摘要： Embodiments of the present invention relate to a wireless communication system, and more particularly, to a technology for allocating a Channel State Information-Reference Signal (CSI-RS) in a wireless communication system. Embodiments of the present invention provides an apparatus and method for allocating CSI-RSs to resource areas, in which, under the condition of a subframe in which the CP is an extended CP, and the duplex scheme is TDD, if CSI-RSs for maximum 8 antenna ports are allocated, the CSI-RSs are allocated to the 8th and 9th symbols (symbol No. l=7 and 8), wherein each CSI-RS for every two antenna ports is allocated to the same RE while being discriminated from each other by an orthogonal code and neighbor CSI-RS allocated REs in the frequency axis are spaced by an interval of three REs.

摘要： A base station includes: an area information generation unit which generates information for a determined second area by determining an additional assignment of the second area different from a first area to a component carrier (CC) of the first area having a bandwidth smaller than a bandwidth of a maximum assignable CC; a mapping control unit which controls an assignment of a reference signal to a frequency band including the first and second areas by generating the reference signal for channel estimation in the first and second areas; a signal generation unit which generates the information for the second area and the reference signal as a wireless signal; and a transmission unit for transmitting the generated wireless signal and is characterized by transmitting data to a user terminal and receiving the data from the user terminal by assigning the resources to the first and second areas.
