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 receiving a CSI-RS configuration from a network, the CSI-RS configuration including information indicating a plurality of CSI-RS resources that is an object to be measured, measuring the plurality of CSI-RS resources in order to acquire a plurality of CSI-RS measurement results, determining whether or not to report the CSI-RS measurement results, and transmitting a measurement report message to the network. The measurement report message includes a specific number of CSI-RS measurement results having a higher level of quality from among the plurality of CSI-RS measurement results. |

1. A method for measuring and reporting a channel state information-reference signal (CSI-RS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a CSI-RS configuration from a network, the CSI-RS configuration including information indicating a plurality of CSI-RS resources which is an object to be measured; measuring the plurality of CSI-RS resources in order to acquire a plurality of CSI-RS measurement results; determining whether a specific number of CSI-RS resources associated with a specific number of CSI-RS measurement results is updated; and transmitting a measurement report message to the network when the specific number of the CSI-RS resources is updated, wherein the measurement report message includes the specific number of CSI-RS measurement results, a specific number of CSI-RS IDs and a report indicator, wherein the specific number of CSI-RS measurement results has a higher level of quality from among the plurality of CSI-RS measurement results, wherein the specific number of CSI-RS IDs identifies the specific number of CSI-RS resources associated with the specific number of CSI-RS measurement results, wherein the report indicator indicates whether the specific number of CSI-RS measurement results is updated, and wherein the specific number of CSI-RS resources is updated when the specific number of CSI-RS IDs for the specific number of CSI-RS resources is different from a specific number of CSI-RS IDs which is previously transmitted. |
