Abstract
Disclosed is a method for a terminal to receive a reference signal in a wireless communication system. In particular, the method comprises: receiving first information related to a reference signal configuration from a serving cell; receiving the reference signal from a neighbor cell on the basis of the first information; and obtaining second information on the timing of the reference signal on the basis of the sequence of the reference signal, wherein the reference signal is of a different type from a SS/PBCH block.
Claims5
A method for receiving a channel state information-reference signal (CSI-RS) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a serving cell, first information related to a CSI-RS configuration;
- receiving, from the serving cell, second information related to at least one synchronization signal/physical broadcast channel (SS/PBCH) block which can be transmitted among a plurality of SS/PBCH blocks;
- receiving, from a neighbor cell, the CSI-RS based on the first information;
- receiving, from the neighbor cell, a SS/PBCH block associated with the CSI-RS among the at least one SS/PBCH block;
- and
- acquiring third information related to an index of the SS/PBCH block based on a sequence of the CSI-RS,
- wherein the CSI-RS is received in the same Orthogonal Frequency Division Multiplexing (OFDM) symbol including the SS/PBCH block,
- wherein the CSI-RS is received in subcarriers different from subcarriers in which the SS/PBCH block is received, and
- wherein a periodicity of the CSI-RS is the same with a periodicity of the SS/PBCH block.
A communication apparatus for receiving a channel state information-reference signal (CSI-RS) in a wireless communication system, the communication apparatus comprising:
- a memory;
- and
- a processor connected to the memory,
- wherein the processor is configured to:
- receive, by the processor from a serving cell, first information related to a CSI-RS configuration;
- receive, by the processor from the serving cell, second information related to at least one synchronization signal/physical broadcast channel (SS/PBCH) block which can be transmitted among a plurality of SS/PBCH blocks;
- receive, by the processor from a neighbor cell, the CSI-RS based on the first information;
- receive, by the processor from the neighbor cell, a SS/PBCH block associated with the CSI-RS among the at least one SS/PBCH block;
- and
- acquire, by the processor, third information related to an index of the SS/PBCH block based on a sequence of the CSI-RS,
- wherein the CSI-RS is received, by the processor, in the same Orthogonal Frequency Division Multiplexing (OFDM) symbol including the SS/PBCH block,
- wherein the CSI-RS is received, by the processor, in subcarriers different from subcarriers in which the SS/PBCH block is received, and
- wherein a periodicity of the CSI-RS is the same with a periodicity of the SS/PBCH block.
