Abstract
The present specification proposes a method for transmitting and receiving CSI in a wireless communication system, and a device therefor. The method performed by a terminal can comprise the steps of: receiving information relating to a CSI-RS resource set, wherein the information relating to the CSI-RS resource set comprises information relating to a resource pair, and the resource pair comprises a first channel measurement resource (CMR) and a second CMR configured in the same slot as the first CMR; receiving at least one CSI-RS on the basis of the first CMR and second CMR; and transmitting CSI on the basis of the at least one CSI-RS.
Claims13
A method of transmitting channel state information (CSI) in a wireless communication system, the method performed by a user equipment (UE) comprising:
- receiving information on CSI-reference signal (RS) resource set, the information on the CSI-RS resource set including information on a resource pair, the resource pair including a first channel measurement resource (CMR) and a second CMR set in the same slot as that of the first CMR,
- receiving at least one CSI-RS based on the first CMR and the second CMR;
- and
- transmitting the CSI based on the at least one CSI-RS,
- wherein the first CMR is set as a first quasi co-location (QCL)-TypeD RS and the second CMR is set as a second QCL-TypeD RS,
- wherein the first CMR is received based on a first beam for reception of the first QCL-TypeD RS and the second CMR is received based on a second beam for reception of the second QCL-TypeD RS,
- wherein a third QCL-TypeD RS corresponds to an RS different from the first QCL-TypeD RS and the second QCL-TypeD RS, and a resource, a channel, or a signal set as the third QCL-TypeD RS is not received in the same time domain as that of the first CMR or the second CMR.
A user equipment (UE) configured to transmit channel state information (CSI) in a wireless communication system, the UE comprising:
- at least one transceiver;
- at least one processor;
- and at least one memory operatively coupled to the at least one processor and configured to store instructions for performing operations based on being executed by the at least one processor,
- wherein the operations include:
- receiving information on CSI-reference signal (RS) resource set, the information on the CSI-RS resource set including information on a resource pair, the resource pair including a first channel measurement resource (CMR) and a second CMR set in the same slot as that of the first CMR;
- receiving at least one CSI-RS based on the first CMR and the second CMR;
- and
- transmitting the CSI based on the at least one CSI-RS,
- wherein the first CMR is set as a first quasi co-location (QCL)-TypeD RS and the second CMR is set as a second QCL-TypeD RS,
- wherein the first CMR is received based on a first beam for reception of the first QCL-TypeD RS and the second CMR is received based on a second beam for reception of the second QCL-TypeD RS,
- wherein a third QCL-TypeD RS corresponds to an RS different from the first QCL-TypeD RS and the second QCL-TypeD RS, and a resource, a channel, or a signal set as the third QCL-TypeD RS is not received in the same time domain as that of the first CMR or the second CMR.
A method of receiving channel state information (CSI) in a wireless communication system, the method performed by a base station (BS) comprising:
- transmitting, to a user equipment (UE), information on CSI-reference signal (RS) resource set, the information on the CSI-RS resource set including information on a resource pair, the resource pair including a first channel measurement resource (CMR) and a second CMR set in the same slot as that of the first CMR,
- transmitting, to the UE, at least one CSI-RS based on the first CMR and the second CMR;
- and
- receiving, from the UE, the CSI based on the at least one CSI-RS,
- wherein the first CMR is set as a first quasi co-location (QCL)-TypeD RS and the second CMR is set as a second QCL-TypeD RS,
- wherein the first CMR is transmitted based on a first beam for reception of the first QCL-TypeD RS and the second CMR is transmitted based on a second beam for reception of the second QCL-TypeD RS,
- wherein a third QCL-TypeD RS corresponds to an RS different from the first QCL-TypeD RS and the second QCL-TypeD RS, and a resource, a channel, or a signal set as the third QCL-TypeD RS is not received in the same time domain as that of the first CMR or the second CMR.
