Patent number: 9860753Abstract: A method and apparatus for allocating bandwidth in a broadband wireless communication system is disclosed. One embodiment uses a self-correcting bandwidth request/grant protocol. The self-correcting bandwidth request/grant protocol utilizes a combination of incremental and aggregate bandwidth requests. CPEs primarily transmit incremental bandwidth requests to their associated base stations, followed by periodic transmissions of aggregate bandwidth requests. The use of periodic aggregate bandwidth requests (that express the current state of their respective connection queues) allows the bandwidth allocation method and apparatus to be “self-correcting”. Another embodiment utilizes an abridged bandwidth request/grant protocol to allocate bandwidth. The abridged bandwidth request/grant protocol system utilizes padding packets to request a reduction in bandwidth allocation to a CPE. A base station modem alerts a base station CPU when the BS modem receives a padding packet from a CPE.Type: GrantFiled: March 20, 2017Date of Patent: January 2, 2018Assignee: Wi-LAN Inc.Inventors: Ofer Zimmerman, Kenneth L.

Publication number: 20170332351Abstract: A multicast broadcast service controller is disclosed. The MBSC processes multicast broadcast data streams for transmission to access service network gateways or base stations. The MBSC includes a MBSC core processor for establishing time synchronization information used by the access service network gateways or base stations to synchronously transmit data streams. The MBSC core processor selects streams for transmission in a time diversity interval (TDI) and builds multicast broadcast (MBS) region content based on the selected streams and configuration information. The MBS region content includes timing synchronization information, resource information and MBS region content location information. A MBS region distribution module (MRD) transmits the MBS region content to the access service network gateways or base stations.Type: ApplicationFiled: August 1, 2017Publication date: November 16, 2017Applicant: Wi-LAN Inc.Inventors: Yoav Nebat, Sina Zahedi, Dennis Connors

Patent number: 9814026Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.Type: GrantFiled: July 22, 2014Date of Patent: November 7, 2017Assignee: Wi-LAN Inc.Inventors: Kenneth L.

Patent number: 9775002Abstract: Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.Type: GrantFiled: July 20, 2015Date of Patent: September 26, 2017Assignee: WI-LAN INC.Inventors: Srikanth Gummadi, Ron Porat, Todd R.
