摘要:
Provided are a cell searching method and an apparatus in a multi-carrier system. A terminal acquires a first physical cell identity (PCI) for a first downlink component carrier, and acquires an expanded PCI for a second downlink component carrier. A first downlink reference signal through the first downlink element carrier is transmitted on the basis of the PCI, and a second downlink reference signal through the second downlink component carrier is transmitted on the basis of the expanded PCI.

The present invention relates to a wireless communication system. Specifically, the invention relates to a method for configuring a component carrier at a base station in a wireless communication system, comprising the steps of determining whether initial access is permitted to a user equipment with respect to a downlink component carrier; and transmitting a synchronization channel signal and a broadcast channel signal to at least one user equipment via the downlink component carrier, wherein the initial access permission is applied to said at least one user equipment by modifying at least one of the synchronization channel signal and the broadcast channel signal.

Provided are a synchronization acquisition method and apparatus in a multi-carrier system. A terminal acquires the synchronization for a first downlink component carrier by detecting a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in the first downlink component carrier. The terminal acquires the synchronization for a second downlink component carrier by detecting a reference signal in the second downlink component carrier.

摘要:
The present invention discloses a method in which user equipment receives control information in a wireless communication system adopting carrier aggregation. In detail, the method comprises the steps of receiving a control region via one or more component carriers from among a plurality of component carriers transmitted by a base station, and performing a blind decoding process on the control region to obtain control information allocated to the user equipment, wherein the control region includes control information for said one or more component carriers or control information for the rest of the component carriers.

The present invention relates to a method for a terminal for transmitting an uplink control signal, i.e., an ACK/NACK (Acknowledgement/Negative-ACK) signal, in a wireless communication system. In particular, the method comprises: mapping part of the ACK/NACK signals to selection information, which is composed of a combination of message areas and reference signal areas; independently selecting one message area and one reference signal from a plurality of control channel resources that are located in the same resource block, based on the mapped selection information; allocating the selected message area to the other ACK/NACK signals; and transmitting the ACK/NACK signal to a base station by using the selected message area and the selected reference signal area.

The present invention discloses a method in which a terminal transmits an acknowledgement/negative acknowledgement (ACK/NACK) signal in a wireless communication system. In detail, the comprises the steps of allocating a first control channel resource to the ACK/NACK signal and a second control channel resource to a channel quality information (CQI) signal, determining the transmission power of the first control channel resource and the transmission power of the second control channel resource in accordance with a preset priority, and transmitting the ACK/NACK signal and the CQI signal to a base station using the control channel resources and the transmission powers corresponding thereto.
