An uplink power control parameter configuration method, a terminal, and a network device are provided. The method includes: receiving a power control parameter set sent by a network device; determining a target parameter configuration index or a target parameter value for a first power control parameter item from the parameter set of the power control parameter item of the power control parameter set; and determining a target transmit power of an uplink channel or an uplink reference signal according to the target parameter configuration index or the target parameter value.

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.

Methods, systems, and devices for wireless communications are described that provide for a transmission of uplink control information (UCI) from a user equipment (UE) to a base station using uplink shared channel resources in the absence of other uplink shared channel data. Based in the UCI and uplink control parameters, the UE may determine an uplink power for transmission of the UCI based at least in part on a spectrum efficiency or a number of bits per resource element (BPRE) for the UCI.

A terminal includes a control unit that sets, when data transmitted on a sidelink shared channel is frequency division multiplexed with a sidelink reference signal in a symbol to which the sidelink shared channel is mapped, a first value of a transmit power for transmitting the reference signal to a same value as or a different value from a second value of a transmit power for transmitting the data; and a transmitting unit that transmits the reference signal and the data, wherein the transmitting unit applies the first value of the transmit power to the reference signal and applies the second value of the transmit power to the data.

A Power Headroom Report (PHR) reporting method, a PHR receiving method, a terminal, and a network device are provided. The method includes: reporting a PHR in a case that a preset reporting trigger condition is satisfied. The PHR includes a Power Headroom (PH) of a network node. The network node includes a neighboring network node, or a local network node and a neighboring network node.

The method includes measuring a first reference signal and determining a pathloss of the first reference signal; determining a pathloss of the uplink transmission according to a type of the uplink transmission, an association relationship between the uplink transmission and the first reference signal, and the pathloss of the first reference signal; determining an power adjustment amount of the uplink transmission; and determining the transmission power of the uplink transmission according to at least one of the pathloss of the uplink transmission or the power adjustment amount of the uplink transmission.

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.

A first user equipment (UE) is configured to perform power control for a sidelink (SL) feedback. The first UE is configured to select a communication resource for sending a feedback message over a SL to a second UE, and select a power level for sending the feedback message. The power level is selected based on the communication resource.
