NTN-entity, user equipment and base station involved in transmission procedure

A user equipment (UE), comprising:

• a transmitter, which, in operation, transmits a channel status report to a non-terrestrial network (NTN) entity, the channel status report providing information on a channel between the UE and the NTN entity;
• a processor, which, in operation, determines an updated channel status of the channel between the UE and the NTN entity;
• and
• a receiver, which, in operation, receives, from the NTN entity, uplink scheduling information for an uplink transmission of uplink data from the UE to the NTN entity;
• wherein the processor, when in operation, determines whether to adapt a transmission power of the uplink transmission of the uplink data, based on the updated channel status,
• wherein the processor, when having determined to adapt the transmission power, adapts the transmission power,
• wherein the transmitter, when in operation, performs the uplink transmission of the uplink data to the NTN entity according to the received uplink scheduling information and based on the adapted transmission power,
• wherein the determination of whether to adapt the transmission power of the scheduled uplink transmission of the uplink data takes into account a priority of the uplink data, and
• wherein the determining whether to adapt the transmission power for the scheduled uplink transmission is further based on a minimum transmission-related parameter to be fulfilled for the scheduled uplink transmission.

A base station comprising:

• a receiver, which, in operation, receives a channel status report from a non-terrestrial network (NTN) entity providing information on a channel between a user equipment (UE) and the NTN entity;
• a processor, which, in operation, prepares a plurality of different uplink scheduling information for transmission of uplink data by the UE based on the received channel status report, the different uplink scheduling information at least differing among each other in a value of transmission power;
• a transmitter, which, in operation, transmits the prepared plurality of different uplink scheduling information to the NTN entity,
• wherein the transmission power of the scheduled uplink transmission of the uplink data is adapted based on a priority of the uplink data, and
• wherein the transmission power of the scheduled uplink transmission of the uplink data is adapted further based on a minimum transmission-related parameter to be fulfilled for the scheduled uplink transmission.
