  • Patent number: 10944678
    Abstract: A method for assisting in multipoint data flow control in a wireless communication system having a number, n+1, where n?1, of wireless-transmission points. The method comprises obtaining, for each of the wireless-transmission points, a round trip time of a present sampling period for data travelling to a user equipment via a respective wireless-transmission point and an acknowledge message travelling back. A round trip time skew is computed for the present sampling period for individual wireless-transmission points. The round trip time skew is a difference between the obtained round trip time of a respective wireless-transmission point and a reference value. A reference round trip time value is provided for each wireless-transmission point in dependence of the round trip time skews. A rate control signal is generated, for each of the wireless-transmission points, in dependence of a respective reference round trip time value. Corresponding arrangements are also disclosed.

  • Patent number: 10728867
    Abstract: The solution presented herein controls a transmission timing of data from multiple transmission points to synchronize the data reception at a receiver to within pre-specified limits. To that end, a skew timing is determined from a difference between a second delay (a transmission time between the master node and a second slave node) and a first delay (a transmission time between a master node and a first slave node). A deadzone mapping is applied to the initial liming error (determined from a difference between a reference skew timing and the skew timing) to determine a final timing error. The deadzone mapping is configured to adjust the initial timing error responsive to a comparison between the initial timing error and a timing error range. The first and second delays are controlled using the final timing error to keep the skew timing within the timing error range.

  • Patent number: 10701650
    Abstract: A multi-point transmission system comprising a plurality of slave nodes (300) for transmitting data to a wireless receiver is described herein. An outer feedback loop and a plurality of inner feedback loops (100) connecting the plurality of slave nodes (300) to a master node (200) controls the timing skew of each slave node (300) using measurements provided by the slave nodes (300) to substantially synchronize the receipt of the transmitted data at the wireless receiver. In so doing, the solution presented herein provides improved multi-point control for any number of transmission points, which improves capacity, and solves the potential flow control problems associated with ultra-lean transmissions.

  • Patent number: 10694425
    Abstract: The solution presented herein manages the feedback from multiple transmission points by reducing the amount of feedback provided by one or more slave nodes to a controlling master node. To that end, methods and apparatus are provided that determine whether there is a need for the slave node to provide feedback to the master node. Responsive to this determination, the methods and/or apparatus operate the master and/or slave node in a reduced feedback mode that manages the feedback provided by the slave node to the master node such that an amount of feedback provided by the slave node when operating in the reduced feedback mode is less than an amount of feedback provided by the slave node when operating in a full feedback mode.
