摘要： A method for transmitting channel status information (CSI) of downlink multi-carrier transmission includes generating the CSI including at least one of a rank indicator (RI), a first precoding matrix index (PMI), a second PMI and a channel quality indicator (CQI) for one or more downlink carriers, the CQI being calculated based on precoding information determined by a combination of the first and second PMIs, determining, when two or more CSIs collide with one another in one uplink subframe of one uplink carrier, a CSI to be transmitted on the basis of priority, and transmitting the determined CSI over a uplink channel. If a CSI including an RI or a wideband first PMI collides with a CSI including a wideband CQI or a subband CQI, the CSI including a wideband CQI or a subband CQI has low priority and is dropped.

摘要： The present invention relates to methods for searching an enhanced physical downlink control channel (E-PDCCH), and a device for supporting the methods. According to one embodiment of the present invention, a method for searching an enhanced physical downlink control channel (E-PDCCH) in a wireless access system can comprise the steps of: performing a blind decoding on a control channel region and searching a legacy physical downlink control channel (PDCCH); and searching the E-PDCCH on the basis of the searched legacy PDCCH. In this case, in a subframe to which the E-PDCCH is allocated, using all symbols of the subframe from a first symbol to a third symbol is always preferred for allocation of the legacy PDCCH.
