Abstract
Methods, systems, and devices for wireless communications are described. A receiving device may receive a channel estimation reference signal (CHEST-RS) transmitted over a bandwidth, the CHEST-RS associated with a power amplifier (PA) configuration of a transmitting device. The receiving device may determine a channel estimation measurement associated with the PA configuration based at least in part on the CHEST-RS. The receiving device may receive a non-linear estimation reference signal (NLEST-RS) transmitted over a subset bandwidth of the bandwidth, the NLEST-RS associated with the PA configuration. The receiving device may determine a non-linear estimation measurement associated with the PA configuration based at least in part on the NLEST-RS and the CHEST-RS, the non-linear estimation measurement identifying a non-linear response of the PA configuration. The receiving device may communicate with the transmitting device based at least in part on the channel estimation measurement and the non-linear response of the PA configuration.
