  • Patent number: 8848619
    Abstract: Interference that occurs during wireless communication may be managed by subframe time reuse. A method, apparatus amend medium of communication determines interfering subframe gating sequences. The transmission gating in a home access point is adjusted by determining a first gating sequence from a first unplanned access point. A second gating sequence is selected based on the first gating sequence, wherein the first and second gating sequences are non-interfering. Signals are transmitted according to the second gating sequence from a second unplanned access point to an associated access terminal.

  • Patent number: 8737313
    Abstract: A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations a wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

  • Patent number: 8274908
    Abstract: Apparatuses, methods, systems, and computer program products to process QoS packets of wireless traffic without explicit control negotiations are disclosed. An embodiment may comprise a mobile computing device with wireless communications capabilities. The mobile computing device may be a client that associates or connects with an access point or communicates another client device, such as a peripheral device with wireless capabilities. The mobile computing device may monitor wireless packet traffic being transmitted from the mobile computing device. For example, the mobile computing device may monitor the packets being transmitted from a video streaming application to the peripheral device, which may comprise an LCD monitor that has wireless communications capabilities. The mobile computing device may mark the packets of the video stream as QoS packets even though the video streaming application may not do so, and place the marked packets in a QoS queue for priority processing.

  • Patent number: 8228859
    Abstract: The present invention is intended to protect an industrial wireless communication method based on self-adaptive channel hopping within timeslot, which belongs to industrial wireless communication technology field. Aiming to solving existing problem that wireless devices can not correspondingly self-adaptive channel hopping according to environment changing, a method for making the two communication sides self-generate and execute channel switch when the preferred channel was interfered. The sender will monitor whether the channel is idle within SWTW before sending data through mechanisms such as CCA or non-persistent CSMA. If the channel is still busy till the SWTW times out, the sender will give up sending data and implement channel switching control command by considering this communications channel as interfered. If no packets were received till the RWTW time-outs, the receiver will thinks the communication channel was interfered and automatically implement channel switching control commands.

  • Patent number: 8213358
    Abstract: An embodiment of the current invention is directed to a method of reducing the latency associated with communicating data to a mobile device. It is determined that a threshold period of time has elapsed since a mobile device has communicated a location-determining message. A request for the mobile device to transition to a quick-paging recognition mode is sent to a mobile device configured to perform a process. The process includes: sending a response to the first request as a location-determining message; transitioning to a quick-page recognition mode; receiving an indication to receive a paging-channel message; acquiring the paging-channel message; and returning to the quick-page recognition mode.

  • Patent number: 8194536
    Abstract: A vehicle active network (12) communicatively couples devices (14-20) within a vehicle (10). Device operation is independent of the interface (22-28) of the device (14-20) with the active network (12). Additionally, the architecture of the active network (12) provides one or more levels of communication redundancy. The architecture provides for the total integration of vehicle systems and functions, and permits plug-and-play device integration and upgradeability.
