Terminal device, base station device, method for controlling terminal device, and method for controlling base station device

A base station device comprising

• a communication unit and a control unit,
• wherein the control unit is configured to
• transmit disabling information of hybrid automatic repeat request (HARQ) feedback via the communication unit, and
• recognize that one or more HARQ processes indicated by the disabling information of the HARQ feedback are disabled, and
• the disabling information of the HARQ feedback is set for each HARQ process,
• wherein the control unit transmits the disabling information of the HARQ feedback in semi-static notification,
• wherein the semi-static notification is RRC Setup,
• wherein the disabling information of the HARQ feedback includes identification information of a disabled HARQ process among the one or more HARQ processes,
• wherein the disabling information of the HARQ feedback indicates starting HARQ-RTT-TimerDL when one or more pieces of HARQ feedback indicated by the disabling information of the HARQ feedback are enabled,
• wherein the control unit is further configured to:
• start the HARQ-RTT-TimerDL for a corresponding HARQ process in a first symbol after a last symbol of a corresponding transmission carrying the HARQ feedback when one or more pieces of HARQ feedback indicated by the disabling information of the HARQ feedback are enabled,
• wherein the HARQ-RTT-TimerDL is for Non-Terrestrial Network (NTN) communication,
• wherein a value of the HARQ-RTT-TimerDL for NTN communication is larger than a value of a HARQ-RTT-TimerDL for a Terrestrial Network (TN) communication.

A method for controlling a terminal device, the method comprising:

• receiving disabling information of hybrid automatic repeat request (HARQ) feedback via a communication unit;
• recognizing that one or more HARQ processes indicated by the disabling information of the HARQ feedback are disabled;
• and
• setting the disabling information of the HARQ feedback for each HARQ process,
• wherein the disabling information of the HARQ feedback is transmitted in semi-static notification from a base station device,
• wherein the semi-static notification is RRC Setup,
• wherein the disabling information of the HARQ feedback includes identification information of a disabled HARQ process among one or more HARQ processes,
• wherein the disabling information of the HARQ feedback indicates starting HARQ-RTT-TimerDL when one or more pieces of HARQ feedback indicated by the disabling information of the HARQ feedback are enabled,
• wherein the control unit is further configured to:
• start the HARQ-RTT-TimerDL for a corresponding HARQ process in a first symbol after a last symbol of a corresponding transmission carrying the HARQ feedback when one or more pieces of HARQ feedback indicated by the disabling information of the HARQ feedback are enabled,
• wherein the HARQ-RTT-TimerDL is for Non-Terrestrial Network (NTN) communication,
• wherein a value of the HARQ-RTT-TimerDL for NTN communication is larger than a value of a HARQ-RTT-TimerDL for a Terrestrial Network (TN) communication.
