Abstract:
1. A method for receiving data from a plurality of base stations in a wireless communication system using an Orthogonal Frequency Division Multiple Access (OFDMA), the method performed by a mobile station and comprising: receiving pilot signals from the plurality of base stations via downlink channels, each of the pilot signals distinguished from each of the other pilot signals based on an identifier of each of the plurality of base stations; acquiring information for phases of each of the downlink channels from a corresponding one of the plurality of base stations based on a corresponding one of the pilot signals; and receiving signals including same data from the plurality of base stations using a same time-frequency resource, wherein a phase of each of the downlink channels is compensated based on the acquired information, and wherein the time-frequency resource comprises one or more subcarriers in a frequency domain and one or more OFDM symbols in a time domain.
