activity is not determined. The HEW station may transmit an announcement signal on the selected sub-channel during a second portion of the channel sensing period. The announcement signal transmission may indicate, to other contending HEW stations, an intention by the HEW station to transmit on the same selected sub-channel during a subsequent access period.

1. A high-efficiency Wi-Fi (HEW) station comprising hardware processing circuitry configured to:
during a first portion of a channel sensing period, determine transmission activity for a group of sub-channels; during a second portion of the channel sensing period, transmit an announcement signal on a sub-channel selected from the group of sub-channels, the selection based at least partly on the transmission activity during the first portion; and during an access period, transmit an access signal on the same sub-channel selected for the transmission of the announcement signal, wherein the access signal includes an identifier of the HEW station, wherein the channel sensing period and the access period are allocated for resource contention by HEW stations for data transmissions to an access point (AP) on the group of sub-channels during a data transmission period.
