AMPLITUDE CONTROL CAPABILITY INDICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17380971 titled 'AMPLITUDE CONTROL CAPABILITY INDICATION
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications. It focuses on a user equipment (UE) transmitting control signaling to a base station, indicating its capability to apply an amplitude control procedure for beamforming and confirming that it is currently applying the procedure. The UE receives a control message scheduling the transmission of an uplink message. It generates a signal containing the uplink message using the amplitude control procedure, which adjusts the amplitudes of the signal. The UE then transmits the signal through its antenna elements. Additionally, the UE can indicate the power loss in the signal caused by the amplitude control procedure, and the base station can compensate for this power loss by using a lower order modulation and coding scheme or applying a power boost during downlink transmissions.

Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, control signaling indicating a capability of the UE to apply an amplitude control procedure to one or more antenna elements for beamforming and indicating that the UE is applying the amplitude control procedure. The UE may receive a control message scheduling transmission of an uplink message. The UE may generate a signal including the uplink message using the amplitude control procedure, which may adjust one or more amplitudes of the signal. The UE may transmit the signal via the one or more antenna elements. In some cases, UE may indicate an amount of power loss in the signal based on the amplitude control procedure, and the base station may transmit downlink transmissions using a lower order modulation and coding scheme or an applied power boost to compensate for the power loss.
