A method for operating a control node for a wireless communication system comprising the steps: - creating a data frame defined by a frequency band and a time frame, comprising a plurality of data elements, - wherein each data element is defined by one of a plurality of subcarrier frequencies within said frequency band and one of a plurality of time slots within said time frame, - wherein a resource block comprises a number of data elements adjacent in time and frequency, arranged in a time-frequency grid, - wherein the data elements of the resource block are subdivided into at least a first subset and a second subset; - wherein the first subset comprises first control data for controlling a receiving node, - wherein the second subset comprises data elements of said resource block not used for control data for controlling said receiving node, and - wherein the first subset and the second subset are distributed over the time-frequency grid of the resource block and are arranged in a mixed frequency and/or timely order in the data frame; - checking whether third control data for another receiving node are to be put into the second subset; - scheduling payload data for the receiving node into the second subset if third control data are not to be put into the second subset of data elements; - transmitting the data frame to the receiving node. - creating a data frame defined by a frequency band and a time frame, comprising a plurality of data elements, - wherein each data element is defined by one of a plurality of subcarrier frequencies within said frequency band and one of a plurality of time slots within said time frame, - wherein a resource block comprises a number of data elements adjacent in time and frequency, arranged in a time-frequency grid, - wherein the data elements of the resource block are subdivided into at least a first subset and a second subset; - wherein the first subset comprises first control data for controlling a receiving node, - wherein the second subset comprises data elements of said resource block not used for control data for controlling said receiving node, and - wherein the first subset and the second subset are distributed over the time-frequency grid of the resource block and are arranged in a mixed frequency and/or timely order in the data frame; - wherein each data element is defined by one of a plurality of subcarrier frequencies within said frequency band and one of a plurality of time slots within said time frame, - wherein a resource block comprises a number of data elements adjacent in time and frequency, arranged in a time-frequency grid, - wherein the data elements of the resource block are subdivided into at least a first subset and a second subset; - wherein the first subset comprises first control data for controlling a receiving node, - wherein the second subset comprises data elements of said resource block not used for control data for controlling said receiving node, and - wherein the first subset and the second subset are distributed over the time-frequency grid of the resource block and are arranged in a mixed frequency and/or timely order in the data frame; - checking whether third control data for another receiving node are to be put into the second subset; - scheduling payload data for the receiving node into the second subset if third control data are not to be put into the second subset of data elements; - transmitting the data frame to the receiving node.
