METHOD OF CALCULATING PHASE CORRECTION MATRIX FOR MULTICELL JOINT TRANSMISSION AND METHOD OF FEEDING BACK THE PHASE CORRECTION MATRIX

摘要

PURPOSE: A phase compensating matrix calculation method and feedback method thereof for multi cell cooperation transmission are provided to fix a phase compensation matrix in a block diagonal structure. CONSTITUTION: An estimating unit(410) estimates a first channel between a serving base station and an object terminal and a second channel between an object terminal and a neighboring base center. A calculating unit calculates a first precoding vector and a second precoding vector based on the channels. A determining unit(430) determines a phase compensating matrix having a block diagonal structure based on the first predocing vector and the second precoding vector.
