A method of controlling radio transmission in a wireless communication network is described, the method comprising a radio device (10; 400; 700) receiving an indication of a set of first signals (31, 32, 33, 34, 35, 36) for associating the set of first signals (31, 32, 33, 34, 35, 36) with a second signal. The method comprises the radio device (10; 400; 700) receiving at least one of the first signals (31; 32, 33, 34, 35, 36); and in response to the indication, the radio device (10; 400; 700) estimating at least one parameter of the second signal based on the at least one received first signal. The method further comprises, based on the at least one estimated parameter, the radio device (10; 400; 700) processing at least one radio transmission (21) from the wireless communication network.
