Method for measuring and reporting CSI-RS in wireless communication system, and apparatus for supporting same

摘要

Provided is a method for measuring and reporting a channel state information-reference signal (CSI-RS) by a terminal in a wireless communication system. The method involves acquiring, from a network, a measurement configuration for measuring radio resource monitoring, the measurement configuration including information for requesting a CSI-RS measurement report, performing a CSI-RS measurement based on the measurement configuration in order to acquire a CSI-RS measurement result, evaluating whether or not a measurement result report condition has been satisfied based on the measurement configuration, and, if the measurement result report condition has been satisfied, transmitting a measurement report message to the network. The measurement report message includes the CSI-RS measurement result.

主权项

1. A method for measuring a channel state information-reference signal (CSI-RS) and reporting a measurement result by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a network, a Coordinated Multi-Point transmission and reception (CoMP) configuration including at least one of a CoMP measurement set (CoMP set) and a CoMP resource management (CRM) set; acquiring, from the network, a radio resource monitoring (RRM) measurement configuration including a request of CSI-RS measurement report for CoMP, wherein the request of CSI-RS measurement report includes information on a predetermined number of CSI-RS measurement results in a measurement report, and a CSI-RS set identifier to indicate whether a measurement target CSI-RS set is the CoMP set or the CRM set; performing a CSI-RS measurement for the CoMP set or the CRM set based on the request of CSIR-RS measurement report to acquire a plurality of CSI-RS measurement results; evaluating whether or not a measurement result report condition has been satisfied based on the request of CSI-RS measurement report; and transmitting, to the network, a measurement report including the predetermined number of CSI-RS measurement results having a high quality among the plurality of CSI-RS measurement results when the measurement result report condition has been satisfied.
