Method and device whereby base station allocates nodes to terminal in a semi-static fashion in multi-node system

摘要

The present invention relates to wireless communication, and more specifically, to a method and device whereby a base station allocates nodes to a terminal in a semi-static fashion in a multi-node system. The method, according to one aspect of the present invention, whereby a base station allocates at least a portion of a plurality of nodes to a terminal in a multi-node system comprising the plurality of nodes and the base station for controlling the plurality of nodes, comprises the steps of: receiving, from the terminal, data showing at least one first node that is preferred among the plurality of nodes by the terminal; and transmitting, to the terminal, first data for allocating the first node(s) to the terminal. The first data may comprise pilot data which is required by the terminal in order to transmit, to the base station, feedback data concerning the first node.

1. A method of assigning at least some of a plurality of nodes to a terminal at a base station in a multi-node system including the plurality of nodes and the base station controlling the plurality of nodes, the method comprising:
receiving, by the base station from the terminal, information indicating at least one first node preferred by the terminal among the plurality of nodes; and transmitting, by the base station to the terminal, first information for assigning the at least one first node to the terminal, wherein the first information includes pilot information necessary to transmit feedback information for the at least one first node to the base station, wherein the feedback information includes at least one of a channel quality indicator (CQI) and a precoding matrix index (PMI), and wherein the pilot information includes a reference signal (RS) for measuring the CQI or the PMI.
