Patent number: 9621474Abstract: A relay wireless communication device is implemented to perform buffer management and coordination with a source wireless communication device. A relay wireless communication device (generally, a relay) informs a source wireless communication device (source) of the status of memory therein to store messages intended for a destination wireless communication device (destination). For example, the source transmits information to the relay, which buffers information before forwarding it on to the destination. This buffering may be a function of the source having additional information intended for the relay and/or destination. The relay performs appropriate signaling, such as suspend transmission requests and resume transmission requests, to inform other devices in the system of its memory storage status (e.g., such as when having an actual or anticipated overflow).Type: GrantFiled: October 5, 2015Date of Patent: April 11, 2017Assignee: Avago Technologies General IP (Singapore) Pte. LtdInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Patent number: 9379837Abstract: A wireless communication device includes communication interface configured to receive and transmit signals and a processor configured to generate and process such signals. The communication interface of the wireless communication device is configured to receive a first signal from a first other wireless communication device, and the processor of the wireless communication device is configured to process the first signal to determine one or more concurrent transmission parameters. The processor of the wireless communication device is configured to generate the second signal based on the one or more concurrent transmission parameters and direct the communication interface to transmit the second signal to a second other wireless communication device during receipt of the first signal from the first other wireless communication device. The wireless communication device may be configured to make such concurrent transmissions based on one or more considerations such as the power level of the first signal.Type: GrantFiled: February 27, 2014Date of Patent: June 28, 2016Assignee: BROADCOM CORPORATIONInventors: Nihar Jindal, Yong Liu, Matthew James Fischer, Ron Porat, Chiu Ngok Eric Wong, Vinko Erceg

Patent number: 9350438Abstract: A relay receives a frame from a source, and based on state of a relayed frame bit within the frame, the relay selects an operational mode: implicit acknowledgement mode, first explicit acknowledgement mode, or second explicit acknowledgement mode. The relay sets the relayed frame bit in subsequent transmissions to indicate transmission opportunity (TXOP) control of the communication medium (e.g., whether under control of the relay or the source). The source may receive acknowledgement of the relay's successful receipt of the frame implicitly via the relay transmitting a relayed frame to the destination. Alternatively, the source may receive acknowledgement of the relay's successful receipt of the frame explicitly in a response frame from the relay. State of a more data bit in the frame receive from the source may indicate the source has one or more additional frames intended for the destination.Type: GrantFiled: July 31, 2015Date of Patent: May 24, 2016Assignee: Broadcom CorporationInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Publication number: 20160029380Abstract: A signaling protocol allows for speed frame exchange between different wireless communication devices within single user, multiple user, multiple access, and/or MIMO wireless communication system. A listening wireless communication device analyzes state of speed frame indicator bits within frames transmitted from a first other wireless communication device to determine the entire radio frame exchanges between that first other wireless communication device and a second other wireless communication device. The second other wireless communication device may be a hidden node relative to the listening wireless communication device such that all or less than all transmissions from the hidden node are received by the listening device. The listening wireless communication device determines the status of the communication medium (e.g.Type: ApplicationFiled: October 5, 2015Publication date: January 28, 2016Applicant: BROADCOM CORPORATIONInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Publication number: 20160021611Abstract: Session recovery after network coordinator or AP restart for single user, multiple user, multiple access, and/or MIMO wireless communications. Restart or reset of a network coordinator (e.g., an access point (AP) or other network coordinator type device) may occur for various reasons (e.g., a power cycle or power failure, inadequate failover protection, scheduled or planned power outages such as for including network maintenance, software upgrades, etc.). Upon determination of network coordinator restarted or reset, a singular bit within a communication from the network coordinator indicates synchronization or not of the its timing synchronization function (TSF) (e.g., with other devices in the communication system, such as wireless stations (STAs), smart meter stations (SMSTAs), etc.). A given device (e.g., STA, SMSTA, etc.) can provide its current TSF to the network coordinator so that it can resynchronize, re-establish its scheduled for wake times of those devices (e.g., target wake times (TWTs)), etc.Type: ApplicationFiled: May 27, 2015Publication date: January 21, 2016Applicant: BROADCOM CORPORATIONInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Publication number: 20150373620Abstract: A relay wireless communication device is discovered using probe request. A source device that intends to transmit one or more frames to a destination device transmits the probe request to request a probe response from one or more potential relay devices. A relay device transmits a probe response to the source device when the relay device may operate to forward the one or more frames from the source device to the destination device. The relay device employs one or more considerations to determine its eligibility to serve as relay for the source and destination devices. The source device selects one of the potential relay devices based on their provided probe responses. The source device may select an optimal relay device based upon two or more received probe responses.Type: ApplicationFiled: August 31, 2015Publication date: December 24, 2015Applicant: BROADCOM CORPORATIONInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Patent number: 9203755Abstract: A flow of packets sent from a server device over a TCP network to at least one endpoint device is identified, the endpoint device accessing the TCP network over a wireless access network. A message is identified from the endpoint device to the server device communicating an error condition relating to at least one packet in the flow. At least one processing device is used to predict that the error condition is based, at least in part, on a non-congestion-related condition within the wireless access network. The message is filtered to exclude communication of the error condition to the server based on the prediction that the error condition is based, at least in part, on a non-congestion-related condition within the wireless access network. In some aspects, the message can include a TCP duplicate acknowledgement (“DUP ACK”) message.Type: GrantFiled: September 27, 2011Date of Patent: December 1, 2015Assignee: CISCO TECHNOLOGY, INC.Inventors: Chiu Ngok Eric Wong, Jayaraman R.

Publication number: 20140362840Abstract: Coordination and synchronization is performed between two or more wireless network managers (e.g., access points (APs)). A first wireless network manager supports first communications with first other wireless communication devices, and a second wireless network manager supports second communications with those first and/or second other wirelessly case devices. The first and second wireless network managers also support communications with one another to coordinate the first and second communications supported with the first and/or second other wireless communication devices. Examples of coordination include selection of which other wireless communication devices are serviced or in communication with which of the first and second wireless network managers, selection of operational parameters (e.g., modulation coding set (MCS), beamforming, frequency band assignment, channel assignment, scheduling information, transmit power, etc.Type: ApplicationFiled: June 5, 2014Publication date: December 11, 2014Applicant: BROADCOM CORPORATIONInventors: Chiu Ngok Eric Wong, Ron Porat, Nihar Jindal, Matthew James Fischer, Vinko Erceg
