REFERENCE SIGNAL AND SIGNALLING DESIGN FOR NON-ORTHOGONAL MULTIPLE ACCESS WITH LEGACY USER EQUIPMENT AS BASE LAYER

摘要

PROBLEM TO BE SOLVED: To provide improved technologies of the LTE technology applicable to other multi-access technologies and telecommunication standards corresponding to increased demand for mobile broadband access.;SOLUTION: A method comprises: transmitting 702 a first data resource element for a first UE on a base layer, the first UE unconfigured for NOMA communication; transmitting 704 data for a second UE on an enhancement layer, the second UE configured for NOMA communication; transmitting 706 a cell-specific reference signal; and optionally transmitting 708 a first UE traffic power ratio, transmitting 710 a signal to restrict the first UE to QPSK, and determining 712 enhancement layer power.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2020,JPO&INPIT
