Method and apparatus for cooperative transmission in multi-node system

摘要

A method of performing cooperative transmission in a multi-node system including a Base Station (BS) and a plurality of nodes controlled by the BS is provided. The method comprises: transmitting a first signal generated using a first cell identifier (ID) from the plurality of nodes; and transmitting a second signal generated using a second cell ID from at least one of the plurality of nodes, wherein the first cell ID is identical with a cell ID used by the BS, and the second cell ID is different from the first cell ID.

1. A method for transmitting a reference signal, performed by a base station, in a wireless communication system, the method comprising:
transmitting synchronization signals, wherein the synchronization signals are generated based on a first identifier; generating a reference signal; and transmitting the reference signal, wherein if no value for a second identifier has been provided by the base station, the reference signal is generated using the first identifier, or if a value for the second identifier has been provided by the based station, the reference signal a generated using the second identifier, wherein the first identifier is any one value among 504 values, and wherein the first identifier and the second identifier have a same bit size.
