Abstract
A method and apparatus for transmitting an uplink Scheduling Request (SR) are provided. The method includes, obtaining a SR subframe configuration by receiving signaling, and transmitting SR information to a Base Station (BS) by using physical resources of another non-SR channel for transmitting other uplink control information. By applying the present invention, the SR, ACKnowledgement/Non-ACKnowledgement (ACK/NACK) or Channel Quality Indicator (CQI) information is returned to a BS when low Constant Modulus (CM) characteristic of an uplink Component Carrier (CC) is ensured.
