Abstract: MAC layer frame aggregation and block acknowledgement are used in some WLAN technologies to improve efficiency of a communications channel by reducing PHY layer overhead. A frame aggregation window size defines how many MAC protocol data units (MPDUs) are included in an aggregated MPDU (AMPDU) frame. The frame aggregation window for a subsequent AMPDU frame is typically dependent upon the characteristics of the block acknowledgement—such as the number of non-acknowledged (NAK) MPDUs or the position of a hole in the previous AMPDU frame. A small frame aggregation window size may impact throughput especially at higher transmission rates. In this disclosure a transmission rate may be determined based, at least in part, on a projected frame aggregation window size resulting from a block acknowledgement. The frame aggregation feedback (e.g. block acknowledgement) may be used by a rate control module to determine a transmission rate that optimizes frame aggregation efficiency.
Abstract translation: 在一些WLAN技术中使用MAC层帧聚合和块确认，以通过减少PHY层开销来提高通信信道的效率。 帧聚合窗口大小定义在聚合MPDU（AMPDU）帧中包括多少MAC协议数据单元（MPDU）。 用于后续AMPDU帧的帧聚合窗口通常取决于块确认的特性，例如未确认（NAK）MPDU的数量或先前AMPDU帧中的孔的位置。 小帧聚合窗口大小可能会影响吞吐量，特别是在较高的传输速率下。 在本公开中，可以至少部分地基于由块确认产生的投影帧聚合窗口尺寸来确定传输速率。 帧聚合反馈（例如块确认）可以被速率控制模块用于确定优化帧聚合效率的传输速率。

Abstract: Methods and apparatus for independent basic service set based data paths for neighbor aware networks are described herein. In some aspects, an apparatus for wireless communication in an independent basic service set is provide. The apparatus comprises a receiver configured to receive a service discovery frame from a device in a neighbor aware network. The apparatus comprises a processor configured to determine a timing for an announcement traffic indication message window, wherein the timing is defined as an offset from a beginning of a discovery window for the neighbor aware network. The apparatus comprises a transmitter configured to transmit an announcement traffic indication message during the announcement traffic indication message window. The service discovery frame comprises an independent basic service set availability attribute defining a duration of the announcement traffic indication message window.

Abstract: A method and apparatus are disclosed for increasing the speed with which a number of stations associated with an IBSS network may be synchronized and/or for reducing the number of beacon frame collisions in the IBSS network. For at least some embodiments, the synchronization speed may be increased by allowing STAs having faster clock speeds to broadcast beacon frames more frequently than STAs having slower clock speeds.

Abstract: A first wireless station provides a configuration indication value that specifies a maximum number of medium access control layer service data units (MSDUs) that may be included in each medium access control layer protocol data unit (MPDU), or in each aggregated MPDU (A-MPDU), received by the first wireless station. A second wireless station receives the configuration indication value from the first wireless station, and in response, transmits only MSDUs (or A-MSDUs) having no more than the specified maximum number of MSDUs to the first wireless station. The configuration indication value can be included in various elements transmitted between the first and second wireless stations, including for example, a high throughput (HT) capabilities element, a very high throughput (VHT) capabilities information field, a VHT operation element or an add block acknowledge (ADDBA) response frame.

Abstract: Methods, apparatuses, and devices are described for wireless communications in which neighborhood area network (NaN) information may be requested and provided in a relatively fast and efficient manner between devices of a NaN. A wireless communication device, such as a station in a wireless communications network, may transmit an active probe request to seek information related to a NaN. The active probe request may be a NaN specific probe request, or may be transmitted from a station as part of an active scan for wireless network infrastructure other than NaN devices (e.g., as part of a scan for an AP in a BSS). An AP or master device of the NaN may receive the probe request and generate a NaN discovery response, which may include information that the requesting device may use for connecting to a device in the NaN.
Abstract translation: 描述了用于无线通信的方法，设备和设备，其中可以在NaN的设备之间以相对快速和有效的方式请求并提供邻域区域网络（NaN）信息。 诸如无线通信网络中的站的无线通信设备可以发送主动探测请求以寻求与NaN相关的信息。 主动探测请求可以是NaN特定探测请求，或者可以作为除NaN设备之外的无线网络基础设施的主动扫描的一部分（例如，作为对BSS中的AP的扫描的一部分）而从站发送。 NaN的AP或主设备可以接收探测请求并生成NaN发现响应，其可以包括请求设备可以用于连接到NaN中的设备的信息。
