    Abstract: 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.

    Abstract: A scheme for providing access to 6LoWPAN data in a wireless access network. In one embodiment, a Digital Unit (DU) of the wireless access network is provided with IP bridging functionality for packaging 6LO data as a control channel message. When the DU element receives 6LO data from an external router, the data is packaged in a format specified for a control channel associated with a CPRI link coupling to a Radio Unit (RU). The bridging functionality is operative to transmit the control channel message (including the packaged 6LO data packets) to the RU element based on an address mapping between the destination IP address of the 6LO data packets and an address of the 6LO endpoint coupled to the RU element.

    Abstract: 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, 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 CEli-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.

    Abstract: 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.

    Abstract: In mobile communications networks, requirements on signal distortion may be fulfilled at a lower bit rate, or alternatively quantization noise be reduced for a given bit rate, by including fractional exponent bits in a block floating point format. One or more fractional exponent bits may apply to all samples in the block. Alternatively, fractional bits may apply to sub-blocks within the block. The optimal number of fractional bits depends on the number of samples in the block.
