    摘要： Vector Control Entity and method therein for Disorderly Leaving Events, DLEs, causing Sudden Termination Change in a DSL system. The method comprises, when a DLE occurs on a line m in a vectored group of DSL lines, and the transmission on line m is, at least partly, continued: obtaining at least one error sample from CPEs connected to other lines in the vectored group of DSL lines, and calculating an estimate of the channel coefficients, H′, changed due to the DLE. The estimate is calculated based on the at least one error sample, and thus a channel estimate is provided. The method further comprises modifying a downstream precoder, based on the channel estimate, such that retraining of the other lines in the vectored group due to the DLE is avoided. The estimate of the channel coefficients is calculated based on the model H′=H+CΛH.

    摘要： Disclosed is a method performed by a base station (200) in a wireless communication system for controlling communication resources to a plurality of antenna sites (231, 232, 233, 234) of the base station, the base station providing communication resources as a number of antenna carriers providing IQ data flows (IQ1, IQ2, IQ3) to the plurality of antenna sites. The method comprises: estimating (302) traffic load on individual of the plurality of antenna sites (231, 232, 233, 234), and distributing (312) the number of antenna carriers to the plurality of antenna sites based on the estimated traffic load on individual of the plurality of antenna sites.

    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.
