JOINT ENCODING OF RANK AND CQI FEEDBACK FOR COMP

摘要

A method to reduce feedback overhead for CoMP operation is described. The method includes deriving a set of CSI for a coordinated multi-point transmission received at a UE over a plurality of radio links. Each CSI of the set of CSI pertains to a radio link of the plurality of radio links. The plurality of radio links includes a first link from a serving transmission point and at least one multi-point link from at least one non-serving transmission point to the UE. The method also includes jointly encoding at least two CSI from the set of CSI. Apparatus and computer readable media are also described.
