Apparatus and method for controlling transmission power of DMRS in new radio

Abstract:

Provided is a method of a base station for controlling the transmission power of a demodulation reference signal (DMRS) to a user equipment. The method may include determining a ratio of one or more empty resource elements to one or more DMRS resource elements over one or more DMRS symbols, determining a DMRS power boosting based on the determined ratio value, and transmitting the DMRS with power determined based on the DMRS power boosting to the user equipment.
