Abstract
The present disclosure relates to downlink control information (DCI) enhancements for non-orthogonal multiple access. For example, the disclosure presents a method and an apparatus for wireless communications that may include determining, at the base station, downlink control information (DCI) for a first user equipment (UE), wherein the DCI for the first UE comprises modulation order information, spatial layer information, and power ratio information of the first UE, and a precoding matrix indicator (PMI) and spatial layer information of a second UE; and transmitting the determined DCI to the first UE.
Claims30
A method of wireless communications at a base station, comprising:
- determining, at the base station, downlink control information (DCI) for a first user equipment (UE), wherein the DCI for the first UE comprises modulation order information, spatial layer information, and power ratio information of the first UE, and a precoding matrix indicator (PMI) and spatial layer information of a second UE;
- and
- transmitting the determined DCI to the first UE.
An apparatus for wireless communications at a base station, comprising:
- means for determining, at the base station, downlink control information (DCI) for a first user equipment (UE), wherein the DCI for the first UE comprises modulation order information, spatial layer information, and power ratio information of the first UE, and a precoding matrix indicator (PMI) and spatial layer information of a second UE;
- and
- means for transmitting the determined DCI to the first UE.
An apparatus for wireless communications at a base station, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- determine, at the base station, downlink control information (DCI) for a first user equipment (UE), wherein the DCI for the first UE comprises modulation order information, spatial layer information, and power ratio information of the first UE, and a precoding matrix indicator (PMI) and spatial layer information of a second UE;
- and
- transmit the determined DCI to the first UE.
A non-transitory computer-readable medium storing computer executable code for wireless communications at a base station, comprising:
- code for determining, at the base station, downlink control information (DCI) for a first user equipment (UE), wherein the DCI for the first UE comprises modulation order information, spatial layer information, and power ratio information of the first UE, and a precoding matrix indicator (PMI) and spatial layer information of a second UE;
- and
- code for transmitting the determined DCI to the first UE.
