This abstract first appeared for US patent application 16088050 titled 'METHOD FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR

==Simplified Explanation==

The present invention is a method for a terminal in a wireless communication system to receive a channel state information-reference signal (CSI-RS). The method includes the following steps:

* Receiving CSI-RS configuration information from a base station, which indicates the mapping of the CSI-RS.
* Receiving the CSI-RS from the base station, which is transmitted through multiple antenna ports, based on the received CSI-RS configuration information.

In the case where the CSI-RS configuration is a 32-port configuration that aggregates four 8-port configurations, a code division multiplexing (CDM)-8 pattern is applied to the 32-port configuration. The CDM-8 pattern consists of eight orthogonal weight vectors. This pattern is applied to one resource element (RE)-pair selected for each of the aggregated 8-port configurations.

Potential applications of this technology:

* Wireless communication systems
* Terminal devices in wireless networks

Problems solved by this technology:

* Efficient reception of CSI-RS by terminal devices
* Improved mapping and configuration of CSI-RS

Benefits of this technology:

* Enhanced performance and accuracy of channel state information
* Improved overall efficiency and reliability of wireless communication systems


==Original Abstract Submitted==

An aspect of the present invention provides a method for receiving a channel state information-reference signal (CSI-RS) by a terminal in a wireless communication system, the method comprising the steps of: receiving, from a base station, CSI-RS configuration information indicating a CSI-RS configuration about mapping of the CSI-RS; and receiving, from the base station, the CSI-RS which is transmitted through multiple antenna ports, on the basis of the received CSI-RS configuration information, wherein, when the CSI-RS configuration is a 32-port CSI-RS configuration into which four 8-port CSI-RS configurations are aggregated, a code division multiplexing (CDM)-8 pattern, in which the number of orthogonal weight vectors is 8, is applied to the 32-port CSI-RS configuration, wherein the CDM-8 pattern may be applied to one resource element (RE)-pair selected for each of the aggregated 8-port CSI-RS configurations.
