摘要
The present invention relates to method and apparatus for channel direction information feedback in a heterogeneous system. According to an embodiment of the present invention, a method for channel direction information feedback in a heterogeneous system comprises: determining, for a user equipment, total feedback bits for quantization of channel direction information, based on a trade off between accuracy of channel direction information quantization and reliability of uplink feedback transmission on a predetermined uplink feedback resource, wherein coordinated multi-point transmission between a local base station and a cross base station is performed for the user equipment in the heterogeneous system; and notifying said user equipment of said total feedback bits for quantization of channel direction information that will be conveyed on said predetermined uplink feedback resource. The embodiments of the present invention further relate to corresponding base station, user equipment and computer program product.
