Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and a radio base station for interleaving control channel data to be transmitted in a communication system.

SOLUTION: The method comprises: a step of grouping the control channel elements CCE into a first order of control channel symbol groups (601); a step of determining a number of available symbol group positions of control channel transmission resources (602); a step of adding symbol groups having dummy values or zeros to the first order of control channel symbol groups (603); a step of interleaving the first order of the control channel symbol groups to obtain a second order as a result (604); a step of performing a cyclic shift of the second order (605); and a step of mapping the cyclically shifted second order of control channel symbol groups to the control channel transmission resources(606).
