Patent number: 9143585Abstract: Data packets of multiple different protocols are transmitted over a broadband wireless air interface between network stations subscribing to the broadband wireless access service. A first network station receives data packets of different network protocols in an upper layer for transmission to a second station over the wireless air interface. The different protocol data packets are processed in the upper layer to look up a destination address and class of service, and are transmitted to a single generic packet convergence sublayer along with an identification tag indicating the destination address and class of service. The generic packet convergence sublayer maps the identification tag to a single connection ID (CID) of a second station of the broadband wireless access service, without having to carry out any packet inspection.Type: GrantFiled: July 7, 2006Date of Patent: September 22, 2015Assignee: Wi-LAN Inc.Inventors: Yair Bourlas, Lei Wang, Brian D.

Patent number: 8861437Abstract: For an example embodiment, a method for a communication device operating in a synchronous communication system is described. The method includes performing a listen-before-talk (LBT) procedure prior to the start of a downlink subframe of a synchronous frame and determining if a transmission from another communication device of another communication system is detected during the LBT procedure. In the case that a transmission is detected during the LBT procedure, the communication device refrains from transmitting during the downlink subframe. In the case that a transmission is not detected during the LBT procedure, the communication device transmits during the downlink subframe.Type: GrantFiled: June 21, 2011Date of Patent: October 14, 2014Assignee: Wi-LAN, Inc.Inventors: Kenneth L.

Patent number: 8774229Abstract: A wireless broadcast system that collects content for distribution over a wireless communication network. The content stream is encapsulated into a stream of transport packets for broadcast over the wireless communication link. The stream of transport packets are simultaneously broadcast as part of an identical signal from a plurality of synchronized transmitters in a single frequency network. A receiver acquires the broadcast signal and synchronizes to the signal. Once the receiver is synchronized to one of the transmitters in the single frequency network, the receiver can receive signals from any, or multiple, of the transmitters in the network without re-synchronizing.Type: GrantFiled: January 12, 2007Date of Patent: July 8, 2014Assignee: WI-LAN, Inc.Inventors: Dennis P.

Patent number: 8509073Abstract: An error management system and process can be used to identify an erroneous data packet in a data stream. In response to identifying the erroneous data packet, a subsequent valid data packet is located in the data stream. In one embodiment, a plurality of candidate locations of header checksum windows are searched and checked for a valid checksum. Multiple integrity checks of multiple header checksums can be used to reduce the probability of a false positive integrity check. In another embodiment, one or more information data fields can used for determining packet integrity by determining if the fields contain valid information bits.Type: GrantFiled: March 29, 2011Date of Patent: August 13, 2013Assignee: Wi-Lan, Inc.Inventors: Yair Bourlas, Brian D.

Patent number: 7944919Abstract: A wireless broadcast system that collects content for distribution over a wireless communication network. Multiple content streams are received and interleaved into an aggregate content stream. The aggregate content stream is encapsulated into a stream of transport packets that are ruggedized for broadcast over the wireless communication link. One connection identification is associated with the entire aggregate content stream. The aggregate content stream is packetized into multiple service data units. An identical signal that includes the service data units and one connection identifier is broadcast by multiple synchronized transmitters in a single frequency network. The content can include multimedia data, such as audio/video data, movies, game, audio broadcasts, television network programs, or other types of multimedia content.Type: GrantFiled: January 12, 2007Date of Patent: May 17, 2011Assignee: Wi-Lan, Inc.Inventors: Dennis P.

Publication number: 20110096664Abstract: A method of flow control implemented by a system disposed to execute a protocol stack and an application is disclosed herein. The method includes configuring the system to operate in a push mode pursuant to which the protocol stack initiates the forwarding, to the application, of a first sequence of data packets received by the protocol stack. The system may also be configured to operate in a pull mode pursuant to which the application initiates the forwarding, to the application, of a second sequence of data packets received by the protocol stack. In a particular implementation the system may be configured to transition from the push mode to the pull mode, or vice-versa, in response to receipt at the protocol stack of a data packet bearing a specified sequence number.Type: ApplicationFiled: September 20, 2010Publication date: April 28, 2011Inventors: Brian D.

Patent number: 7912057Abstract: A wireless broadcast system includes receiving a data a stream by a convergence module. The convergence module partitions and encapsulates the transport packets into MAC protocol data units such that a size dimension of the encapsulated transport packets matches a size dimension of the MAC protocol data units. The MAC protocol data units are then provided to a transmitter that is synchronized to a plurality of transmitters in a single frequency network so that each transmitter in the network broadcast an identical signal that includes the MAC protocol data unit.Type: GrantFiled: January 12, 2007Date of Patent: March 22, 2011Assignee: Wi-LAN Inc.Inventors: Brian D.
