Method and apparatus for reporting a measurement in a wireless communication system

摘要

The present invention relates to a method for reporting a measurement by a terminal, comprising the steps of: measuring the magnitude of a signal from a first transmission point; and measuring the magnitude of a signal from a second transmission point. The measurements of the magnitudes of the signals from each transmission point are performed using a channel state information reference signal.

1. A method for performing measurement reporting at a User Equipment (UE) in a wireless communication system, the method comprising:
receiving, from a serving cell, a neighboring cell list; measuring channel state information (CSI) using a first CSI-reference signal (CSI-RS) from the serving cell; reporting a result of the CSI measurement to the serving cell; measuring radio resource management (RRM) using a second CSI-RS from a neighboring cell; reporting a result of the RRM measurement to the serving cell; and transmitting a random access preamble to a neighboring cell based on an equation min{Pcmax, PRTP+PLc}, where Pcmax is maximum transmission power allowed to the UE, PRTP is preamble received target power, and PLc is pathloss determined based on a result of the RRM measurement of the second CSI-RS, wherein the first CSI-RS and the second CSI-RS belong to a specific CSI-RS configuration and are transmitted with different CSI-RS antenna port numbers of the specific CSI-RS configuration by the serving cell and the neighboring cell respectively, and wherein the serving cell and the neighboring cell are distinguished from each other by the different CSI-RS antenna port numbers, the different CSI-RS antenna port numbers being signaled by the neighbor cell list.
