摘要： Method and transmitting node for adjusting transmission over xDSL lines connected to the transmitting node. The method involves transmitting (1006) a first signal A1 on a first line (304), and transmitting (1008) a second signal A2 on a second line (306), the second signal A2 being related to the first signal A1. The method further involves adjusting (1010) the transmission of the second signal A2 on the second line (306), such that a contribution from the second signal A2 interferes constructively with a signal A1' at the second end (304:2) of the first line (304), where the signal A1' represents the signal A1 having propagated through the first line.

摘要： A first network node(11) of a cellular system for communication with a second network node (21) over a twisted pair wire (23). The first network node comprises a receiver (123) for receiving, over the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted from a high frequency signal having a frequency higher than the frequency of the intermediate frequency signal by the second network node, and a down-converter (121) for converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal. The first network node also comprises an up-converter (122) for converting a received low frequency signal to an intermediate frequency signal having a frequency higher than the frequency of the low frequency signal, and a transmitter (124) for transmitting, over the twisted pair wire, the intermediate frequency signal to the second network node for subsequent conversion into a high frequency signal with a frequency higher than the frequency of the intermediate frequency signal at the second network node. The invention also relates to corresponding methods for taking care of downlink signals and uplink signals, respectively.

摘要： Method and arrangement in a Vector Control Entity for efficient selection of which crosstalk to cancel when applying partial vectoring in a DSL communication system. The method comprises calculating a respective crosstalk effect indicator, CEI ij , for the crosstalk from each line j of a plurality J of lines in a vectoring group, to a plurality of tones S i of a line i in the vectoring group, based on the strength of the crosstalk from each line j to line i, and thus providing one CEl i -value, associated with the plurality S j of tones, per line j. The method further comprises allocating partial-vectoring resources to cancellation of crosstalk, based on the calculated CEIs. The arrangement is adapted to enable the performance of the above described method.

摘要： Method and arrangement in a Vectoring Control Entity, VCE,for handling disorderly events in a Digital Subscriber Line, DSL, system. The method involves a number of actions, to be performed when a disorderly event occurs on a line min a vectored group of DSL lines, and the transmission on line m is continued. The method comprises obtaining(104)error samples from Customer Premises Equipments, CPEs, connected to other lines in the vectored group of DSL lines. The method further comprises -calculating an estimate of the channel coefficients changed due to the disorderly event,based on the error samples, thus providing a partial channel estimate. Further, the method comprises -modifying (110) a downstream precoder, at least partly based on the partial channel estimate, such that retraining of the other lines in the vectored group due to the disorderly event is avoided. The arrangement is adapted to enable the performance of the above described method.

摘要： Method and arrangement in a Vector Control Entity (801) for enabling a fair bit rate distribution among lines of similar priority in a vectoring group, when applying partial vectoring in a DSL communication system, The method comprises calculating (704) a rate balancing metric, RBM, for each line i within a priority group A, indicative of the ratio between the bit rate of a line i with a current vectoring resource allocation, and the estimated bit rate of line i assuming approximately no crosstalk within the vectoring group. The method further comprises allocating (708) partial-vectoring resources to the line/s within the group A, based on the calculated RBMs, such as to reduce the difference in RBM between the lines. The method further comprises calculating (710) an updated RBM for any line within the group A subjected to changes in vectoring resource allocation. The method may be iterated until certain criteria are fulfilled. The arrangement is adapted to enable the performance of the above described method.

摘要： A device (10) for providing access to a data communication network for modems (22, 24, 26, 28) is connected to the modems via a set of communication lines (14, 16, 18, 20). A first group of modems (22, 24, 26) support vectoring, and a second group do not support vectoring. The device investigates the expected value of an element in a synchronisation interval to be received by a modem (28) in the second group, investigates the value of an element of at least one data sequence assigned to the communication line of this modem, compares the values, selects the element of the investigated data sequence for transmission if the element value corresponds to the expected value and transmits the selected element together with corresponding elements of a number of pilot sequences assigned to the first group of modems via the set of communication lines.

摘要： In a vectoring-capable DSL system, power can be saved by a low power mode wherein data transmission is reduced or halted, but synch symbols continue to be transmitted, so that estimation of crosstalk coefficients may continue during the low power mode. When crosstalk coefficient estimates are up to date, a line may exit low power mode without causing problematic changes of crosstalk noise in other lines, since the vectoring functionality will eliminate or reduce the crosstalk.

摘要： When data retransmission is used to handle errors caused by impulse noise, buffer memory requirements may be reduced and/or data rate increased by detecting impulse noise at the transmitting equipment and initiating retransmission in response to such detection rather than waiting for a retransmission indication from the receiving end. The decision to retransmit may be made dependent on the strength or other properties of the detected noise burst. The decision criterion may be made adaptive by correlating noise burst properties with received retransmission indications or the absence thereof.
