Abstract
An electronic device operating on a base station side and includes a processing circuit configured to perform control to cause the electronic device to: estimate channel correlation in a first direction among a plurality of terminals communicating with the base station; and in response to that the estimated channel correlation in the first direction among the plurality of terminals satisfies a predetermined condition, transmit a first indication signal to indicate that a second measurement process is to be performed to determine channel information in a second direction after a first measurement process is to be performed to determine channel information in the first direction, and transmit, based on the channel information in the second direction, a second indication signal to indicate a precoding scheme for data to be transmitted from the base station to the plurality of terminals, the precoding scheme including linear precoding or non-linear precoding.
