PERIODIC CHANNEL STATE INFORMATION REPORTING FOR COORDINATED MULTIPOINT (CoMP) SYSTEMS

摘要

Technology for periodic channel state information (CSI) reporting in a coordinated multipoint (CoMP) scenario is disclosed. One method can include a user equipment 5 (UE) generating a plurality of CSI reports for transmission in a subframe for a plurality of CSI processes. Each CSI report can correspond to a CSI process with a CSIProcesslndex. The UE can drop CSI reports corresponding to CSI processes except a CSI process with a lowest SCIProcesslndex. The UE can transmit at least one CSI report for the CSI process to an evolved Node B (eNB).
