Abstract:
A method for determining a precoding vector for precoding data to be transmitted to a wireless device, includes receiving first channel state information of a channel between a first wireless device and a first base station. The first channel state information is received by the first base station from the first wireless device. The method includes receiving first channel gain information of a channel between a second wireless device and the first base station. The first channel gain information is received from the second base station. The method includes receiving a first signal strength parameter from the second base station and a first interference strength parameter from the second base station and maximizing a common signal to interference noise ratio parameter to obtain a precoding vector for precoding data to be transmitted to the first wireless device.
