A CSI-RS resource assignment method and a system in a LTE-ADVANCE system

Title:

A CSI-RS resource assignment method and a system in a LTE-ADVANCE system

Document Type and Number:

Japanese Patent JP6105014

Kind Code:

B2

Abstract:

Systems and methods for the configuration of channel state information reference signals (CSI-RS) are disclosed. The systems and methods include providing user equipment with the locations of CSI-RS reuse information. Several encoding patterns and exemplary methodology for both the identification of the CSI-RS resource element locations are provided in exemplary embodiments. In addition, exemplary embodiments provide muting methods and systems for a physical downlink shared channel resource elements.
