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.
