Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

Abstract: A user equipment (UE) may simulate transmissions received from a BS to perform on-device testing of the UE. For example, the UE may be configured to loopback uplink data from the UL data path and input the uplink data as simulated downlink data for processing in the DL data path. The uplink data may include data related to a video call or network diagnostics. The user application data generated by the application and proceeding through the UL data path may be used to validate the DL data path. Downlink control information (DCI) may be determined by the UE and provided to the DL data path to accompany the uplink data. The DCI may include simulated uplink grants and/or simulated downlink scheduling assignments. The simulated downlink scheduling assignments may be determined based on availability of the uplink data in the UE's memory.

Abstract: A method of wireless communication includes determining an operating parameter of a mobile device. The method also includes dynamically setting a hysteresis for a gain state of a power amplifier (PA) based at least in part on the determined operating parameter. The hysteresis may include a power level hysteresis and a temporal hysteresis
