    摘要: Systems and methods for designing, using, and/or implementing hybrid communication networks are described. In various embodiments, these systems and methods may be applicable to power line communications (PLC). For example, one or more of the techniques disclosed herein may include methods to coordinate medium-to-low voltage (MV-LV) and low-to-low voltage (LV-LV) PLC networks when the MV-LV network operates in a frequency subband mode and the LV-LV network operates in wideband mode (i.e., hybrid communications). In some cases, MV routers and LV routers may have different profiles. For instance, MV-LV communications may be performed using MAC superframe structures, and first-level LV to lower-level LV communications may take place using a beacon mode. Lower layer LV nodes may communicate using non-beacon modes. Also, initial scanning procedures may encourage first-to-second -level LV device communications rather than MV-to-first-level LV connections.

    摘要: A system and method for protecting a wireless device including co-located network transceivers from uplink starvation are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver respectively configured for communication via a first wireless network and a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic determines a duration of a pending transmission via the first transceiver, and determines a predicted start time of a predicted transmission via the second transceiver. Based on the duration and the predicted start time, the logic transmits a notification signal indicating that a receiving device should refrain from transmitting on the first network for a reserved time ending after the pending transmission starts. The pending transmission starts following completion of the predicted transmission.

    摘要: A method for interference management in a self optimizing network includes determining quality of service constraints for a call; mapping the quality of service constraints for the call to a target signal-to-interference noise ratio; and transmitting power control signals for the call based on the target signal-to-interference noise ratio. The utility function can be optimized for each class of calls over the network so as to maximize the total number of calls that can be handled.

    摘要: A system for synchronizing sender sliding windows and receiver sliding windows employed in wireless packet communication is provided. The sender sliding window buffers outgoing packets to be sent to a receiver that employs a receiver sliding window to buffer incoming packets. A sender window manager manages the sender sliding window through positive acknowledgement, negative acknowledgement and/or timeout processing to facilitate synchronizing the sender sliding window with the receiver sliding window without employing synchronization messages or master/slave control. Similarly, a receiver window manager manages the receiver sliding window through sequence number analysis to facilitate synchronizing the receiver sliding window with the sender sliding window without employing synchronization messages or master/slave control.

    摘要: A resynchronization method for use in a data communication system having a first device configured to transmit data at a symbol rate to a second device. The second device includes a Reed Solomon (RS) decoder having a RS lock indicator and a Moving Picture Experts Group (MPEG) Protocol Interface (MPI) having a MPI lock indicator, wherein the RS and the MPI lock indicators are monitored. Four different states, defined by the values of the RS and MPI lock indicators, determine whether the data communication system will wait for the RS decoder and the MPI hardware block to resynchronize, whether an intermediate-subset of the channel acquisition algorithm is performed or whether the entire channel acquisition algorithm is performed. The method for resynchronization described herein recovers synchronization within a predetermined time without the layers above the physical link layer having knowledge.
