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.

Abstract: A terminal device obtains a first group of parameters corresponding to a first mode. A network device obtains a second group of parameters corresponding to the first mode, where the first group of parameters correspond to the second group of parameters. When a compatibility problem exists between the terminal device and the network device, the terminal device initiates initial access to the network device based on the first group of parameters, and the network device accepts, based on the second group of parameters, the initial access initiated by the terminal device.
