Abstract: Aspects of frequency error detection with Physical Broadcast CHannel (PBCH) frequency hypothesis are described. For example, a method and apparatus are disclosed for frequency tracking in a user equipment (UE) may include detecting a change in frequency that exceeds a pull-in range of a frequency tracking loop (FTL) of the UE. The method and apparatus may also include identifying a tracking recovery frequency in response to the change in frequency being detected, wherein the tracking recover frequency is identified from a set of frequency hypotheses and based on decoding of the PBCH received by the UE. The method and apparatus may further include updating the FTL with the tracking recovery frequency.

Abstract: In certain aspects, a method implemented in a wireless device includes determining a specific absorption rate (SAR) distribution for a first wireless communication technology, determining a power density (PD) distribution for a second wireless communication technology, and combining the SAR distribution and the PD distribution to generate a combined RF exposure distribution. The method also includes determining at least one first maximum allowable power level and at least one second maximum allowable power level for a future time slot based on the combined RF exposure distribution, setting at least one transmission power limit for a first transmitter in the future time slot based on the at least one first maximum allowable power level, and setting at least one transmission power limit for a second transmitter in the future time slot based on the at least one second maximum allowable power level.

Abstract: In order to maintain conformance with exposure limits, in band measurements may be performed. A method, a computer-readable medium, and an apparatus may be provided for wireless communication at a user equipment. The apparatus receives an indication of a cell specific resource, e.g., a cell specific resource available for MPE measurement. The apparatus then performs a measurement based on the cell specific resource and determines whether to adjust a transmission characteristic of the user equipment based on whether the measurement meets a threshold. In another aspect a base station apparatus may configure a cell specific resource in which a user equipment may perform an MPE measurement and control use of the cell specific resource for the MPE measurement.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing beam switch latency using communications systems operating according to new radio (NR) technologies. For example, the method generally includes determining a latency associated with a beam switch from a source antenna array module to a target antenna array module when the target module is in a low power mode; and signaling a base station to use the determined latency after sending a command for the beam switch.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication. In some aspects, the scheduled entity detects a fluctuation in a beam strength of at least one transmit beam from a scheduling entity. The scheduled entity transmits a first message to the scheduling entity, the first message indicating at least the fluctuation in the beam strength of the at least one transmit beam from the scheduling entity.
