A method, performed by a wireless device in a wireless network, the method comprising: - receiving Random Access Channel, RACH, physical resource configuration information, comprising: - an indication of a first RACH configuration for a single random access attempt, the first RACH configuration having a first random access preamble and a first pre-determined number of repetitions; and - an indication of a second RACH configuration for a retry random access attempt, the second RACH configuration having a second random access preamble, different from the first random access preamble, and a second pre-determined number of repetitions, different from the first pre-determined number of repetitions; - selecting a first Random Access Channel, RACH, resource associated with the first RACH configuration for a single random access attempt; - determining a first random access message transmission power based on the first pre-determined number of random access message repetitions of the first RACH configuration; - transmitting, using the selected first RACH resource for the single random access attempt, a random access message with the first preamble, the first pre-determined number of repetitions and the first transmission power; - monitoring the Random Access Response window for one or more responses to the single random access attempt; and - when the single random access attempt fails, selecting a second RACH resource associated with the second RACH configuration for a retry random access attempt (S16b), determining a second transmission power for the retry message based on the second pre-determined number of random access message repetitions, and transmitting a retry random access message with the second preamble, the second pre-determined number of repetitions and the second transmission power. - receiving Random Access Channel, RACH, physical resource configuration information, comprising: - an indication of a first RACH configuration for a single random access attempt, the first RACH configuration having a first random access preamble and a first pre-determined number of repetitions; and - an indication of a second RACH configuration for a retry random access attempt, the second RACH configuration having a second random access preamble, different from the first random access preamble, and a second pre-determined number of repetitions, different from the first pre-determined number of repetitions; - an indication of a first RACH configuration for a single random access attempt, the first RACH configuration having a first random access preamble and a first pre-determined number of repetitions; and - an indication of a second RACH configuration for a retry random access attempt, the second RACH configuration having a second random access preamble, different from the first random access preamble, and a second pre-determined number of repetitions, different from the first pre-determined number of repetitions; - selecting a first Random Access Channel, RACH, resource associated with the first RACH configuration for a single random access attempt; - determining a first random access message transmission power based on the first pre-determined number of random access message repetitions of the first RACH configuration; - transmitting, using the selected first RACH resource for the single random access attempt, a random access message with the first preamble, the first pre-determined number of repetitions and the first transmission power; - monitoring the Random Access Response window for one or more responses to the single random access attempt; and - when the single random access attempt fails, selecting a second RACH resource associated with the second RACH configuration for a retry random access attempt (S16b), determining a second transmission power for the retry message based on the second pre-determined number of random access message repetitions, and transmitting a retry random access message with the second preamble, the second pre-determined number of repetitions and the second transmission power.
