20100226297 | POWER MANAGEMENT IN WIRELESS COMMUNICATION SYSTEMS - Embodiments of the present invention are directed to the invocation of active states and power conservation states in accordance with the standard or diluted beacon periods defined in beacon frames.

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 |
