Abstract:
The present invention provides an MTC UE random access method and device. The method comprises: receiving indication information sent by a network side, the indication information being used for indicating at least one coverage enhancement level (CE LEVEL) and a physical random access channel (PRACH) resource corresponding thereto; selecting one CE LEVEL from a CE LEVEL of an MTC UE and the CE LEVEL indicated by the network side, and determining a PRACH resource corresponding to the CE LEVEL; and carrying out random access on the PRACH resource corresponding to the selected CE LEVEL. The present invention provides a mechanism of how to select a PRACH resource when a network side triggers an MTC UE to initiate a contention-free random access (CFRA) process.
