Abstract: A method for controlling transmission powers by a communication apparatus in a wireless communication system supporting a plurality of component carriers. When a sounding reference symbol (SRS) transmission overlaps with a physical uplink shared channel (PUSCH) transmission in a time domain, the communication apparatus checks whether a total of a PUSCH transmission power for the PUSCH transmission on a first component carrier and a SRS transmission power for the SRS transmission on a second component carrier exceeds a maximum transmission power configured for the communication apparatus, and drops the SRS transmission if the total of the PUSCH transmission power and the SRS transmission power exceeds the maximum transmission power configured for the communication apparatus.

Abstract: A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.

Abstract: A method for transmitting channel quality information for a downlink channel; a user equipment (UE) therefore; a method for receiving channel quality information for a downlink channel; and a base station therefore are discussed. The method for transmitting channel quality information for a downlink channel includes according to one embodiment receiving, by a user equipment (UE), configuration information on periodic channel state information (CSI) reporting by higher layer signaling; determining, by the UE, a channel quality information index at least based on a number of a specific resource element; and transmitting the determined channel quality information index to a base station. The number of the specific resource element is determined based on a UE-specific reference signal overhead. A resource element allocated for a Channel Status Information-Reference Signal (CSI-RS) is regarded as the specific resource element regardless of transmitting the CSI-RS.

Abstract: A method of transmitting pilot signals in a system which performs communication using two or more earners comprises transmitting first pilots and second pilots from at least one user equipment to a base station, the first and second pilots, which are transmitted from the at least one user equipment, being multiplexed by code division multiplexing, and the first and second pilots, which are transmitted from a specific user equipment, having different transmission powers, and transmitting data from the at least one user equipment to the base station depending on the first pilots and the second pilots. Since many UEs can transmit CQ pilots, exact channel estimation can be performed and thus communication efficiency can be improved.

Abstract: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.
