Abstract: Systems and techniques are described herein. For example, a process can include obtaining first sensor measurement data associated with a and second sensor measurement from one or more sensors. In some cases, the first measurement data can be associated with a first time and the second sensor measurement data can be associated with a second time occurring after the first time. In some aspects, the process includes determining that the first sensor measurement data and the second sensor measurement data satisfy at least one batching condition. In some examples, the process includes, based on determining that the first sensor measurement data and the second sensor measurement data satisfy the at least one batching condition, generating a sensor measurement data batch including the first sensor measurement data, the second sensor measurement data, and at least one target sensor measurement data. Ins examples the process includes outputting the sensor measurement data batch.

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: Methods, systems, and devices for wireless communications are described. Generally, Generally, a base station may send to a user equipment (UE) a configuration message, which may include an indication of one or more CSI-RS resources and one or more random access occasion indices. The UE may identify one or more random access occasions associated with the UE based on the CSI-RS resources, the random access occasion indices for the UE, and a random access occasion index reset time. The random access occasion index rest time may be based on a fixed time period. The random access occasion index reset time may be based on a number of CSI-RS resources. In some examples, the random access occasion index reset time may be based on a number of actually transmitted synchronization signal blocks (SSBs).

Abstract: Various aspects of the disclosure relate to reporting power headroom of an apparatus such as a user equipment (UE). For an apparatus that uses beamforming, the power headroom associated with the beam the apparatus is using for wireless communication (e.g., with a base station) may be lower than the power headroom associated with another beam that the apparatus could use for the wireless communication. The disclosure relates in some aspects to using one beam for wireless communication and using the power headroom for another beam for a power headroom report. In this way, the apparatus may always report its full transmit power capability.

Abstract: A user equipment (UE) may determine an amount of energy with which the UE is able to transmit in a first network. The UE may send, to a base station, information indicating the determined amount of energy. The UE may receive, from the base station, scheduling information based on the information indicating the determined amount of energy. The base station may receive, from the UE, the information indicating the amount of energy with which the UE is able to transmit in a first network. The base station may determine scheduling information based on the information indicating the amount of energy with which the UE is able to transmit in the first network, and the scheduling information may prevent the UE from exceeding a threshold amount of energy for a time period. The base station may send, to the UE, information indicating the scheduling information.

Abstract: Method and apparatus are provided for generating and reporting actual UL transmission power. In accordance with some implementation, a UE sends a first indication of power headroom to a base station. The UE may, from the base station, one or more resources allocation for a UL transmission. UE then may determine actual transmission power to be used in the UL transmission. Upon determination, the UE may the UL transmission based on the determination and send an indication of the actual transmission power to the base station.

Abstract: Techniques for providing transmission throttling for emission exposure management are described. Embodiments implement duty cycle based transmission throttling for emission exposure management. Transmission throttling implemented in accordance with embodiments drops or skips transmission of some portion of transmission blocks of a communication process, such as to drop some transmission blocks providing retransmission of data. Transmit power levels utilized with respect to each of transmission blocks transmitted may be closer to that of a transmit power control target level (e.g., meeting the TPC target level) while nevertheless meeting an emission exposure limit level. Embodiments may, for example, be implemented with respect to a hybrid automatic repeat request (HARQ) process. Other aspects and features are also claimed and described.
