A method and apparatus for distributing live video to multiple client devices is provided herein. In particular, a router is provided that acts on behalf of all client devices in its network. The router serves multiple groups of client devices with each group being formed by client devices having similar bandwidth requirements. The router then requests and receives video chunks from a network. The router then redistributes the video chunks to the multiple client devices using a multicast transmission. In particular, to minimize the demands on the core network, the router sets up a separate multicast to each group. Live video, of the appropriate quality is then multicast to each group.

Method and apparatus for distributing video

A base station allocates resources for peer-to-peer communications by creating or updating peer sets from measured performance information received from one or more stations. Based on current resource assignments in each timeslot and based on the peer sets, the base station determines excluded timeslots and preferred timeslots. The base station then marks potential resources in a portion of a resource allocation map. One of the potential resources is allocated for peer-to-peer communication between a transmitter station and one or more receiver stations.

Method and apparatus for scheduling various types of peer-to-peer communication links

Systems, methods and apparatus are provided for scheduling resources in Orthogonal Frequency-Division Multiple Access (OFDMA) communication networks for 'direct link' or peer-to-peer communications among stations operating therein so that OFDMA resources can be allocated to a transmitter station for a peer-to-peer communication session with a receiver station such that near-far issues caused by peer-to-peer communication are reduced/avoided. The disclosed technologies can prevent peer-to-peer communication links using different sub-channels within the same time slot from creating near-far issues for other receiver stations that are within communication range.

A subscriber station (SS) utilizes uplink resources that have been assigned to it for communicating with an infrastructure station to exchange data with a neighboring SS while maintaining its link to the infrastructure station. This is accomplished by the SS receiving an uplink allocation from the infrastructure station, transmitting a subscriber-to-infrastructure station header and trailer to the infrastructure station using the modulation and coding scheme (MCS) assigned by the infrastructure station and also transmitting a subscriber-to-subscriber (S2S) message payload, optionally using a second MCS level appropriate for the link between itself and the receiving SS. The subscriber to infrastructure station message is composed so that it occupies the first m codewords and contains a header that describes the length of the subscriber to infrastructure station message. The subscriber to infrastructure station message, then, is followed by the S2S message, composed to occupy the remaining symbols of the allocation.

Some embodiments are directed to a method and apparatus for performing resource negotiation in a station implementing a direct communication link with at least one other station on an Orthogonal Frequency-Division Multiple Access (OFDMA) data channel. The station scans sub-channels on the data channel for base headers included in predefined position in transmissions sent on the sub-channel. The station then decodes a base header in at least one selected sub-channel to obtain parameters of a channel reservation. The obtained parameters are stored in a channel utilization table. The station selects a resource on the data channel in at least one of time or frequency that the station has observed to be free using information from the channel utilization table. The station then begins a resource negotiation process about the selected resource.

A method is provided which enables the connection of nodes out of communication range while minimizing the energy consumption in standby nodes. Specifically, the present invention provides a method to control the wake up rate of standby nodes in a multi-hop communication system. An access point collects, processes, and refines statistical information regarding one or more system parameters; determines a wake up rate based on the statistical information and one or more historical information; and transmits the wake up rate to nodes in its coverage area. A node receives the wake up rate; and periodically changes from a sleep state to a wake up state at the wake up rate to support routing functions for providing multi-hop communication to the one or more access points.

A method and apparatus for operation of a node within a mobile ad hoc cognitive radio network is provided. The method includes sensing at least one assigned communications channel. Sensing at least one assigned communications channel includes measuring a value of at least one parameter corresponding to the communications channel. The method further includes comparing the measured value of the at least one parameter with a set of stored values of the at least one parameter to determine a change in the measured values. Finally a sleep mode of the node is activated for a time period, wherein the time period is determined using the change in the measured values.

A method of operation of a node for multi-band communication routing within a wireless communication system comprises communicating a communication session on a default route within an identified quality of service objective on a first frequency band; broadcasting, on a second frequency band, one or more route discovery messages at each of a plurality of sets of transmission variables; storing one or more alternate route table entries in a route table, wherein each of the one or more alternate route table entries are indexed by each of the plurality of sets of transmission variables that are at least within the quality of service objective; selecting a stored alternate route that is at least within the quality of service objective of the communication session on the second frequency band; and switching the communication session to operate using the transmission variables related to the selected alternate route.

A method and apparatus for quieting multiple channels is provided herein. During operation, transmission activity on each channel is analyzed and a best band is identified. Once the band is chosen, a wideband transmitter is utilized to transmit simultaneous reservation messages on consecutive channels simultaneously. Because a wideband transmitter is used to transmit simultaneous reservation messages on multiple consecutive channels, the above procedure quickly quiets multiple channels while minimizing the reservation duration of all channels as a result of quieting the channels.

Method to quite consecutive narrow band channels

This information can comprise, at least in part, a biometric template as pertains to a user of the two-way communications apparatus and a privacy policy as pertains to further dissemination of the biometric template.

A method for enabling mobile coverage extension and peer-to-peer communications in an ad hoc network is provided. The method includes communicating at least one message among the plurality of nodes, wherein the at least one message comprises: an ad hoc zone, wherein the ad hoc zone comprises at least one channel selected from a group of channels comprising: at least one synchronization channel for synchronizing out of coverage nodes, at least one access channel for peer-to-peer communications, and at least one ad hoc relay data/traffic channel for exchanging data during data sessions between one or more nodes.

A communication system comprises a plurality of nodes operating in a first architecture network mode, wherein at least a portion of the plurality of nodes are reconfigured to operate in a second architecture network mode in response to a change in one or more network performance requirements. When the plurality of nodes are operating in a distributed architecture network mode, at least a portion of the plurality of nodes are reconfigured to operate in a clustered architecture network mode in response to an increase in one or more network performance requirements. When the plurality of nodes are operating in a clustered architecture network mode, at least a portion of the plurality of nodes are reconfigured to operate in a distributed architecture network mode in response to a decrease in one or more network performance requirements.
