Abstract
Aspects relate to signaling relating to a non-linearity model for power amplifier circuitry of a transmitting device. The power amplifier circuitry may apply digital pre-distortion (DPD) to a signal prior to amplification and transmission of the signal. A receiving device may apply digital post-distortion (DPoD) to a signal received from the transmitting device where the DPoD is based on the non-linearity model. The transmitting device may send to the receiving device non-linearity parameters for the non-linearity model.
Claims29
A first wireless communication device, comprising:
- one or more memories that store processor-executable code;
- and
- one or more processors configured to execute the processor-executable code and cause the first wireless communication device to:
- receive, from a second wireless communication device, a capability message comprising a digital pre-distortion capability bit indicating that the second wireless communication device has a capability to compute digital pre-distortion information;
- transmit a first message to the second wireless communication device in response to the capability message, wherein the first message requests the second wireless communication device to compute the digital pre-distortion information and transmit the digital pre-distortion information to the first wireless communication device;
- and
- transmit a second message to the second wireless communication device in response to the capability message, wherein the second message comprises:
- at least one clipping level associated with a crest factor reducer of a power amplifier circuit of the first wireless communication device,
- a first kernel and first parameters associated with a digital pre-distorter of the power amplifier circuit, and
- a second kernel and second parameters associated with a power amplifier of the power amplifier circuit.
