Patent number: 9137738Abstract: A method of transmitting management information, performed by an access point (AP), in a wireless local area network system. The method according to one embodiment includes transmitting, to a station, a frame including a basic service set (BSS) load information element, the BSS load information element including a multi user (MU) multiple input multiple output (MIMO) capable station (STA) count field and a plurality of bandwidth utilization fields. The MU-MIMO capable STA count field indicates a total number of STAB with MU reception capability currently associated with a candidate BSS managed by the AP. Each of the plurality of bandwidth utilization fields includes information about time that each corresponding channel width is busy.Type: GrantFiled: November 29, 2011Date of Patent: September 15, 2015Assignee: LG Electronics Inc.Inventors: Dae Won Lee, Yong Ho Seok

Patent number: 9131509Abstract: In a wireless communication network, to reduce the polling overhead it is proposed to poll several stations using the same polling frame. In order to be able to poll more than one station in the same frame, an access point can make use of the locations of stations relative to the access point. The location of each station relative to the access point will cause a different propagation delay for radio communications between the station and the access point. Based on the propagation delays, two or more stations may be grouped together for subsequent transmissions to the access point.Type: GrantFiled: April 5, 2013Date of Patent: September 8, 2015Assignee: CAMBIUM NETWORKS LIMITEDInventors: Mohammad Isam Malkawi, Ashraf Nusairat, Basman Dahleh

Patent number: 9113476Abstract: A method for performing wireless communication in a data-collection system includes a) listening whether a channel is free or busy and if the channel is free, transmitting; b) if the channel is busy, generating a random number and associating therewith a first interval of time to determine the instant of the start of transmission and further whether said channel is busy, identifying a second variable interval of time, monitoring the data exchanged in said channel with other devices that occupy the channel, queuing a third interval of time obtained from said first interval of time onto said second interval of time and transmitting at the end of said third interval of time. The second interval of time has a duration that is equal to the time wherein the channel remains in busy status.Type: GrantFiled: May 12, 2009Date of Patent: August 18, 2015Assignee: DATALOGIC SCANNING GROUP S.R.L.Inventors: Pier Giorgio Peruzzi, Fabio Maria Albanese, Antonio Picciano

Patent number: 9078049Abstract: Program code in a Web page hosted by a server and/or in server side code executed by the server is specially configured so that a modified media file whose source is embedded in the Web page and which is streamed by the server is properly playable only in browsers of media devices accessing the Web page. Thus, if a copy of the modified media file is downloaded to the media device or otherwise procured, the user of the media device is unable to properly play the downloaded copy by using a conventional media player. Further, if the downloaded copy is shared on a file sharing network, users of the file sharing network that download copies from the media device are also unable to properly play their downloaded copies by using conventional media players.Type: GrantFiled: September 13, 2010Date of Patent: July 7, 2015Assignee: ROVI TECHNOLOGIES CORPORATIONInventor: Timothy Neil Bland

Patent number: 9021126Abstract: A data processing apparatus includes multiple processing means that are connected in a ring shape via corresponding communication means respectively. Each communication means includes a reception means for receiving data from a previous communication means, and a transmission means for transmitting data to a next communication means. Connection information is assigned to each of the reception means and the transmission means. The communication means, when receiving a packet that has same connection information as one assigned to its reception means, causes the corresponding processing means to perform data processing on the packet, sets the connection information assigned to its transmission means to the packet, and transmits the packet to the next communication means, and when receiving a packet that has connection information that is not same as one assigned to its reception means, transmits the packet to the next communication means without changing the connection information of the packet.Type: GrantFiled: January 15, 2010Date of Patent: April 28, 2015Assignee: Canon Kabushiki KaishaInventor: Hisashi Ishikawa

Patent number: 9007983Abstract: Channel characterization and training within multiple user, multiple access, and/or MIMO wireless communications. Within such communication systems, there can be a number of devices (e.g., STAs) that communicate with a single device (e.g., AP). A multi-cast sounding frame may be transmitted from a transmitting device to a number of receiving devices. Appropriate scheduling or ordering of feedback signals from some or all of the receiving devices may be performed explicitly (e.g., sounding frame sent from the transmitting device to a receiving device) or implicitly (e.g., control information sent from the transmitting device to the receiving device, sounding frame sent to the transmitting device from the receiving device). Such characterization and training is with respect to a channel or path in which data will subsequently follow. Such characterization and training can be performed in accordance with group membership (e.g., with respect to only some of the receiving devices).Type: GrantFiled: June 28, 2013Date of Patent: April 14, 2015Assignee: Broadcom CorporationInventors: Matthew James Fischer, Joonsuk Kim, Peiman Amini, Joseph Paul Lauer, Vinko Erceg

Patent number: 8995918Abstract: A broadband device (105) can detect a proximate narrowband transmission (152) from a narrowband communication device (145). The narrowband transmission (152) can be in close enough proximity (155) to at least one bearer channel of the broadband device (105) to result in interference on the narrowband reception (152) when the broadband device (105) is transmitting and the narrowband communication device (145) is concurrently receiving. Responsive to the detecting, the broadband device (105) can gate a broadband transmission (142) to ensure the broadband transmission (142) does not interfere with the proximate narrowband reception (152). In absence of detecting the narrowband transmission (152), the broadband transmission (142) from the broadband device (105) would not be gated.Type: GrantFiled: November 14, 2011Date of Patent: March 31, 2015Assignee: Motorola Solutions, Inc.Inventors: Gino A.

Patent number: 8977308Abstract: Apparatuses and methodologies are described that mitigate signal pollution in a wireless communication system. According to one aspect, user devices can request signals for use in access point selection. Access points can be selected based upon the received strength of their signals. In one aspect, access points can delay the transmission of signals based upon the strength of the received request. In addition, if sufficient access points respond during the delay, an access point can refrain from transmitting signals in response to signal requests, further reducing signal pollution.Type: GrantFiled: February 22, 2006Date of Patent: March 10, 2015Assignee: QUALCOMM IncorporatedInventor: David Jonathan Julian
