Abstract: A method and apparatus to enhance uplink coverage is provided. Method for enhancing uplink coverage includes receiving a SIB1 and performing a random access procedure with preamble repetition in case that Reference Signal Received Power (RSRP) of downlink pathloss reference is less than at least one of one or more thresholds related to preamble repetition. The SIB1 comprises a set of parameters related to system information scheduling and a set of parameters related to uplink configuration. Random access resource indicated in the set of parameters related to system information scheduling is used in case that the random access procedure is triggered for System Information (SI) request. Random access resource indicated in the set of parameters related to uplink configuration is used in case that the random access procedure is triggered for data transmission.
