摘要： Methods and arrangements for adapting the load in a cell based on information on upcoming events related to a backhaul link. Further, the upcoming events related to the backhaul link may be delayed in order to give enough time for an RBS to complete activities related to the load adaptation. Thus, UEs may be handed over to neighboring cells proactively, before the cell becomes overloaded due to events related to the backhaul link.

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.

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.
