Abstract
Techniques for performing path loss (PL) compensation in coordinated multipoint (CoMP) systems are provided. A method for wireless communications by a user equipment (UE) is provided. The method generally includes selecting from a plurality of transmission points involved in uplink (UL) coordinated multipoint (CoMP) operations with the UE a transmission point to associate with for path loss (PL) compensation and adjusting power of one or more transmissions based on path loss measured based on the selected transmission point.
