METHOD AND APPARATUS FOR DETECTING RACH PREAMBLE ON BASIS OF PLURALITY OF ZERO-CORRELATION ZONES IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/140558

Kind Code:

A1

Abstract:

Provided are a method and an apparatus for detecting a random access channel (RACH) preamble on the basis of a plurality of zero-correlation zones (ZCZ) in a wireless communication system. A user equipment (UE) transmits a RACH preamble, generated using a combination of a plurality of sequences corresponding to a plurality of zero-correlation zones, to an evolved NodeB (eNB). The evolved NodeB (eNB) detects a plurality of peaks from the RACH preamble and transmits a random access response to the UE.
