The embodiments of the invention relate to a method and a transmitter apparatus for generating and transmitting channel feedback. The method contains the steps of determining at least one first quality value averaged over a long term time interval for a first transmission channel (TC1) from a first antenna system (AS1) of a radio communication system (RCS) to an antenna system (AS) of a network node (MS) containing the transmitter apparatus and at least one second quality value averaged over the long term time interval for at least one second transmission channel (TC2, TC3) from at least one second antenna system (AS2, AS3) of the radio communication system (RCS) to the antenna system (AS) of the network node (MS), determining a distribution of radio resource units of a predefined feedback radio resource based on the at least first quality value and the at least second quality value, transmitting to a receiver apparatus (BS1) a long term feedback containing the at least one first quality value and the at least one second quality value, and transmitting with a short term time interval smaller than or equal to the long term time interval to the receiver apparatus (BS1) a short term feedback containing first short term information for the first transmission channel (TC1) and at least second short term information for the at least second transmission channel (TC2, TC3) using the distribution of radio resource units. The embodiments of the invention further relate to a method and a receiver apparatus for receiving and retrieving channel feedback at a receiver apparatus. The method contains the steps of receiving from a transmitter apparatus a long term feedback containing the at least one first quality value and the at least one second quality value, receiving from the transmitter apparatus with the short term time interval the short term feedback using the distribution of radio resource units, and determining the first short term information and the at least second short term information from the short term feedback based on the distribution of radio resource units.
