Claim of US Patent No. 10,117,199

1. A method for measuring a channel by a terminal configured to operate on two or more frequency bands, each of the frequency bands being configured with a subcarrier spacing different from each other, in a wireless communication system, the method comprising:performing blind detection on a synchronization signal or a reference signal defined by each subcarrier spacing;
determining a subcarrier spacing configured for the terminal according to the detected synchronization signal or the reference signal; and
performing channel measurement using the detected synchronization signal or the reference signal,
wherein the reference signal is mapped to a resource with a resource mapping pattern defined for each subcarrier spacing, and
wherein reference signals for all subcarrier spacing are mapped to a resource with resource mapping patterns having identical density, each of the resource mapping patterns corresponding to a respective one of all the subcarrier spacing.
