The invention relates to methods for determining the interference variability of a precoding matrix set, and the use of same for purposes of scheduling and precoding matrix set selection. The precoding matrix set used by an interferer base station is evaluated by the mobile terminal which experiences the intercell interference from the interferer base station. The mobile terminal is informed about the precoding matrices of the precoding matrix set used by the base station. The mobile terminal measures the radio channel to the interferer cell, and then estimates based on the measured radio channel and with the knowledge on the particular precoding matrices of the precoding matrix set, the interference variability of the precoding matrix set. The interference variability may be reported to the serving base station of the mobile terminal, and thus considered for scheduling decisions by the serving base station referring the mobile terminal. |
