Abstract: Wireless communications systems and methods related to signaling of direct current (DC) locations of user equipment devices (UEs) in a new radio (NR) network are provided. A wireless communication device receives, from a base station, at least one of a carrier aggregation (CA) configuration or a bandwidth part (BWP) configuration. The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.

Abstract: Aspects of the present disclosure provide apparatus and techniques for specific absorption rate (SAR) control for user equipments (UEs) (e.g., high-power UEs). A method for wireless communications by a UE is provided. The method generally includes determining a time division duplexing (TDD) subframe configuration defining a first number of uplink subframes and a second number downlink subframes and adjusting a transmit power level of the UE based on the TDD subframe configuration. Another method generally includes estimating SAR of the UE for a time window and taking one or more actions to reduce a number of uplink transmissions for the UE in order to achieve a target SAR for the time window.

Abstract: A user equipment (UE) includes a transmit chain that includes multiple radio frequency transmitters, multiple power amplifiers and a front end (FE) through which signals are transmitted. To achieve a high power UE solution, aspects of the disclosure selectively combine two or more power amplifier outputs based on an expected power output of the UE. To synchronously combine the outputs, an output feedback signal from a feedback receiver is used to adjust a delay and a phase of one or more signals associated with the power amplifiers.

Abstract: Certain aspects relate to controlling a transmit power of a user equipment (UE) in a wireless communication network. The UE may determine a location of the UE, and identify, from set of transmit power reduction settings stored at the UE, a power reduction indicator corresponding to the location and to a frequency range of an uplink transmission. Further, the aspects include the UE transmitting a first uplink transmission in the frequency range at a first transmit power controlled based on the power reduction indicator when the power reduction indicator is found. In another aspect, the UE transmits a second uplink transmission in the frequency range at a second transmit power controlled based on a network-signaled power reduction value when the power reduction indicator corresponding to the location is not found at the UE.

Abstract translation: 某些方面涉及在无线通信网络中控制用户设备（UE）的发射功率。 UE可以确定UE的位置，并且从存储在UE处的发射功率降低设置的集合中识别对应于上行链路传输的位置和频率范围的功率降低指示符。 此外，这些方面包括当发现功率降低指示符时，UE在基于功率降低指示符控制的第一发射功率的频率范围内发射第一上行链路传输。 在另一方面，当在UE处没有找到对应于该位置的功率降低指示符时，UE在基于网络信号功率降低值的第二发射功率的频率范围内发射第二上行链路传输。
