Abstract: There is provided an improved solution for generating and compressing uplink channel feedback information in a communication system. The solution includes determining, at a user terminal, information related to a condition of at least one channel between the user terminal and at least one communication point of a cooperative multi-point transmission network, and generating feedback information including, for each reporting sub-band, a channel condition of a predetermined resource block and at least one differential channel condition of at least one other resource block within the same reporting sub-band. The generated feedback information may be communicated to a control node of the co-operative multipoint communication network.
