A method of controlling radio communication in a cellular network supporting radio communication based on a first configuration which organizes a time-frequency space in first resource elements and radio communication based on a second configuration which organizes the time-frequency space in second resource elements and assigns at least one of the second resource elements to a utilization which is in conflict with said radio communication based on the first configuration, the method comprising: a node (100-A,100-B) of the cellular network sending an indication to a communication device (10-A, 10-B), the indication comprising time domain and/or frequency domain information for defining a pattern (300; 450; 550; 600; 610, 620, 630; 810, 820; 930; 980; 1030; 1110, 1120, 1130) comprising at least one of the first resource elements which is to be disregarded by the communication device (10-A, 10-B) when performing radio communication with the cellular network based on the first configuration and/or the second configuration, wherein the at least one first resource element of the pattern (300; 450; 550; 600; 610, 620, 630; 750, 760; 810, 820; 930; 980; 1030; 1110, 1120, 1130) defines a first part of the time-frequency space which overlaps a second part of the time-frequency space defined by the at least one of the second resource elements, characterized in that the indication comprises first time domain and/or frequency domain information for defining a first pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020) of the first resource elements and comprises second time domain and/or frequency domain information for defining a second pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020) of the first resource elements, and wherein the pattern (450; 550; 1030) is an intersection of the first pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020) and the second pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020). a node (100-A,100-B) of the cellular network sending an indication to a communication device (10-A, 10-B), the indication comprising time domain and/or frequency domain information for defining a pattern (300; 450; 550; 600; 610, 620, 630; 810, 820; 930; 980; 1030; 1110, 1120, 1130) comprising at least one of the first resource elements which is to be disregarded by the communication device (10-A, 10-B) when performing radio communication with the cellular network based on the first configuration and/or the second configuration, wherein the at least one first resource element of the pattern (300; 450; 550; 600; 610, 620, 630; 750, 760; 810, 820; 930; 980; 1030; 1110, 1120, 1130) defines a first part of the time-frequency space which overlaps a second part of the time-frequency space defined by the at least one of the second resource elements, characterized in that the indication comprises first time domain and/or frequency domain information for defining a first pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020) of the first resource elements and comprises second time domain and/or frequency domain information for defining a second pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020) of the first resource elements, and wherein the pattern (450; 550; 1030) is an intersection of the first pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020) and the second pattern (410, 420, 430; 510, 520, 530; 710, 720, 730; 1010, 1020).
