ASYMMETRICAL FEEDBACK FOR COORDINATED TRANSMISSION SYSTEMS

摘要

[0055] A method includes, in a mobile communication terminal (24), receiving from at least first and second base stations (28A, 28B), which cooperate in a coordinated transmission scheme, signals that are transmitted over respective first and second communication channels. Respective channel measures are calculated for the communication channels based on the received signals. First and second feedback data, which are indicative of the respective channel measures of the first and second communication channels, are formulated such that the first feedback data has a first data size and the second feedback data has a second data size, different from the first data size. The first and second feedback data are transmitted from the mobile communication terminal to at least one of the base stations.
