Patent ID: 8855074

Claim:
A method for operating a control node in a wireless communication system, said method comprising: creating a data frame defined by a frequency band and a time frame, said data 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 intervals 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 first receiving node, and wherein the second subset comprises data elements of said resource block not used for control data for controlling said first receiving node; checking whether second control data for a second receiving node are to be put into the second subset; scheduling payload data for the first receiving node into the second subset if second control data for the second receiving node are not to be put into the second subset of data elements; transmitting the data frame to the receiving node.
