Publication number: 20150156709Abstract: 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.Type: ApplicationFiled: October 17, 2014Publication date: June 4, 2015Inventors: Ashish Kumar Shukla, Alireza Raissinia, Zhifeng Cai, Santosh Paul Abraham

Publication number: 20140254408Abstract: 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.Type: ApplicationFiled: September 26, 2013Publication date: September 11, 2014Applicant: QUALCOMM IncorporatedInventors: Ashish Kumar Shukla, Naveen Pratap Singh, Shu Du, Qinghai Gao, Zhanfeng Jia, Vishnu Vardhan Bala Krishnan
