Abstract: A method of allocating communication resources for a communication between a transmitter and a receiver in a communication system, the communication resources being divided in time periods and frequency sub-bands. The transmitter receives a channel quality measurement sent by the receiver. The transmitter performs allocation of a first part of the communication resources to the receiver according to the channel quality measurement if allocation of the first part is selected, or allocation of a second part of the communication resources to the receiver if allocation of the first part is not selected. The transmitter informs the receiver of allocated communication resources, and the allocated communication resources being designated for frequency localized channels or for frequency distributed channels.

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 wireless communication system includes at least one transmit node having at least two transmit antenna ports, and at least one receive node having at least one receive antenna port. User information is transmitted between the at least two transmit antenna ports and the at least one receive antenna port on a radio propagation channel. A reconstructed channel state information (R-CSI) for a reconstructed radio propagation channel is computed. The reconstructed radio propagation channel is obtained as an estimated radio propagation channel compensated by a function of an estimated signal power imbalance between the at least two transmit antenna ports. And an indicative of the estimated signal power imbalance and the R-CSI is sent to the at least one transmit node.
