Patent ID: 8583128

Claim:
A method for mapping physical control channels onto radio resource element groups, the method comprising: mapping physical control channels of a first mobile radio technology onto a first set of radio resource element groups, wherein the first mobile radio technology operates within a first bandwidth, the first bandwidth being within a frequency band of a component carrier; mapping physical control channels of a second mobile radio technology onto a second set of radio resource element groups, wherein at least one radio resource element group of the second set of radio resource element groups is within the first bandwidth and at least one radio resource element group of the second set of radio resource element groups is outside the first bandwidth, and within the frequency band of the component carrier; generating mapping information specifying the mapping of physical control channels of the first mobile radio technology onto the first set of radio resource element groups; and generating mapping information specifying the mapping of physical control channels of the second mobile radio technology onto the second set of radio resource element groups.
