Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a multi-panel uplink transmission is to be performed by the UE, the multi-panel uplink transmission using at least a first transmit panel and a second transmit panel of the UE. The UE may identify a priority order for performing uplink transmissions of the multi-panel uplink transmission from the UE, the priority order including priority levels associated with the first transmit panel and the second transmit panel. The UE may identify an available transmit power for the multi-panel uplink transmission. The UE may perform, according to the priority order, the multi-panel uplink transmission using at least the first transmit panel at a first transmit power and the second transmit panel at a second transmit power, the first transmit power and the second transmit power based at least in part on the available transmit power.

The present disclosure provides a terminal capable of efficiently transmitting data of different services. In this terminal (200), a controller (209) determines a transmission operation of a first transmission, corresponding to a first service, and a second transmission, corresponding to a second service, based on the first transmission and a setting of a reference signal included in the second transmission. A transmitter (216) transmits an uplink signal including at least a signal of the first transmission based on the determined transmission operation.

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.

A UE may calculate an allocation of a transmission power for a first uplink transmission on a first uplink channel and at least one second uplink transmission on at least one second uplink channel, the transmission power being allocated in each symbol of a plurality of symbols in a slot. The UE may detect a transmission power change in the allocation of the transmission power in the slot for at least one of the first uplink transmission or the at least one second uplink transmission. The UE may determine whether to adjust the allocation of the transmission power for the at least one of the first uplink transmission or the at least one second uplink transmission to eliminate the transmission power change in the slot for the at least one of the first uplink transmission or the at least one second uplink transmission.

The present application provides a power allocation method and device of an Internet of Vehicles system, wherein a multi-carrier technology is adopted for a side link of the internet of vehicles system, and the method comprises: allocating power for a data transmission of a sidelink according to a preconfigured priority criterion.

A method by which a first device (100) performs sidelink transmission is provided. The method can comprise the steps of: determining a priority of a first carrier including a plurality of BWPs; allocating transmission power for the first carrier on the basis of the priority; and performing sidelink transmission through the plurality of BWPs on the basis of the transmission power.

A terminal including: a transmission unit that transmits a first message and a second message used in a 2-step random access procedure, the first message being transmitted via a physical random access channel and the second message transmitted via a physical uplink shared channel; and a control unit that determines a power control to be applied to the first message and the second message, according to a control based on a prioritization rule of power allocation applied to the first message or the second message, wherein the transmission unit retransmits the first message and the second message by applying the determined power control to the first message and the second message.

A user equipment (UE) may obtain high-priority data (e.g., low latency data) to be transmitted to a base station. In some scenarios, the base station may be transmitting downlink transmissions to the UE or to a different UE, or may be receiving uplink transmissions from the UE or from the different UE. The described aspects enable the UE to timely transmit the high-priority data in these scenarios. In one example, the described aspects enable the UE to transmit, to the base station, while the base station performs one or more scheduled downlink transmissions to the UE or to the different UE, at least one of the high-priority data via a first uplink beam from a set of uplink beams for unscheduled uplink transmissions or an unscheduled data indication indicating that the high-priority data is to be transmitted without an uplink grant.

Apparatuses, methods, and systems are disclosed for transmission power control. One method includes receiving a first configuration indicating a plurality of bandwidth parts on a first serving cell and configuration information corresponding to the plurality of bandwidth parts. The configuration information comprises an open-loop power control configuration, a closed loop power control configuration, or a combination thereof corresponding to each bandwidth part of the plurality of bandwidth parts. The method comprises receiving scheduling information for a first uplink transmission on a first bandwidth part of the plurality of bandwidth parts. The method comprises determining a first transmission power for the first uplink transmission based on the configuration information and the scheduling information. The method comprises performing the first uplink transmission with the first transmission power.

The invention relates to methods for adjusting the transmit power utilized by a mobile terminal for uplink transmissions, and to methods for adjusting the transmit power used by a mobile terminal for one or more RACH procedures. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for adjusting the transmit power of uplink transmissions on uplink component carriers, the invention suggests introducing a power scaling for uplink PRACH transmissions performing RACH procedures on an uplink component carrier. The power scaling is proposed on the basis of a prioritization among multiple uplink transmissions or on the basis of the uplink component carriers on which RACH procedures are performed.
