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 user equipment (UE) is provided for transmitting an uplink signal in a wireless communication system The UE sets up a sounding reference signal (SRS) configuration for a first serving cell that includes information for an SRS transmission, and determines an SRS subframe in which an SRS and a physical uplink shared channel (PUSCH) for the first serving cell are simultaneously triggered according to the SRS configuration. If a SRS transmission on the SRS subframe for the first serving cell is overlapped with an uplink transmission for a second serving cell, the UE transmits the SRS in the SRS subframe if a total uplink transmission power does not exceeds the UE's maximum transmit power on the overlapped portion. If the SRS is triggered by the SRS configuration and timing advance groups are configured to the UE, the UE transmits the PUSCH on the SRS subframe for the first serving cell.
