摘要： A method and corresponding system for communicating between stations in a network are presented. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among a plurality of the stations; transmitting from a first station to a second station during a time slot assigned to the first station by at least one of the beacon transmissions; and transmitting from the first station information that grants permission to the second station to transmit during at least a portion of a time slot assigned to the first station.

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.

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. 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.
