Disclosed are a power control method and device, a terminal, and a storage medium. The method comprises: determining a reference point corresponding to the closed-loop power control parameter of a PUSCH transmission unit i; determining a power adjustment amount corresponding to the closed-loop power control parameter of the transmission unit i; determining the closed-loop power control parameter of the transmission unit i according to the reference point and the power adjustment amount; and determining the transmit power of uplink data to be transmitted at the transmission unit i according to the closed-loop power control parameter of the transmission unit i.

A method for uplink data transmission. The method is applicable to user equipment (UE), and includes: reporting maximum allowed power reduction (P-MPR) information to a base station, wherein the P-MPR information is used to indicate a maximum power reduction supported by the UE in a current communication frequency band; receiving scheduling information returned by the base station based on the P-MPR information; and transmitting uplink data according to the scheduling information.

Methods and apparatuses for configuring PUSCH pathloss reference signal for SRI PUSCH power control are disclosed. A method comprises configuring PUSCH pathloss reference signal for one or more SRI PUSCH power controls by using a MAC CE, and transmitting a PDSCH carrying the MAC CE.

A terminal apparatus transmits a PUCCH in a certain slot, and receives multiple DCI formats on a set of PDCCH monitoring occasions corresponding to the certain slot. In a case that multiple PUCCHs exist in the certain slot and that the multiple PUCCHs include a first PUCCH including a first type HARQ-ACK codebook and a second PUCCH including a second type HARQ-ACK codebook, the second PUCCH is not transmitted.

A terminal including: a reception unit configured to receive feedback information for uplink transmission based on a configured grant from a base station apparatus; a control unit configured to determine an application target of a transmission power control command included in the feedback information; and a transmission unit configured to apply the transmission power control command to uplink transmission of the application target.

Aspects presented herein may enable FD devices to apply power backoff and/or power allocation prioritization rules that are specific to FD transmissions. In one aspect, a UE determines an FD specific power backoff associated with each of at least one transmission of a plurality of transmissions in a slot that is configured as an FD slot, each FD specific power backoff is based on whether a corresponding transmission would cause self-interference with a DL reception in the FD slot, and the plurality of transmissions are overlapping in time. The UE determines a transmission power for each of the at least one transmission in the FD slot based on the determined FD specific power backoff for each of the at least one transmission. The UE transmits one or more of the at least one transmission based on the determined transmission power for the corresponding transmission.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with artificial noise assisted physical layer security for at least one of an uplink channel or a sidelink channel. The UE may receive an indication of a power allocation parameter associated with a power allocation between a data signal and an artificial noise signal. The UE may transmit, via the uplink channel or the sidelink channel, at least one of the data signal or the artificial noise signal with the power allocation between the data signal and the artificial noise signal based at least in part on the power allocation parameter. Numerous other aspects are described.

Methods, apparatuses, and computer-readable medium are provided for enabling DCI based power control for PUCCH. An example method includes receiving, from a network entity, a DCI comprising a group TPC message, the DCI indicating multiple TPCs including one or more TPCs associated with one or more secondary cells and a primary cell for the UE and one or more other UEs. The example method further includes identifying a TPC to be applied to a target secondary cell or a target primary cell from the one or more TPCs. The example method further includes transmitting, to the base station, a PUCCH on the target secondary cell or the target primary cell based on the identified TPC from the one or more TPCs.

This disclosure provides methods, devices, and systems supporting power control parameter configuration for configured grants (CGs). In some implementations, a user equipment (UE) may receive control signaling configuring multiple sounding reference signal (SRS) resource sets and multiple sets of power control parameters for CG uplink transmission. The UE may receive downlink control information (DCI) scheduling a retransmission and indicating which set of power control parameters the UE is to use for the CG uplink retransmission. In some other implementations, the control signaling may configure multiple SRS resources sets but a single set of power control parameters. The UE may receive DCI activating the CG configuration or scheduling a retransmission, the DCI indicating a second set of power control parameters not configured by the control signaling. The UE may automatically use the power control parameters configured by the control signaling or may determine a second set based on the DCI.

This disclosure provides methods for transmissions and retransmissions over a configured grant (CG) physical uplink shared channel (PUSCH) and for transmissions over physical uplink control channel (PUCCH) resources in multi-transmission and reception point (TRP) deployments. A user equipment (UE) may receive signaling configuring a first set of power control parameters and a second set of power control parameters for a CG-PUSCH resource. Additionally or alternatively, the UE may receive signaling activating a first closed-loop power control operation and a second closed-loop power control operation for a PUCCH resource. In some scenarios, the UE may receive a fallback downlink control information (DCI) format activating or scheduling the CG-PUSCH resource or indicating the PUCCH resource. In such scenarios, the UE may employ one or both of a power control selection rule or a transmit power control (TPC) command application rule for a transmission over the CG-PUSCH resource or the PUCCH resource.
