Patent ID: 8861624

Claim:
A method of transmitting a signal of a mobile station that performs communication with a plurality of cells in a wireless communication system, the method comprising: transmitting a preamble and data through an asynchronous channel to a neighboring cell which is not synchronized with the mobile station, wherein a structure of the asynchronous channel includes a preamble region for the preamble and a plurality of data regions for the data, wherein the structure of the asynchronous channel further includes a first cyclic prefix for all of the preamble region and the plurality of data regions to solve ambiguousness of the asynchronous channel, wherein each of the plurality of data regions includes a second cyclic prefix for corresponding data to process inter-symbol interference, wherein the first cyclic prefix is generated by using a last data region among the plurality of data regions, and wherein the second cyclic prefix is generated by using a corresponding data region.
