Document Type and Number:
WIPO Patent Application WO/2021/015565
Kind Code:
A1
Abstract:
Proposed in the present specification is a method for transmitting and receiving urgent information in a wireless communication system supporting machine type communication, and a device for same. Specifically, a method performed by a terminal may include the steps of: receiving information including a Reference Signal Received Power (RSRP) threshold value from a base station; determining a Coverage Enhancement (CE) mode on the basis of the RSRP threshold value and an RSRP measurement value; determining a Physical Random Access Channel (PRACH) resource on the basis of the CE mode; and transmitting a PRACH preamble to the base station on the basis of the PRACH resource.
