The present invention includes a receiver configured to receive first information, the first information including information for configuring whether transform precoding for a physical uplink shared channel is enabled, and a transmitter configured to transmit information indicating a first power headroom level for the physical uplink shared channel with the transform precoding enabled and information indicating a second power headroom level for the physical uplink shared channel with the transform precoding not enabled.

The present invention includes a receiver configured to receive first information, the first information including information for configuring whether transform precoding for a physical uplink shared channel is enabled, and a transmitter configured to transmit information indicating a first power headroom level for the physical uplink shared channel with the transform precoding enabled and information indicating a second power headroom level for the physical uplink shared channel with the transform precoding not enabled.

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.

Embodiments of this disclosure relate to the communications field, and provide a repeated transmission method and an apparatus, to increase a probability of successful decoding of a user equipment. The method includes: performing, by a user equipment, first transmission of uplink data, and sending a first reference signal to a network device based on a first transmit power, where the first reference signal is used to demodulate the first transmission of the uplink data; and performing, by the user equipment, N.sup.th transmission of the uplink data, and sending a second reference signal to the network device based on a second transmit power, where N is an integer greater than or equal to 2, the second reference signal is used to demodulate the N.sup.th transmission of the uplink data, and the second transmit power is less than the first transmit power.

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

An unlicensed carrier power control method is provided. Multiple transmitted power constraint parameters are acquired, and a minimum value in the multiple transmitted power constraint parameters is determined. Power control is performed according to the minimum value in the multiple transmitted power constraint parameters. An unlicensed carrier power control device and a storage medium are also provided.

Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. A time adjustment may be determined and applied to uplink transmission timing of a cell group. A transmission timing difference between a first cell group and a second cell group may be determined. If the transmission timing difference exceeding a threshold, one or more devices may stop transmitting uplink signals via one or more secondary cells and/or may stop applying the timing adjustment for a cell group.
