  • Patent number: 9049702
    Abstract: 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.

  • Patent number: 8982846
    Abstract: 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.

  • Patent number: 8634352
    Abstract: 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.

  • Patent number: 8130736
    Abstract: A method and system for facilitating channel measurements in a communication network is disclosed. The method includes contending for a control channel to reserve a logical subchannel of a data channel. The control channel operates in a first frequency band and the data channel operates in a second frequency band. Further, the method includes sending an announce message on the control channel for announcing a reservation at a particular time period of the logical subchannel of the data channel when the contention for the control channel is successful, sending a channel sense message on the logical subchannel of the data channel at the particular time period to facilitate at least one other node to perform channel measurements based on the channel sense message, and monitoring the data channel and performing channel measurements based on at least one other channel sense message received from the at least one other node.

  • Patent number: 8068454
    Abstract: 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.

  • Patent number: 7894371
    Abstract: A system and method of resource allocation within a communication system is provided. 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.
