Title:
TRANSMITTER AND TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/159568
Kind Code:
A1
Abstract:
The present invention provides a transmitter which can suitably perform a transmission power control in a PT-RS port. In this transmitter (100), a control unit (101) determines a transmission power for transmitting a reference signal (PT-RS) for phase tracking and a data signal within a range in which the maximum transmission power for each antenna port is not exceeded. In addition, a transmission unit (105) transmits the reference signal for phase tracking and the data signal at the transmission power determined by the control unit (10).
