For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.

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.

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.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) scheduling transmission of a first one or more physical uplink control channel (PUCCH) communications on a first component carrier and a second one or more PUCCH communications on a second component carrier, wherein the DCI includes information identifying a first transmit power configuration for the first one or more PUCCH communications and a second transmit power configuration for the second one or more PUCCH communications. The UE may transmit the first one or more PUCCH communications in accordance with the first transmit power configuration and the second one or more PUCCH communications in accordance with the second transmit power configuration. Numerous other aspects are described.

A method for a terminal to transmit a Sounding Reference Signal (SRS) in a wireless communication system according to an embodiment includes the steps of: receiving setting information about an SRS; transmitting a message including information about Power Headroom (PH) related to the transmission power of the SRS; receiving Downlink Control Information (DCI) for triggering the transmission of the SRS; and transmitting the SRS. The PH is characterized by being related to a Power Headroom Report (PHR) of a specific type, wherein the specific type is based on the type of the PHR for a serving cell in which a Physical Uplink Shared Channel (PUSCH) and a Physical Uplink Control Channel (PUCCH) are not set.
