Patent number: 11245436Abstract: A method for initialization of a group of customer premises equipment devices (CPEs) during a training that registers capabilities of the CPEs is disclosed, wherein at least one CPE registers late to the training and cannot be registered. The method includes determining capabilities of the CPEs during a joining phase of the training, wherein it is determined whether a CPE device is capable of employing vectoring, and placing in a hold status the at least one CPE that registers late by keeping a line active that is coupled to the at least one CPE. The method further includes providing another joining phase after the joining phase to register the at least one CPE that registers late.Type: GrantFiled: February 17, 2020Date of Patent: February 8, 2022Assignee: Lantiq Beteiligungs-GmbH & Co.

Patent number: 11042212Abstract: Within a communication system that includes multiple communication channels, a low-power mode of operation and a higher-power mode of operation are provided. Each channel is allocated to one of several groups, based on criteria such as whether power is allocated to that channel in low power mode, and whether power was allocated to that channel in a previous high power mode. Initial power levels for each channel for each mode are approximated using an interpolation rule known to both the receive and the transmitter. The system switches between modes according to a PMD pre-defined schedule. When a new power mode begins, the receiver measures signal power received on each channel and then transmits corrective information sufficient to allow adaptation of power levels to achieve PMD pre-defined levels of received power.Type: GrantFiled: February 5, 2018Date of Patent: June 22, 2021Assignee: Lantiq Beteiligungs-GmbH & Co.

Patent number: 10827388Abstract: According to one embodiment, a connection is established between a first communication device and a second communication device in accordance with one or more communication layers. Each communication layer is associated with a standard structure and protocol. An ad hoc communication layer structure and/or protocol are determined at the first communication device. The ad hoc communication layer structure and/or protocol are communicated to the second communication device. One or more of the standard structures and/or protocols are replaced at the first communication device with the ad hoc communication layer structure and/or protocol responsive to the second communication device acknowledging acceptance of the ad hoc communication layer structure and/or protocol.Type: GrantFiled: November 23, 2016Date of Patent: November 3, 2020Assignee: Lantiq Beteiligungs-GmbH & Co.

Patent number: 10566999Abstract: A coded signal is received via a physical channel. The coded signal is encoded by a parity check matrix. In some examples, the coded signal is low density parity check-encoded. The coded signal is decoded to determine a result signal. Said decoding alternatingly updates, for each one of a number of iterations, bit node values representing bits of the result signal and check node values representing constrains of the parity check matrix. In some examples, the decoding determines the result signal at a first precision and updates at least partly at a second precision which is lower than the first precision. In further examples, the number of iterations is dynamically adjusted.Type: GrantFiled: November 18, 2015Date of Patent: February 18, 2020Assignee: Lantiq Beteiligungs-GmbH & Co.
