Reference signal power boosting in a telecommunication system

A method of a base station, the method comprising:

• transmitting, to a terminal, information related to power of an uplink phase tracking reference signal (PTRS);
• and
• receiving, from the terminal, the uplink PTRS based on a factor,
• wherein a factor related to a physical uplink shared channel (PUSCH) to PTRS power ratio per layer per resource element (RE) is identified based on the information, a number of PUSCH layers, and a type of an uplink transmission,
• wherein the factor related to the PUSCH to PTRS power ratio per layer per RE is identified based on information associated with an uplink PTRS port, in case the type of the uplink transmission is one of a codebook-based partial coherent transmission, a codebook-based non-coherent transmission, and a non-codebook based transmission, and
• wherein the number of PUSCH layers is identified based on both of a number of PUSCH layers within a demodulation reference signal (DMRS) port group containing a DMRS port associated with the uplink PTRS port and a number of PUSCH layers not within the DMRS port group containing the DMRS port associated with the uplink PTRS port.

A terminal, the terminal comprising:

• a transceiver;
• and
• a controller operably connected to the transceiver, the transceiver configured to:
• receive, from a base station, information related to power of an uplink phase tracking reference signal (PTRS),
• identify a factor related to a physical uplink shared channel (PUSCH) to PTRS power ratio per layer per resource element (RE) based on the information, a number of PUSCH layers, and a type of an uplink transmission, and
• transmit, to the base station, the uplink PTRS based on the factor,
• wherein the factor related to the PUSCH to PTRS power ratio per layer per RE is identified based on information associated with an uplink PTRS port in case the type of the uplink transmission is one of a codebook-based partial coherent transmission, a codebook-based non-coherent transmission, and a non-codebook based transmission, and
• wherein the number of PUSCH layers is identified based on both of a number of PUSCH layers within a demodulation reference signal (DMRS) port group containing a DMRS port associated with the uplink PTRS port and a number of PUSCH layers not within the DMRS port group containing the DMRS port associated with the uplink PTRS port.
