Abstract:
Systems, methods, apparatuses, and computer program products for determining reference signal (RS) resources for pathloss calculations for multi-transmission reception point (TRP) uplink (UL) schemes are provided. A method may include detecting by a user equipment that a pathloss reference reference-signal is not provided for multi-transmission reception point uplink repetition or transmission scheme. The method may also include determining a first reference signal resource and a second reference signal resource as a result of the detecting. The method may further include calculating two pathloss values using the first reference signal resource and the second reference signal resource. Further, the method may include performing separate uplink power control for repetitions or transmissions toward different transmission reception points according to the two pathloss values.
