摘要： An apparatus and methods are provided for opportunistically conducting data communications on multiple wireless channels. In these methods, a device is engaged in data communications with a second device and receives a conflicting communication demand requiring action on one or more channels other than the data-communication channel (e.g., to conduct a channel scan, to issue or receive a beacon). The device arranges a schedule of channel switches to satisfy the communication demand and advises the second device of the schedule, and may explicitly invite the second device to implement the schedule. To the extent the second device does so, the data communications continue on the other channels. The devices may be participating in a synchronized peer-to-peer communication environment that requires their attendance on the data-communication channel and that is not associated with the other channels.

摘要： A system, apparatus and method for selecting one or more synchronization stations, or masters, in a peer-to-peer communication environment. Synchronization (or sync) stations broadcast periodic synchronization frames to advertise future availability windows, during which devices rendezvous for discovery and communication. Devices that can act as sync stations advertise preference values, which indicate their preference or suitability for the role. All devices execute the same algorithm to sort the preference values and identify a root sync station and any number of branch sync stations; leaf devices synchronize with the root or a branch sync station. This passive synchronization scheme allows individual devices to conserve power, because they need not actively discover other devices and services, and can power off their radios for periods of time without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexist with other device demands, such as Bluetooth® operations and infrastructure-based communications.

摘要： A system, apparatus and method for synchronizing devices in a peer-to-peer communication environment. Devices select a master to facilitate their synchronization, and rendezvous according to a schedule of availability windows broadcast by the master. Devices may attend some or all of the availability windows, during which they may send and receive unicast and/or multicast messages. Individual devices conserve power by being automatically synchronized instead of having to individually discover other devices and services, and can power off their radios without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexists with other device demands, such as Bluetooth® operations, infrastructure-based communications and so on.

摘要： A system and method for peer-to-peer communications is disclosed. A first wireless device receives a message from a second wireless device identifying communication requirements of a point-to-point communication involving the second wireless device. The first wireless device determines whether the second wireless device's communication requirements can be satisfied based on communication resources already committed for other communications. When the communication requirements of the second wireless device can be satisfied, the first wireless device generates a time sharing schedule to be used by the first and second wireless devices based on the already-committed communication requirements and the second device's communication requirements. The time sharing schedule may include a first portion for broadcast communication among a group of devices to which the first and second wireless devices belong, and a second portion for the point-to-point communications of the second wireless devices.

摘要： A system, apparatus and method for organizing devices in a peer-to-peer communication environment. A number of devices synchronize among themselves and select masters (or synchronization stations) to organize the devices into a hierarchy. Master devices have associated preference values reflecting their preference or suitability to be a master device, and broadcast synchronization frames to keep devices synchronized. When multiple devices in one or more hierarchies execute a common application or service, they form a private group to exchange or share data (e.g., play a game, transfer a file). All devices in the hierarchy maintain and advertise a public or default identifier of the hierarchy, and all devices in the private group maintain and advertise a private identifier specific to the group. Members of the group synchronize under a top group master (or root sync station), which synchronizes with a master that is part of the hierarchy.

摘要： A system, apparatus, and method are provided for operating a peer-to-peer communication environment. The environment includes one or more clusters of peer devices, wherein devices in a single cluster are organized into a logical hierarchy under an anchor master (at the root of the hierarchy) and any number of synchronization masters; other devices are non-master devices. Synchronization parameters established by the anchor master and disseminated throughout the hierarchy enable the clusters' devices to rendezvous, discover peers and services, and communicate among themselves. The anchor master may adjust the synchronization parameters to avoid conflict with another hierarchy. Each device issues beacons (e.g., heartbeats, discovery beacons) that identify the number of devices synchronized with the reporting device, which allows the anchor master to calculate the total number of cluster members. Devices may also report details of a neighboring cluster (e.g., its synchronization parameters) via a beacon or some other communication.
