20110141965 | NETWORK DISCOVERY IN WIRELESS COMMUNICATION SYSTEMS - Apparatuses may stay synchronized with a network via a beacon signal transmitted at a set interval. Communication-related activities may be planned around instances when beacon signals are expected, which may also be known as a target beacon transmission time (TBTT). Scanning opportunities, which are periods of time during which apparatuses may perform passive scanning, may be planned based on an interfere multiple of a network beacon signal interval. Apparatuses may, upon realizing a scanning opportunity, opt either to utilize the scanning opportunity or to participate in network beaconing. In example scenarios where apparatuses opt to utilize scanning opportunities, apparatuses may prepare a network information message and then enter a passive scanning mode. Apparatuses may remain in the passive scanning mode for the duration of the scanning opportunity, reacting when messages are received from devices outside of the network by transmitting the network information message. | 06-16-2011 |
20110141966 | DATA-RELATED TASK SUPPORT IN WIRELESS COMMUNICATION SYSTEMS - Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT). While some networked apparatuses are active during every TBTT, other apparatuses may operate using a diluted beacon period that is an integer multiple of the network beacon signal interval. Diluted beacon intervals may initiate periods of time during which apparatuses may become “aware” of other apparatuses. Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities. | 06-16-2011 |
20110142028 | SYNCHRONIZATION VIA ADDITIONAL BEACON TRANSMISSION - Apparatuses may stay synchronized with a wireless network utilizing a diluted beacon interval that is an integer multiple of a network beacon period signal being transmitted at a set interval. Diluted beacon intervals may reduce communication burden, but may also cause periods of inactivity that allow apparatuses to become unsynchronized with the network. Apparatuses may be active in the network during an awake window wherein a beacon may be transmitted. A set time may also be set during the awake window may delineate a period of time after which any beacon signal received from another apparatus is deemed to be late. Receiving late beacon signals in the apparatus may trigger the transmission of additional beacon signals to help the other apparatuses that transmitted late beacons become resynchronized with the network. | 06-16-2011 |
20110142029 | NETWORKING IN WIRELESS COMMUNICATION SYSTEMS - A system where apparatuses may stay synchronized with a network utilizing a reduced beacon period based on an integer multiple of a standard beacon period that is established for the network. The reduced beacon periods may initiate scanning opportunities, which are periods of time during which apparatuses may passively scan for beacon messages broadcast from other apparatuses, which upon receipt in a scanning apparatus may trigger the transmission of network information messages. Network information messages may comprise connectivity information that would be usable by outside apparatuses to determine whether participation in the network described in the network information message (e.g., another network) is desired. If the apparatus desires to interact with apparatuses in the other network, then further decisions may be made with respect to how communication between these entities should be established. | 06-16-2011 |

The server may return information to the apparatus via the Internet informing the apparatus of other proximately-located apparatuses. The apparatus may utilize this information to communicate with the proximate apparatuses in order to coordinate collaborative operations. | 07-21-2011 |
20110216753 | CROSS LAYER SERVICE DISCOVERY FOR WIRELESS NETWORKS - Service discovery for services on a wireless network is presented.

Then in a message, that is available to entities not joined to the network, is placed information about the services and also at least one of location information about the offering apparatus and link metric information about a network path to the offering apparatus. A discovering apparatus reads one or more transmitted messages (from different apparatuses in the same network in different networks), sees the service it wants is available through both, compares the different locations and/or the different link metrics, and based on the comparing chooses which network to join, or with which apparatus on the single network to create a peer link | 09-08-2011 |
20110222408 | SIMULTANEOUS TRANSMISSIONS DURING A TRANSMISSION OPPORTUNITY - Method, apparatus, and computer program product embodiments are disclosed to enhance capacity of a wireless communication network through spatial reuse of the shared communication medium, using an autonomous parallel operation without central coordination and header frames.

In example embodiments of the invention, an arrangement may be made between device pairs (each pair comprising a transmitter device and a receiver device) to allow selected pairs to communicate at a same time. The example signaling method defines example signaling for setting up simultaneous transmitter/receiver pairs in a network and operating the transmitter/receiver pairs in simultaneous transmission. If a device in a setup pair detects some other transmission than that is not allowed by one of its device pair arrangements, the device ceases its transmission. | 09-15-2011 |

There are two graduated stages to the analysis. In an example light analysis stage, an analysis of the allocation of resources is limited to neighboring networks within the same network allocation group as the requesting network's. In a more extensive analysis stage, all of the neighboring networks are analyzed. In this manner, a more complete resource reallocation may be achieved. | 12-15-2011 |
