APPARATUS AND METHOD FOR CONFIGURING AND DETECTING A LENGTH OF A CYCLIC PREFIX IN A CELL SUPPORTING A PLURALITY OF SUBCARRIER SPACING

摘要

The present embodiments relate to a method for setting a cyclic prefix for a next generation/5G radio access network (NR [New Radio]), which has been discussed in 3GPP. According to the present embodiments, the base station sets the length of the cyclic prefix for the secondary numerology other than the reference numerology and sets the secondary numerology to the secondary numerology. By setting the CP length value set for RRC signaling, the UE can detect the CP length for the secondary numerology in a cell supporting mixed numerology.
