Abstract
A random access power control apparatus and method and a communication system. The random access power control apparatus includes: a first calculating unit configured to, by using a pathloss estimated based on an synchronization signal/physical broadcast channel block and/or a channel state information reference signal (CSI-RS) currently selected by a UE, calculate transmission power used by the UE in transmitting random access preambles. Hence, the UE may be adapted to UE random access procedures in such complex scenarios as multiple beams.
