Method and apparatus for performing effective feedback in wireless communication system supporting multiple antennas
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..

Channel traffic congestion avoidance in a mobile communication system
A mobile station detects whether there is congestion in a cell by monitoring a first channel fix downlink messages and decoding the messages to see if the decoded messages indicate congestion, where the first channel is a common control channel (ccch). For the case in which the mobile station determines from the decoded messages that there is no congestion, the mobile station initiates a random access procedure by transmitting a request message uplink on a random access channel (rach).
