摘要： A method of operating in a network in which a plurality of stations communicate over a shared medium. The method comprises transmitting a group of bits from a transmitting station to a receiving station, wherein the group of bits comprises information bits and error checking bits, and communicating additional bits from the transmitting station to the receiving station without transmitting the additional bits. Communicating the additional bits comprises, at the transmitting station, deriving the error checking bits from the additional bits using an error checking process; and at the receiving station, using the same or a related error checking process to process candidate bits known to the receiving station, and comparing the output of the error checking process to the error checking bits received from the transmitting station to determine if the candidate bits correspond to the additional bits.

摘要： There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator is configurable to transmit a beacon at an interval based on a phase of a powerline cycle. The interval of the beacon can be substantially equal to two periods of the powerline cycle. The interval of the beacon includes a reserved region including a persistent allocation region and a non-persistent allocation region. The beacon also includes a broadcast message including a persistent schedule and a non-persistent schedule. The persistent schedule is valid for a current beacon period and a number of subsequent beacon periods as indicated by the beacon, while the non-persistent schedule is valid for a single beacon period. The persistent allocation region and the non-persistent allocation region are determined based on the persistent schedule and the non-persistent schedule, respectively.

摘要： There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator includes a system clock and a network timer and is configurable to transmit a number of network timer values. Each of the network timer values can be transmitted by the central coordinator in one of a number of beacons. Each of the other stations is configurable to utilize the network timer values and a corresponding number of local timer values to estimate a frequency error between the system clock and a local clock and an offset between the network timer and a local timer. Each of the other stations is further configurable to utilize the frequency error and the offset to synchronize the local timer to the network timer.

Each of the stations is configurable to generate one or more tone maps for communicating with each of the other stations in the powerline network. Each tone map includes a set of tones to be used on a communication link between two of the stations. Each tone map further includes a unique set of modulation methods for each tone. Each of the stations is further configurable to generate a default tone map for communicating with each of the other stations, where the default tone map is valid for all portions of a powerline cycle. Each of the stations is further configurable to monitor its bandwidth needs and to request additional bandwidth from the central coordinator.

摘要： A method for communicating among nodes in a network includes determining, by a transmitter, a first frequency band and at least a second frequency band to be used for communicating data packets, wherein a maximum allowable power spectral density in the first frequency band is greater than a maximum allowable power spectral density in the second frequency band. The method also includes adjusting power spectral density for a first group of frequencies in the first frequency band such that the adjusted power spectral density of the first group does not exceed the maximum allowable power spectral density of the first frequency band and a quantization noise introduced by the transmitter is less than a threshold value for a signal transmitted in the second frequency band. The method further includes modulating at least a portion of a data packet transmitted by the transmitter to at least a first receiver in accordance with the adjusted power spectral density.

摘要： Methods of operating in a network in which a plurality of stations communicate over a shared medium and contend for access during a priority resolution period. At least some of the stations use a first CSMA network protocol having certain characteristics (e.g., some transmissions have a format that includes a start of frame delimiter (SOF), a payload, and an end of frame delimiter (EOF), wherein the SOF and EOF each contain sufficient information to permit a station receiving only one of the SOF and EOF to determine the start of a priority resolution period). And at least some stations use a second network protocol capable of coexisting with the first protocol, so that stations may communicate using either the first or second protocol. The second protocol may have various characteristics configured to achieve coexistence with the first protocol (e.g., transmissions that have a format that includes an SOF but not an EOF).

摘要： A method of operating in a network in which a plurality of stations communicate over a shared medium (e.g., using a carrier sense multiple access (CSMA) service). The stations contend for access to the shared medium using a contention procedure that relies on a priority level, wherein transmissions with a lower priority level have a reduced chance of gaining access to the shared medium during a contention process. Selected stations are given the capability of temporarily promoting the priority level of transmissions they are attempting to make. The priority level is increased during an interval to reduce the chance that other stations gain access to the shared medium during that interval, and the priority level is restored to its normal level following the interval.
