Abstract: The present disclosure provide a method and terminal for counting preamble retransmission in a random access procedure. The method includes: in a random access procedure, when detecting that no Random Access Response (RAR) is received or contention resolution fails, counting a number of times of retransmission of a preamble and/or a number of times of power ramping of transmission of the preamble according to a configured counter/counters.
