A solution for determining in a radio receiver a data sequence indicating transmission parameters of a frame before the whole frame has been received in the radio receiver in order to obtain additional pilot symbols. According to the provided solution data is received in one or more time intervals, the data being part of a transmitted data sequence indicating transmission parameters of a frame. The possible data sequences are known to the radio receiver. The received data is compared with corresponding data of each known data sequence, and, based on the comparison, the data sequence which is determined to be closest to the received data is selected. The received data of the data sequence indicating the transmission parameters of the frame is then used as pilot data for channel estimation purposes, for example.
