`ABSTRACT
`The present disclosure relates to a communication method
`
`
`
`
`
`and system for converging a 5th-generation (5G) communi­
`
`
`
`cation system for supporting higher data rates beyond a
`
`
`4th-generation (4G) system with a technology for internet of
`Related U.S. Application Data
`
`
`
`
`things (IoT). The present disclosure may be applied to
`(60)Provisional application No. 62/301,016, filed on Feb.
`
`
`
`
`
`
`intelligent services based on the 5G communication tech­
`
`
`
`29, 2016, provisional application No. 62/334, 706,
`
`nology and the IoT-related technology, such as smart home,
`filed on May 11, 2016.
`
`
`smart building, smart city, smart car, connected car, health
`
`

`(2006.01)
`
`
`
`a user equipment (UE) in a wireless communication system
`(2009.01)
`
`
`is provided. The method includes receiving, from a base
`H04W 74108
`
`
`
`station (BS), first type SI associated with SI which is
`(Continued)
`
`
`
`
`essential for communication with the BS, transmitting, to the
`(52)U.S. Cl.
`
`
`
`BS, a physical random access channel (PRACH) preamble
`CPC ......... H04W 7410833 (2013.01); H04W 4106
`
`
`
`
`
`
`based on the first type SI, receiving, from the BS, a random
`
`
`(2013.01); H04W 48112 (2013.01);
`
`
`
`access response (RAR) message, and receiving, from the
`(Continued)
`
`
`
`
`BS, second type SI associated with at least one SI which the
`
