Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may be configured to transmit two or more consecutive transmissions that may be used for demodulation reference signal (DMRS) bundling.

The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for managing uplink power control in accordance with priority-specific beta factors. An example method for wireless communication performed by a user equipment (UE) generally includes determining a value of a beta factor based on a priority level of uplink control information (UCI) to be transmitted on a physical uplink shared channel (PUSCH); and transmitting the UCI on the PUSCH with transmit power determined based, at least in part, on the value of beta factor. Another example method performed by a UE generally includes deciding, when the UE is configured to perform demodulation reference signal (DMRS) bundling across PUSCH repetitions, whether to prioritize the DMRS bundling or transmission of UCI multiplexed in one of the PUSCH repetitions; and transmitting the PUSCH repetition with the multiplexed UCI in accordance with the decision.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use dynamic power aggregation techniques to perform instantaneous transmit power adjustments in an uplink carrier aggregation configuration. For example, the UE may dynamically adjust the instantaneous transmit power with network assistance. In some cases, the base station may configure a set of power aggregation parameters to control the instantaneous transmit power behavior of the UE. The UE may adjust the instantaneous transmit power in accordance with the power aggregation parameters. In some other cases, the base station may configure the UE to report one or more parameters. Based on the report, the base station may determine a power aggregation configuration for the UE in a time interval. In some other cases, the UE may be configured to scale the instantaneous transmit power for individual component carriers in the carrier aggregation configuration.
