Abstract
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 f…
