Abstract: Provided is a random access method, including: a broadcast signal sent by a base station on a non-SUL carrier is received, the broadcast signal is parsed to obtain a first RSRP threshold and a second RSRP threshold, the first RSRP threshold being an RSRP limit value at which an MsgA PRACH signal is received and parsed on the non-SUL carrier to reach a target block error rate, and the second RSRP threshold being an RSRP limit value at which an MsgA PUSCH signal is received and parsed on the non-SUL carrier to reach a target block error rate; an RSRP of the broadcast signal on the non-SUL carrier is measured to obtain a measured RSRP; and carriers for sending the MsgA PUSCH signal and the MsgA PRACH signal are determined separately according to a numerical relation between the measured RSRP and the first RSRP threshold and the second RSRP threshold.
