    摘要: Provided are a method and device for allocating a downlink control channel in a wireless communication system. A base station allocates an enhanced physical control format indicator channel (e-PCFICH) to a control region of a plurality of resource blocks (RBs), transmits, to a terminal, an enhanced physical downlink control channel (e-PDCCH) indicator including information for indicating the start position of an e-PDCCH allocated to a data region of the plurality of RBs, and allocates the e-PDCCH to the data region of the plurality of RBs on the basis of the e-PDCCH indicator.

    摘要: Provided is a signal transmitting method of a terminal in a multi-node system including and configured to control a plurality of nodes and a base station connected to each of the plurality of nodes. The method includes: estimating a channel of at least one node by receiving a reference signal from at least one node among the plurality of nodes; selecting a preferred rank and a precoding matrix index by applying at least one precoding matrix to the estimated channel; selecting one of a plurality of codeword-layer mappings (CLMs) by applying a precoding matrix indicated by the rank and the precoding matrix index; and transmitting the selected rank, the selected precoding matrix index, and a CLM indicator to the base station.

    摘要: Provided is a method for transmitting a signal in a multi-node system including a plurality of nodes, and a base station connected to each of the plurality of nodes for controlling the nodes. The method comprises the following steps: transmitting first node-setting information to a first terminal; transmitting second node-setting information to a second terminal; transmitting a signal to the first terminal through a first node group; and transmitting a signal to the second terminal through a second node group, wherein the first node-setting information and the second node-setting information include system parameters which are set differently for each terminal, and the first node group is determined on the basis of the first node-setting information, and the second node group is determined on the basis of the second node-setting information.
