Abstract
Provided is a method of applying a transmission diversity scheme in a multiple cell cooperative communication system in which a terminal may receive, from a plurality of base stations, identical data using an identical radio resource. In the method, base stations of a cooperative base station involved in a cooperative communication may apply the transmission diversity scheme using the same resource as time and frequency resources used to apply the transmission diversity scheme in a base station of a serving base station.
Claims8
A mobile communication system, comprising:
- a serving base station precoding transmission data to generate a first data vector and transmitting the first data vector to a terminal;
- and
- a cooperative base station converting a phase of the first data vector to generate a second data vector and transmitting the second data vector to the terminal,
- wherein a phase of the second data vector is a different value for each predetermined duration with respect to at least one of a time and a frequency,
- wherein the phase of the first data vector is converted into another phase for each predetermined duration with respect to at least one of a time and a frequency to thereby generate the second data vector.
A terminal connected with a serving base station, the terminal comprising:
- a receiving unit to receive, from the serving base station, a first data vector generated based on transmission data, and to receive, from a cooperative base station, a second data vector generated by converting a phase of the first data vector;
- and
- a data decoding unit to decode the transmission data using the received first data vector and the received second data vector,
- wherein the phase of the first data vector is converted into another phase for each predetermined duration with respect to at least one of a time and a frequency to thereby generate the second data vector.
