1. A method performed by a user equipment in a wireless communication network, comprising:
obtaining a plurality of random access channel resource sets;
obtaining a measurement result of a downlink reference signal received from a wireless access network node;
selecting a first coverage recovery level from a plurality of coverage recovery levels by comparing the measurement result with a measurement threshold, the measurement threshold being configured based on a type of the user equipment, the type of the user equipment comprises a reduced capability user equipment and a full capability user equipment;
selecting, based on the first coverage recovery level, a first random access channel resource set from the plurality of random access channel resource sets;
transmitting a random access preamble on a random access channel resource in the first random access channel resource set; and
selecting, based on the first random access channel resource set, a transmit power control (TPC) command mapping table from a plurality of TPC command mapping tables, the TPC command mapping table comprising mapping information between a value of the TPC command for physical uplink shared channel (PUSCH) field and a transmit power control value as well as a number of times of repetition transmission.
