Title:
A channel estimation method based on CSI*RS in a radio communications system, and a device for it
Document Type and Number:
Japanese Patent JP5912173
Kind Code:
B2
Abstract:
The present invention relates to a user equipment to perform an estimation operation in a wireless communication system. In more detail, the method includes: receiving configuration information of CSI-RSs (channel status information-reference signals) defined by a plurality of antenna ports from a base station; combining CSI-RSs defined by specific antenna ports among the plurality of antenna ports; and performing the measurement based on the combined CSI-RSs. Here, performing the measurement comprises measuring at least one of a RSRP (reference signal received power), a RSRQ (reference signal received quality) and a pathloss based on the combined CSI-RSs.
