Abstract: The present disclosure relates to a method for facilitating synchronization in a wireless communication system. A number sequence of length L is defined. The number sequence is mapped on a first set of discrete Fourier frequency coefficients. A second set of discrete Fourier frequency coefficients is generated by frequency shifting the first set of discrete Fourier frequency coefficients. The second set of discrete Fourier frequency coefficients is transformed into a time domain signal.

Abstract: A method can be used for facilitating a random access procedure between a first transceiver and a second transceiver within a cell. The first transceiver selects a signature sequence from a set of signature sequences, incorporates the signature sequence into a signal, and transmits the signal to the second transceiver. The set of signature sequences being obtained from a Zadoff-Chu sequence with zero correlation zone.

Abstract: The invention concerns a method for precoding in an open loop transmission communications system, wherein the method includes precoding data at each of M REs with a precoding matrix, precoding each of DM-RSs with one column of a precoding matrix which is same as that used for precoding M data REs. The method is distinguished by using at least L≧2 different precoding matrices from a set of precoding matrices W to precode the M REs and the E allocated REs such that REs precoded with a first precoding matrix are interleaved with REs precoded with at least one additional, different precoding matrix and the number of used precoding matrices L is adapted to the transmission rank r and number N of available DM-RS. The invention further concerns a radio transmitter and a user equipment.
