1. A method comprising:

  • detecting a synchronization signal from a base station;

    determining a synchronization detection probability based on the detection of the synchronization signal;

    estimating a coverage deficit range based on the synchronization detection probability;

    transmitting coverage deficit signaling configured to indicate the coverage deficit range estimated based on the synchronization detection probability in which a power boost is applied to transmission of the coverage deficit signaling;

    receiving and decoding a system information block (SIB) indicating a repetition signaling pattern that is selected based on the coverage deficit range and an amount of the power boost that is applied to transmission of the coverage deficit signaling; and

    transmitting an initial random access request via the repetition signaling pattern indicated by the SIB and associated with the coverage deficit range.
