Document Type and Number:
WIPO Patent Application WO/2019/139407
Kind Code:
A1
Abstract:
The present application provides a method for determining a random access resource by a terminal in a wireless communication system, the method comprising: receiving, from a base station, configuration information corresponding to a synchronization signal block(SSB) including a SSB index, a random access preamble index and a random access channel mask index; determining a random access resource based on the SSB index and the random access channel mask index; determining a random access preamble based on the random access preamble index; and transmitting, to the base station, the random access preamble on the random access resource.
