  • Patent number: 9313771
    Abstract: A method and device for allocating a channel in a decentralized trunked radio communication system enables efficient channel utilization. The method includes scanning at a first subscriber unit a plurality of channels to determine whether a call of interest to a first subscriber unit is active in the system (step 410). The plurality of channels is then scanned at the first subscriber unit to identify a first channel that is clear in the plurality of channels after determining that there is no call of interest to the first subscriber unit active in the system (step 415). The first subscriber unit is then tuned to the first channel that is clear (step 420).

  • Patent number: 9300540
    Abstract: A Shortest Path Bridging (SPB) network provides a multicast traceroute using network identifiers such as IP addresses for the source and destination (multicast group). The network identifiers, which are based on layer 3 (IP) designations of the traced multicast group, are mapped to a network identifier of the multicast group (corresponding to a layer 2, or MAC address) and an associated Virtual Local Area Network (VLAN) which is used to transport the packets belonging to the multicast flow. Therefore, an operator issuing the traceroute command need not be familiar with the layer 2 concepts of the network, but rather need only supply the layer 3 (IP address) designations of the concerned entities.

  • Patent number: 9258792
    Abstract: Methods and apparatuses are provided for reporting power headroom for a UE. At least one of power control information associated with a PUSCH transmission in a subframe and power control information associated with a PUCCH transmission in the subframe is received. One of a first power headroom information and a second power headroom information is conditionally generated. One of the first power headroom information and the second power headroom information is conditionally transmitted. If the UE transmits the PUSCH without the PUCCH in the subframe, the second power headroom information is generated by subtracting the transmit power for the PUSCH transmission and a transmit power for a PUCCH from the maximum transmit power of the UE in the subframe based on the power control information associated with the PUSCH transmission and power control information associated with the latest PUCCH transmission.

  • Patent number: 9253072
    Abstract: In the subject system for polarity detection, link initialization between a primary device and a secondary device may be performed in at least two stages, a half-duplex stage when only the primary device transmits initialization signals and any encoded handshaking signals may be set to false, and a full-duplex stage when both devices may transmit initialization signals. The secondary device may perform polarity detection during the half-duplex stage. If the secondary device determines that the polarities of the received signals are reversed, the secondary device may reverse the polarities of any signals subsequently received from, and transmitted to, the primary device. In this manner, the polarities can be corrected for both devices during the half-duplex stage by the secondary device. The secondary device may initiate the full-duplex link initialization stage, during which any handshaking signals may be exchanged, by transmitting signals to the primary device.

  • Patent number: 9185639
    Abstract: A system and method of assisting a radio in finding a network is presented. A method first detects existing nodes. A message is received on a slow communication link in a slow network from a new node. One or more existing nodes are found that may connect to new node with a fast communication link in a fast network. The fast network has a data rate that is faster than the slow network. A message is transmitted over the slow network to the new node to provide the new node possible existing nodes that are near it that it may connect to. Based on that message the new node establishes a fast communications link on the fast network between the new node and an existing node. The fast communications link can be a directional link.

  • Patent number: 9155011
    Abstract: A method for transmitting data in a wireless radio network having a multiplicity of base stations for wirelessly sending and receiving data, wherein the base stations are wirelessly networked such that each base station can communicate wirelessly with one or more adjacent base stations. Broadcast messages are transmitted between a mobile station for wirelessly sending and/or receiving data and the base stations and broadcast messages are also forwarded between the base stations. These broadcast messages do not have an associated explicit connection between two units in the radio network. Moreover, the mobile station which receives a broadcast message can process this message regardless of the base station from which it originates. This avoids so-called “hand offs,” which are used in the prior art to associate a mobile station with a new base station when the mobile station moves out of range of the earlier base station.

  • Patent number: 9094173
    Abstract: Systems and methodologies are described that facilitate recovering from error due to false detection of completion signals at an access terminal. An access terminal specific request signal can be sent to a target base station to initiate handoff or semi-connected state exit. A completion signal can be transferred in response to the access terminal specific request signal. To mitigate errors stemming from false detection of the completion signal at the access terminal, forward link and reverse link confirmation signals can be transferred to confirm successful handoff or connected state re-entry completion. For example, the access terminal can determine handoff or re-entry to be successful when a forward link confirmation signal is detected prior to expiration of a timer. Moreover, the forward link and reverse link confirmation signals can each include more CRC bits as compared to a number of CRC bits included in the completion signal.
