Abstract: A solution for determining in a radio receiver a data sequence indicating transmission parameters and a spreading factor applied to a frame before receiving the whole frame in the radio receiver. According to the provided solution, the transmission parameters and the spreading factor are determined from received data of a partially received data sequence indicating the transmission parameters of the frame. The received portion of the data is despread with known possible spreading factors and the despread data is compared with corresponding data of known possible transmitted data sequences. Spreading factor-data sequence combination resulting in the best match with the received data is then determined to be the most probably transmitted data sequence. The results of comparison with respect to the spreading factor may be combined with another spreading factor determination procedure for more reliable detection of the correct spreading factor.
