Various aspects of the present disclosure generally relate to wireless communication. A wireless communication device may have an apparatus that aligns the non-linearity between transmit chains of the wireless communication device that are driven by the same digital port. The apparatus may adjust an amplification power out or an amplification saturated power to adjust a ratio between the amplification saturated power and the amplification power out for one or more transmit chains of the wireless communication device. The apparatus may adjust the ratios of transmit chains to align the ratios of the transmit chains for more consistent management of non-linear characteristics of the chain components. Numerous other aspects are described.

A wireless transceiver apparatus includes a power detector, an analog signal receiving circuit at wireless signal reception side, and a processing circuit. The power detector is configured at wireless signal transmission side and used for detecting power of a power amplifier on a transmitting path of wireless signal transmission side. The analog signal receiving circuit is couple to the power detector and used for receiving a wireless signal form an antenna. Under signal reception mode, the analog signal receiving circuit transmits the received wireless signal to the processing circuit. Under interference detection mode, the analog signal receiving circuit transfers the received wireless signal (as interference) to the power detector, and the power detector is used for detecting the power of wireless signal to measure an interference power value and transmit the value to the processing circuit.

The present document relates to a method for transmitting and receiving a signal by a user equipment in a wireless communication system, and discloses the method for transmitting and receiving a signal, comprising the steps of: receiving a first reference signal from a base station; receiving a second reference signal from the base station; measuring power of each of the received first reference signal and the received second reference signal; and comparing the sizes of the measured power of the first reference signal and the measured power of the second reference signal, wherein the first reference signal is received in a half-duplex (HD) transmission mode, the second reference signal is received in a full-duplex (FD) transmission mode, and an FD gain value of the FD transmission mode is changed on the basis of a result of the comparing.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a dual-connectivity (DC) configuration, and may measure signals from more than one radio access technology (RAT). The UE may receive a first signal power for a first RAT and a second signal power for a second RAT. The UE may determine a common gain state for the first RAT and the second RAT based on the first signal power and the second signal power. The UE may then apply the common gain state to a first receiver chain within the UE for the first RAT and to a second receiver chain within the UE for the second RAT, where the first receiver chain and the second receiver chain share at least one shared low noise amplifier (LNA).
