Certain aspects of the present disclosure relate to techniques for controlling transmission power and prioritizing transmission carriers. A method of power distribution for different physical layer channels over one or more carriers in case of power limited user equipment (UE) is proposed. Operation modes of the UE with single and multiple power amplifiers/antennas can be supported.

A method for performing wireless communication by a first device, and a device for supporting same are provided. The method may comprise: transmitting, to a second device, at least one physical sidelink control channel (PSCCH) and at least one physical sidelink shared channel (PSSCH) related to the at least one PSCCH; receiving, from the second device, at least one sidelink (SL) hybrid automatic repeat request (HARQ) feedback information through at least one physical sidelink feedback channel (PSFCH) related to the at least one PSSCH; and determining a priority value of physical uplink control channel (PUCCH) transmission for reporting the at least one SL HARQ feedback information to a base station, based on at least one priority value of the at least one SL HARQ feedback information.

In some aspects of the disclosure, a method of wireless communication includes performing a first wireless transmission using a plurality of transmission and reception points (TRPs) of a vehicle. The first wireless transmission is performed based on a first transmit power allocation among the plurality of TRPs. The method further includes, in response to the first wireless transmission, receiving one or more feedback signals indicating a receive status of the first wireless transmission at one or more devices. The method further includes performing a second wireless transmission using the plurality of TRPs based on a second transmit power allocation among the plurality of TRPs. The second transmit power allocation is determined based on at least one received signal strength of the one or more feedback signals.

A system and method for uplink multi-antenna power control in a communications system are provided. A method for user equipment operations includes determining a transmit power level for transmit antennas of the user equipment having at least two transmit antennas, and setting a power amplifier output level for each of the at least two transmit antennas in accordance with a respective transmit power level.

A user equipment (UE) configured to perform uplink power control. The UE determines that a first uplink transmission is scheduled to overlap in time with a second uplink transmission based on a look ahead window, determines a first transmission power for the first uplink transmission, determines a second transmission power for the second uplink transmission based on the first transmission power for the first uplink transmission and performs the first uplink transmission and the second uplink transmission.

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.

Reduced transmission power time intervals for wireless communications are described. A node may transmit a time interval allocation bitmap indicating a configuration of reduced transmission power time intervals. The configuration of reduced transmission power time intervals may change based on traffic load at the node.

A primary wireless access node wirelessly transmits reference signals at an initial reference signal power level. The primary wireless access node exchanges data with User Equipment (UEs) and exchanges the data with other network elements. The primary wireless access node exchanges signaling with secondary wireless access nodes. The secondary wireless access nodes exchange data between the UEs and the network elements responsive to the signaling. The primary wireless access node determines the amount of the secondary nodes and determines a new reference signal power level based on the amount of the secondary nodes. The primary wireless access node wirelessly transmits subsequent reference signals at the new reference power level.

Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining dynamic power sharing in a dual-uplink E-UTRA (Evolved Universal Terrestrial Radio Access)—new radio dual connectivity (EN-DC) network, and/or other new radio (NR) related networks. Various embodiments describe how to determine or configure respective transmission (TX) power levels for LTE and NR uplink signals in the dual-uplink EN-DC network. The NR uplink signal may or may not be transmitted based on a certain timeline threshold and/or power scaling threshold. Other embodiments may be described and claimed.
