METHOD FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR - A simplified explanation of the abstract
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.
