Title:
METHOD AND APPARATUS FOR CONFIGURING AND DETECTING CYCLIC PREFIX LENGTH IN CELL SUPPORTING MULTIPLE SUBCARRIER SPACINGS
Document Type and Number:
WIPO Patent Application WO/2018/056767
Kind Code:
A1
Abstract:
The present embodiments relate to a method for configuring a cyclic prefix for a next generation/5G radio access network (referred to as new radio (NR)) about which 3GPP has begun discussions. According to the present embodiments, a base station configures cyclic prefix (CP) lengths for secondary numerology except for reference numerology and sets, through RRC signaling, the values of the CP lengths configured for the secondary numerology, thereby enabling a terminal to detect the CP lengths for the secondary numerology in a cell supporting mixed numerology.
