Abstract: 본 발명은 이동통신시스템에서 자원 할당 맵 구성 방법에 관한 것이다.
이를 위하여, 이전 프레임에서 할당되거나 고정적인 할당으로 예약된 무선자원을 포함하는 무선자원에 대하여 대역 선택적 무선자원(Localized Resource Block: Localized RB)과 대역 비선택적 무선자원(Distributed Resource Block: Distributed RB)을 동시에 할당하기 위해 계층적 패턴 방식을 사용하는 맵 구성 방법은 우선, 예약되거나 사용되지 않는 무선자원과 현 프레임의 맵에서 새롭게 자원 할당을 수행할 무선자원을 분류하여 표현한다. 이후, 현재 프레임에서 자원을 할당할 무선자원에 대해서는 Localized RB(Resource Block)와 Distributed RB를 분류하여 표현하고 Localized RB에 대해서는 인덱스 패턴 방식을 사용해 할당 정보를 표현하고, Distributed RB에 대해서는 토글 패턴 방식을 사용해 자원 할당 정보를 표현한다.
이러한 본 발명에 따른 계층적 패턴을 이용한 자원 할당 맵 구성 방법은, 각 단말에게 자원 할당 정보를 알리기 위한 맵의 크기를 줄일 수 있으며, 이전 또는 다른 맵에 대한 수신 오류에 관계없이 각 이동 단말에 할당된 무선자원을 정확하게 알릴 수 있다.

Abstract: PURPOSE: A channel estimating method in a wireless communication system is provided to minimize errors due to a reception time difference. CONSTITUTION: A receiver receives an error correction signal which compensates for an error in a signal of a sub-carrier from a transmitter(S300).

Abstract: PURPOSE: A terminal and a communication method thereof are provided to offer a wireless communication service even if a base station has damage. CONSTITUTION: A processor(132) of a terminal is connected to an RF(Radio Frequency) module(136). When the terminal applies electronic wave interference to a lower terminal, the processor controls the maximum transmission power of an uplink relay area and a maximum transmission power of a downlink access area. The size of the maximum transmission power in the downlink access area is smaller than the size of the maximum transmission power in the uplink relay area. The size of the maximum transmission power in the downlink access area is reduced before radio wave interference is generated. [Reference numerals] (132) Processor; (134) Memory; (136) RF module;
