Abstract: Provided is a method that a first terminal communicating with a base station directly communicates with a second terminal. In accordance with an embodiment of the present invention, the first terminal determines a first time point at which the first terminal transmits a first signal to the base station or receives the first signal from the base station. The first terminal determines a second time point at which the first terminal transmits a second signal for searching a terminal to the second terminal. The first terminal changes one among the first time point and the second time point when the first time point and the second time point are overlapped.

Abstract: PURPOSE: An apparatus and method for feedback in a wireless mesh system are provided to reduce overheads by providing an HARQ(hybrid automatic repeat request) feedback channel for the wireless mesh system. CONSTITUTION: Data is received in a first sub frame. An HFBCH(HARQ feedback channel) is selected to transmit ACK/NACK(acknowledgement/not-acknowledgement) of the data in a second sub frame corresponding to the first sub frame. The ACK/NACK of the data is transmitted in the selected HFBCH. The HFBCH which can be transmitted from the second sub frame has a mapping relation with an LRU(logical resource unit) of the first sub frame. The first sub frame and the second sub frame are included in a frame which can transmit scheduling information and the data.

Abstract: PURPOSE: A resource allocation method in a mobile communication system is provided to allocate resources efficiently in a high speed mobile communication environment. CONSTITUTION: A resource request is requested from a first mobile station that moves at a first reference speed(S101), and the structure of a first resource block allocated to the first mobile station is determined(S102). The resources are allocated to the first mobile station so that the first and second resource blocks allocated to the second mobile station moving below the first reference speed may be allocated to different frequencies at the same time(S103).
