periodic channel state reporting for time division duplex carrier (tdd) aggregation systems

摘要

The present invention relates to technology for reporting periodic channel state (csi) information. One method may include a user equipment (eu) that identifies a csi reporting situation configured for a secondary cell to report periodic csi to a node based on a secondary cell csi reporting configuration. which may determine that the configured csi reporting situation of the secondary cell used to report periodic csi does not correspond to an uplink subframe (ul) of a primary cell. the eu can transmit periodic csi reporting to the secondary cell to the node using a pusch shared channel in the secondary cell when the periodic csi reporting situation for the secondary cell does not match the ul subframe of the primary cell and an ul-sch (uplink shared channel) is available in a subframe that corresponds to the secondary cell's periodic csi reporting situation.
