摘要： A method of managing a relay path in a mobile multi-hop relay (MMR) environment is provided. A relay station (RS) discovers a link quality of neighboring RSs, which is necessary for managing a path, and reports the link quality to a base station (BS). The BS selects an optimal path having a tree-structure based on the reported link quality and informs the RS. Thus, wireless resources can be efficiently used.

摘要： Provided is a method and system for estimating a channel in a wireless communication system. An interference coefficient is calculated based on a known structure of a pilot, and a channel value in a frequency domain is estimated. A channel value in a time domain is obtained by transforming the channel value in the frequency domain and the channel delay values are subtracted from the channel value in the time domain, thereby cancelling interference.

摘要： A communication method according to the present invention includes receiving MAP in formation, acquiring an initial scheduled frame number and a current frame number from the MAP information, calculating the difference between the initial scheduled frame number and the current frame number, comparing the difference between the initial scheduled frame number and the current frame number with a reference value and setting a scheduled frame number, and performing transmission or reception in the scheduled frame. Therefore, even though a MAP loss occurs, the mobile station can receive only downlink data effective in downlink, thereby reducing power consumption for unnecessary reception, and can exactly perform transmission in a frame in which it should transmit in uplink.

Further, during the modulation and demodulation, the symbol offset is changed to create various modulated and demodulated signals.
