METHOD AND DEVICE FOR SIGNAL TRANSMISSION IN A MULTI-NODE SYSTEM

摘要

Provided are a method and device for signal transmission in a multi-node system comprising: a plurality of geographically distributed nodes; and a base station which is linked to and controls each of the plurality of nodes. The method comprises the steps of: mapping a plurality of code words onto a plurality of streams; mapping the plurality of streams onto at least one of the nodes in the plurality of nodes; carrying out MIMO precoding in which the streams that have been mapped in the at least one node are mapped to at least one transmission antenna; and transmitting the MIMO precoded signal to a terminal.
