  • Patent number: 11178696
    Abstract: According to the present invention, transmission power of a preamble for a random access process is determined on the basis of a preamble transmission counter and a downlink path loss estimate value in a wireless communication system. The preamble transmission counter is calculated by using the number of preamble transmissions performed by a user equipment for the random access process, regardless of a random access channel resource. The downlink path loss estimate value is calculated for a synchronization signal linked to the random access channel resource used in transmitting a corresponding preamble. Other downlink path loss estimate values can be calculated for other synchronization signals.
