摘要:
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 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.
摘要:
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.

During operation, nodes that receive beacons from a different network will synchronize to the different network when a predetermined condition is met. Synchronization to the differing network will only take place if the node receiving the beacon from a different network does not have access to a fixed network coordinator and the predetermined condition is met. The predetermined condition may comprise such things as a Network ID for the different network being larger than the Network ID for the current network, or alternatively, the size of the different network being larger than a size of the current network.

摘要:
A method and apparatus for synchronizing a node (200) within an ad-hoc communication system (100) is described herein. During operation all nodes periodically broadcast a synchronization beacon for other nodes to utilize for synchronization when a coordinating access point (node) is unavailable. A particular node's synchronization beacon will have an associated “tier” number that is incremented from the tier number of the beacon used to synchronize the particular node. In the absence of an access point, a node that joins the ad-hoc communication system will listen for synchronization beacons transmitted by other nodes. If synchronization beacons are heard, the node will synchronize with a beacon having a lowest tier. The node will then broadcast its own beacon having its tier number incremented from the lowest tier beacon heard.

Disclosed are methods that associate “importance” information with chunks of a media presentation. An end-user device uses this information to intelligently manage resources when downloading or rendering the media presentation. An editor tags a chunk as important based on the contents of the chunk. The importance information includes a recommendation that this chunk be rendered at a higher-than-usual resolution and that the end-user device start downloading this chunk out of order. An advertiser recommends that an advertisement be rendered at a resolution high enough for the end user to view it appropriately. The importance information can include a recommended point at which to display the advertisement (e.g., between scenes in the media presentation). The end-user device can download advertisements before they are needed. Later, when the user requests a media presentation, an already downloaded advertisement is rendered while the initial chunks of the media presentation are downloaded.
