Title:
VIRTUAL CARRIER OPERATION FOR NR SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2018/028623
Kind Code:
A1
Abstract:
A narrow band operation under a larger carrier bandwidth for new radio (NR) system is proposed. The narrow band is named as a narrow virtual carrier (VC), i.e., a wider system bandwidth comprises multiple narrower virtual carriers, and virtual carrier is UE-specific. Further, a unified indication way for VC operation under different system bandwidth (BW) & subcarrier spacing is introduced. UE receives VC configuration from eNB, which comprises an offset direction, an offset value, and a VC BW. In addition, the UE receives VC ON/OFF command from the eNB to determine the activated VCs. Multiple VCs are aggregated by the UE, and the aggregating pattern is indicated by the eNB or determined by the UE.
