Abstract: Training, refreshing and/or updating Ethernet link partners for silent channels and/or silent directions of channels may be determined based on control parameters. This may be used to improve energy efficiency in Ethernet communication. Control parameters may comprise a default value and/or may be determined based on prior training, refreshing and/or updating. New values for the control parameters may be generated based on a magnitude of change between current and prior control parameter values or based on performance such as bit error rate. User input may be utilized to determine when to execute the training, refreshing and/or updating. The training, refreshing and/or updating may be done for one or more of a near-end crosstalk canceller, alien near-end crosstalk canceller, far-end crosstalk canceller, alien far-end crosstalk canceller and echo canceller. After the training, refreshing and/or updating, the silent channels may transition to active and/or may remain silent.

Abstract: An Ethernet link may comprise silent and active channels and may support energy efficient Ethernet communication. Training parameters from the one or more active channels may be utilized for determining and/or adjusting training parameters for silent channels prior to activation. Training parameters for silent channels may be determined based on copying training parameters from active channels. Determination of training parameters for silent channels may be based on a weighted average of the active channel training parameters. A delta between active channel training parameters from a prior time and subsequent time may be utilized to determine a correction factor for adjusting training parameters for a silent channel from a prior time. Silent channels may be adjusted based on active channel training parameters and then subsequently may be trained. Training parameters may be adjusted for one or more of an echo canceller, a near-end crosstalk canceller and a far-end canceller.

Abstract: [Object] To ensure a maximum data transfer rate to achieve an improvement in throughput. [Solving Means] A CPU 114 determines whether or not time-dependent interference is present during communication with a communication partner.

Abstract: A system and method is disclosed for resource block-specific control signaling in a communication system. Communication data is transmitted using a transmission channel comprising a plurality of resource blocks defined by allocating time-frequency slots in a transmission resource. Resource block control information is transmitted in a “feed-forward” manner to a user end (UE) or group of UEs using channels physically mapped into scheduled resource blocks (RBs) for that user or group of users. Embodiments of the invention provide an RB-specific control channel that comprises RB control elements that are embedded within scheduled resource blocks. The invention, therefore, reduces the amount of control information that must be transmitted by common or shared control channels.
