MULTIPLEXING CONTROL AND DATA IN ONE RESOURCE BLOCK

A method for operating a control node for a wireless communication system and comprises the step of creating a data frame defined by a frequency band and a time frame, comprising a plurality of data elements, wherein each data element is define 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, wherein the data elements of a 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, and wherein the second subset comprises data elements of said resource block not used for control data for controlling said receiving node. 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. The method comprises the further steps of 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 and transmitting the data frame to the receiving node.
