Problems solved by technology

However, in some configurations, the uplink scheduling method still requires the STA to compete with the AP for channel access
In other words, the AP will act as an additional STA trying to gain access to the transport medium, thereby affecting all STAs trying to gain access

Embodiment Construction

[0040] Now refer to the photo figure 1 to give various aspects of a wireless network. A wireless network (also referred to herein as a Basic Service Set (BSS)) 100 is shown having a number of wireless nodes, typically designated as access points 110, and a number of access terminals or stations (STAs) 120. Each wireless node is capable of receiving and / or transmitting. In the following detailed description, the term "access point" is used to designate a transmitting node for downlink communications, the term "access terminal" is used to designate a receiving node, and for uplink communications the term "access point" is used to designate a transmitting node. To designate a receiving node, the term "access terminal" is used to designate a transmitting node. However, those skilled in the art will readily appreciate that other terms or designations may be used for the access point and / or access terminal. For example, an access point may be called a base station, an eNode B (e...

Abstract

One of a normal acknowledgement (ACK) and block ACK may be selectively enabled for wireless transmissions using a Very High Throughput Physical Layer Protocol Data Unit (PPDU). At least one designated bit may be set in a Physical Layer header of the PPDU for transmission from a transmitter to a receiver to indicate an ACK type selected from at least at least two of a normal ACK, a Block ACK, or no ACK. The PPDU may be transmitted in a Very High Throughput frame to the receiver where the designated bit can be used to provoke a normal ACK or Block ACK response to the PPDU, depending on the bit value.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61 / 355,114, filed June 15, 2010, which application is hereby expressly incorporated by reference in its entirety. technical field [0003] In general terms, the present invention relates to an apparatus and method for acknowledgment from a station in a wireless local area network system. In particular, the present invention relates to a very high throughput acknowledgment and signaling mechanism for communicating acknowledgment policies for use by receiving stations. Background technique [0004] In order to address the increasing bandwidth demands required by wireless communication systems, different schemes have been developed to allow multiple user terminals to communicate with a single access point by sharing channel resources while achieving high data throughput. Multiple-Input Multiple-Output (MIMO) technology represents...
