  • Patent number: 9264176
    Abstract: The system and method of the present invention uses a plurality of carriers by assigning user terminals to the plurality of carriers so that a minimum grade of service is met and so that throughput is maximized. Each serviced user terminal reports the channel quality of each of a plurality of carriers to a servicing base station(s). The reported channel qualities are then converted to maximum supported data rates for each of the user terminals and each of the carriers. These data rates are then used to allocate data service levels and data rates for each of the user terminals so that a minimum grade of service is met for each of the user terminals. Forward link transmissions, e.g., frames/data packets carried on forward channels (F-CHs), are then constructed and transmitted to meet the allocations.

  • Patent number: 8781317
    Abstract: Phase nonlinearities of an optical communications system are monitored by generating a test signal which includes a predetermined property that is uniquely associated with at least one phase nonlinearity of the optical communications system. The predetermined property of the test signal is then detected at a monitoring point of the optical communications system, and used to estimate the associated phase nonlinearity.

  • Patent number: 7596123
    Abstract: A frame structure that is ordinarily optimized for providing variable high data rates also includes the flexibility to efficiently carry lower data rate, lower latency frames using sub-framing. Superframes, each comprised of a predetermined number of frames, carry voice and data communications at one or more variable data rates. The size of a superframe is limited, such as by the delay tolerance for voice transmission, typically 20 ms. Each voice customer is allotted one or more frames or portions of frames within the superframe, called sub-frames, as is needed to deliver the lower data rate, low latency voice communication. The allocation for the voice customers is not fixed, but varies as the data rate varies over time. Any bits in a frame that are not needed to carry voice communication are assigned to carry data having compatible data rate requirements. Additionally, the sub-framing concept may be extended to include ATM cells.

  • Patent number: 7484120
    Abstract: A base station, mobile station, and/or other terminal device includes physical layer (layer 1) protocol and link layer (layer 2) protocol that both include automatic retransmission request (ARQ) operations. The physical layer and link layer include enhancements that interact with one another to cause the link layer to inhibit ARQ operations while error recovery operations are pending at the physical layer. A transmitter packages link layer packet data units into physical layer frames and transmits the physical layer frames. A receiver responds to indicate either successful or unsuccessful transmission. The transmitting physical layer waits for the response and initiates error recovery operations when required. The receiving link layer, when it detects lost data packets, inhibits its ARQ operations to allow physical layer error recovery operations to complete.

  • Patent number: 7463600
    Abstract: A frame structure that is optimized for providing variable high data rates. Superframes, each comprised of a predetermined number of frames, carry data communications at one or more variable data rates. Each data customer is allotted one or more frames or portions of frames within the superframe, called sub-frames, as is needed to deliver the data communication. The allocation for the data customers is not fixed, but varies as the data rate varies over time, and also to meet the needs of the data customers. Each high speed data frame includes a self-indication of the contents of the high speed data frame. This self-indication identifies one or more data users serviced by the high speed data frame and the data rate of the data contained in the high speed data frame. Each high speed data frame may service multiple user terminals, with the high speed data frame subdivided into two or more subframes.
