    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: A method of transmitting channel quality indicator (CQI) includes obtaining CQI of each, of the plurality of sub-bands, selecting a first sub-band having the best CQI of the plurality of sub-bands, transmitting the best CQI of the first sub-band at a first transmission cycle and transmitting a difference value between the best CQI of the first sub-band and a CQI of the first sub-band at a second transmission cycle. Signalling overhead due to CQI transmission can be reduced.

    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.

    摘要: A method and apparatus for transmitting data having time diversity and data having time-frequency diversity, and a pattern generating method for the same are disclosed. The apparatus enables Tx data to have time diversity or time frequency diversity using a predetermined pattern multiplied by Tx data of a time domain or Tx data of time and frequency domains. The apparatus makes a cyclic delay diversity (CDD) scheme to have the diversity of time and frequency domains, and may acquire an additional diversity gain by a combination of the above-mentioned methods.
