ELECTRONIC DEVICE AND METHOD FOR PROCESSING SIGNAL IN MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM

原文（中国語）

A method performed by a radio unit (RU) is provided. The method includes obtaining, by the RU from a digital unit (DU), first cell information with respect to a first cell and second cell information with respect to a second cell, based on the first cell information and the second cell information, identifying, by the RU, at least one first multiple input multiple output (MIMO) layer for the first cell and at least one second MIMO layer for the second cell from among a plurality of MIMO layers associated with memory of the RU, based on the first cell information, identifying, by the RU, first address information for the at least one first MIMO layer from a first precoding matrix for the first cell and a precoding matrix for the plurality of MIMO layers, based on the second cell information, identifying, by the RU, second address information for the at least one second MIMO layer from a second precoding matrix for the second cell and the precoding matrix, and storing, by the RU on the memory, the precoding matrix identified based on the first precoding matrix, the second precoding matrix, the first address information, and the second address information.
