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

摘要

In accordance with various aspect of the present disclosure, apparatus may transmit a first data resource element for a first UE on a base layer. The first UE is unconfigured for NOMA communication. The apparatus may also transmits data for a second UE on an enhancement layer. The second UE is configured for NOMA communication. Additionally, the base layer is overlayed with the enhancement layer. The reference signal may include a cell specific reference signal. The apparatus may be further configured to receive a traffic power ratio for the second UE to be followed by the second UE when the second UE is a base layer UE in a NOMA communication.

1. A method of Non-Orthogonal Multiple Access (NOMA) communications at a base station, the method comprising:
transmitting a first data resource element for a first User Equipment (UE) on a base layer, the first UE unconfigured for NOMA communication; transmitting data for a second UE on an enhancement layer, the second UE configured for NOMA communication, wherein the base layer is overlayed with the enhancement layer; and transmitting a reference signal.
