Method for transmitting and receiving signals using collaborative MIMO scheme |
摘要 |
A method for reducing inter-cell interference and a method for transmitting a signal by a collaborative MIMO scheme, in a communication system having a multi-cell environment are disclosed. An example of a method for transmitting, by a mobile station, precoding information in a collaborative MIMO communication system includes determining a precoding matrix set including precoding matrices of one more base stations including a serving base station, based on signal strength of the serving base station, and transmitting information about the precoding matrix set to the serving base station. A mobile station in an edge of a cell performs a collaborative MIMO mode or inter-cell interference mitigation mode using the information about the precoding matrix set collaboratively with neighboring base stations. |

1. A method for selecting a transmission mode by a serving base station, the method comprising:
receiving, from a mobile station, mode selecting information associated with one transmission mode among a collaborative multiple-input multiple-output (MIMO) mode and an inter-cell interference mitigation mode, wherein the one transmission mode is selected by the mobile station based on information associated with interference generated in a specific frequency band by at least one neighboring base station. |
