Method for measuring channel using tracking reference signal in wireless communication system and device using same

摘要

A method for measuring a channel in a wireless communication system is provided. A terminal receives a first reference signal from a primary cell. The terminal receives a second reference signal from a secondary cell corresponding to the primary cell. The terminal measures a channel for the secondary cell on the basis of the second reference signal. A subframe in which the second reference signal is received is signaled from the primary cell.

1. A method for measuring a channel in a wireless communication system, the method comprising:
receiving a first reference signal from a primary cell; receiving a second reference signal from a secondary cell corresponding to the primary cell; and performing channel measurement on the secondary cell based on the second reference signal, wherein a subframe in which the second reference signal is received is signaled by the primary cell, and wherein, if the subframe signaled by the primary cell is an uplink subframe or a special subframe, the second reference signal is received in a downlink subframe that is included in plural subframes prior to the uplink subframe or the special subframe and that is closest to the uplink subframe or the special subframe.
