Classification: CPC H | IPC H

Claim 6:
7. The method of claim 3, wherein based on the received configuration information informing that the PT-RS power boosting based on the number of layers is applied to a specific DM-RS port group, the PT-RS received from the specific DM-RS port group is received at a power boosting level (P3) satisfying

P3=min(PMAX,X+Y)(dB),  [Equation 3]

wherein based on the received configuration information informing that the PT-RS power boosting based on the number of layers is not applied to the specific DM-RS port group, the PT-RS received from the specific DM-RS port group is received at a power boosting level (P4) satisfying

P4=min(PMAX,X)(dB), and  [Equation 4]

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 a ratio of PT-RS EPRE to PDSCH EPRE per layer per RE based on a number of layers for the specific DM-RS port group, and PMAX denotes a power boosting threshold level configured by higher layer signaling.
