Abstract
A method of transmitting a reference signal from a base station to a user equipment in a wireless communication system and apparatus therefor are disclosed. The present invention includes dividing a system band into at least one or more partial bands, configuring a time-axis high density reference signal on a high frequency partial band with reference to a center frequency of the system band, configuring a time-axis low density reference signal on a low frequency partial band with reference to the center frequency, and transmitting the configured reference signals to the user equipment.
Claims8
A method of transmitting a reference signal to a user equipment by a base station in a wireless communication system, the method comprising:
- configuring reference signals for subframes included in a system frame;
- transmitting subframe configuration information including information on the reference signals to the user equipment;
- and transmitting the configured reference signals to the user equipment, wherein the reference signals comprise a first reference signal having a time-axis high density and second reference signal having a time-axis low density,
- wherein the system frame comprises a 1st subframe type having both the first reference signal and the second reference signal and a 2nd subframe type having the second reference signal only,
- wherein, in the 1st subframe type, the first reference signal is configured on a high frequency partial band with reference to a center frequency of a system band and the second reference signal is configured on a low frequency partial band with reference to the center frequency,
- and wherein, in the 2nd subframe type, the second reference signal is configured across the system band.
A base station in a wireless communication system, the base station comprising:
- a processor for configuring reference signals for subframes included in a system frame;
- and a transmitter for transmitting subframe configuration information including information on the reference signals to the user equipment and transmitting the configured reference signals to a user equipment,
- wherein the reference signals comprise a first reference signal having a time-axis high density and a second reference signal having a time-axis low density,
- wherein the system frame comprises a 1st subframe type having both the first reference signal and the second reference signal and a 2nds subframe type having the second reference signal only,
- wherein, in the 1st subframe type, the first reference signal is configured on a high frequency partial band with reference to a center frequency of a system band and the second reference signal is configured on a low frequency partial band with reference to the center frequency,
- and wherein, in the 2nd subframe type, the second reference signal is configured across the system band.
