Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. The method of claim 3,
wherein based on the received configuration information informing that PT-RS power boosting based on the number of layers for specific DM-RS port group is applied, the PT-RS received from the specific DM-RS port group is received based on power boosting level (P1) satisfying

P1=X+Y(dB)  [Equation 1]

wherein based on the received configuration information informing that PT-RS power boosting based on the number of layers for the specific DM-RS port group is not applied, the PT-RS received from the specific DM-RS port group is received based on power boosting level (P2) satisfying

P2=X(dB)  [Equation 2]

wherein X denotes a ratio of PT-RS EPRE to PDSCH EPRE per layer per RE based on a number of PT-RS ports, Y denotes the ratio of PT-RS EPRE to PDSCH EPRE per layer per RE based on the number of layers for the specific DM-RS port group.
