A method for ensuring parallel data random access, characterized by comprising: when a random access sequence transmitted by a user equipment through a physical random access channel, PRACH is sent in a same subframe with other uplink transmission, and when power is limited, controlling a priority of power transmission of the PRACH and a priority of power transmission of an uplink channel comprising a physical uplink control channel, PUCCH, and a physical uplink shared channel, PUSCH, over which the other uplink transmission is performed according to the following: controlling a priority of power transmission of a PUSCH transmission which does not comprise uplink control information, UCI, to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PRACH, and the priority of power transmission of the PRACH to be lower than a priority of power transmission of the PUCCH; or controlling a priority of power transmission of a PUSCH transmission which does not comprise UCI to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PUCCH, and the priority of power transmission of the PUCCH to be lower than a priority of power transmission of the PRACH; or controlling a priority of power transmission of a PUSCH transmission which does not comprise UCI to be lower than a priority of power transmission of the PRACH, the priority of power transmission of the PRACH to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, and the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PUCCH. when a random access sequence transmitted by a user equipment through a physical random access channel, PRACH is sent in a same subframe with other uplink transmission, and when power is limited, controlling a priority of power transmission of the PRACH and a priority of power transmission of an uplink channel comprising a physical uplink control channel, PUCCH, and a physical uplink shared channel, PUSCH, over which the other uplink transmission is performed according to the following: controlling a priority of power transmission of a PUSCH transmission which does not comprise uplink control information, UCI, to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PRACH, and the priority of power transmission of the PRACH to be lower than a priority of power transmission of the PUCCH; or controlling a priority of power transmission of a PUSCH transmission which does not comprise UCI to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PUCCH, and the priority of power transmission of the PUCCH to be lower than a priority of power transmission of the PRACH; or controlling a priority of power transmission of a PUSCH transmission which does not comprise UCI to be lower than a priority of power transmission of the PRACH, the priority of power transmission of the PRACH to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, and the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PUCCH. controlling a priority of power transmission of a PUSCH transmission which does not comprise uplink control information, UCI, to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PRACH, and the priority of power transmission of the PRACH to be lower than a priority of power transmission of the PUCCH; or controlling a priority of power transmission of a PUSCH transmission which does not comprise UCI to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PUCCH, and the priority of power transmission of the PUCCH to be lower than a priority of power transmission of the PRACH; or controlling a priority of power transmission of a PUSCH transmission which does not comprise UCI to be lower than a priority of power transmission of the PRACH, the priority of power transmission of the PRACH to be lower than a priority of power transmission of a PUSCH transmission which comprises the UCI, and the priority of power transmission of the PUSCH transmission which comprises the UCI to be lower than a priority of power transmission of the PUCCH.
