摘要： A method and arrangement are disclosed in a Vector Control Entity 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 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 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 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.

The method comprises calculating a respective crosstalk effect indicator, CEIij, for the crosstalk from each line j of a plurality J of lines in a vectoring group, to a plurality of tones Si 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 CEIi-value, associated with the plurality Sj 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： A network node that serves a host cell in a cellular communication system transmits, at (a) first time interval(s), first control channel information on a control channel that extends over a first bandwidth of a radiofrequency spectrum. The first control channel communicates information necessary to enable a first type of communication device to receive data from the host cell. The first type of communication device can receive first bandwidth-wide signals. At (a) second time interval(s), second control channel information is transmitted on a second control channel of a first M-cell. The second control channel occupies a second bandwidth that is smaller than the first bandwidth. The second time interval(s) do(es) not coincide with any of the first time interval(s). A second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device is thereby made capable of being served by the node.

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.
