Abstract

A method of transmitting a reference signal by a base station in a wireless communication system is provided. The method includes: generating a plurality of reference signals for channel measurement, wherein the plurality of reference signals for channel measurement are different types; and transmitting the plurality of reference signals for channel measurement, wherein the plurality of reference signals for channel measurement are transmitted using one or more subframes as a duty cycle.

Claims10

Dependent claims

A method of receiving at least one reference signal (RS) in a wireless communication system, the method comprising:

receiving a Radio Resource Control (RRC) signal for a first type channel state information reference signal (CSI-RS) and a second type CSI-RS,
wherein the first type CSI-RS is an aperiodic RS or a periodic RS, and the second type CSI-RS is an aperiodic RS or a periodic RS,
wherein the RRC signal includes first information related to a time point to receive the first type CSI-RS when the first type CSI-RS is an aperiodic RS,
wherein the RRC signal includes second information related to a time point to receive the second type CSI-RS when the second type CSI-RS is an aperiodic RS;
receiving at least one of the first type CSI-RS and/or the second type CSI-RS based on the RRC signal,
wherein the first type CSI-RS is received based on a first radio resource including first consecutive resource blocks (RBs),
wherein the second type CSI-RS is received based on a second radio resource including second consecutive RBs;
and
performing channel estimation based on at least one of the first type CSI-RS and/or the second type CSI-RS.

6 more elements

A user equipment (UE) for receiving at least one reference signal (RS) in a wireless communication system, the apparatus comprising:

a transceiver receiving a radio signal;
and
a processor coupled to transceiver and configured for:
receiving a Radio Resource Control (RRC) signal for a first type channel state information reference signal (CSI-RS) and a second type CSI-RS,
wherein the first type CSI-RS is an aperiodic RS or a periodic RS, and the second type CSI-RS is an aperiodic RS or a periodic RS,
wherein the RRC signal includes first information related to a time point to receive the first type CSI-RS when the first type CSI-RS is an aperiodic RS,
wherein the RRC signal includes second information related to a time point to receive the second type CSI-RS when the second type CSI-RS is an aperiodic RS;
receiving at least one of the first type CSI-RS and/or the second type CSI-RS based on the RRC signal,
wherein the first type CSI-RS is received based on a first radio resource including first consecutive resource blocks (RBs),
wherein the second type CSI-RS is received based on a second radio resource including second consecutive RBs;
and
performing channel estimation based on at least one of the first type CSI-RS and/or the second type CSI-RS.
