Abstract
Provided is a method of operating a transmitting user equipment (UE) in a wireless communication system. The method includes receiving a first radio resource control (RRC) configuration-related message by the transmitting UE (Tx UE), and transmitting a message to a receiving UE by the Tx UE. The first RRC configuration-related message includes sidelink hybrid automatic repeat request (HARQ) enable or HARQ disable configuration information.
Claims10
A method of operating a transmitting user equipment (Tx UE) in a wireless communication system, the method comprising:
- receiving, by the Tx UE, a first radio resource control (RRC) configuration-related message;
- and
- transmitting, by the Tx UE, a message to a receiving UE (Rx UE),
- wherein the first RRC configuration-related message includes information that informs whether sidelink hybrid automatic repeat request (HARQ) is enabled or disabled, and
- wherein whether the sidelink HARQ is enabled or disabled is configured per logical channel group,
- wherein based on receiving the first RRC configuration-related message, the Tx UE transmits a second configuration-related message to the Rx UE, and
- wherein the second configuration-related message includes sidelink HARQ enable or HARQ disable configuration information.
A method of operating a receiving user equipment (Rx UE) in a wireless communication system, the method comprising:
- receiving, by the Rx UE, a message from a transmitting UE (Tx UE) which has received a first radio resource control (RRC) configuration-related message,
- wherein the first RRC configuration-related message includes information that informs whether sidelink hybrid automatic repeat request (HARQ) is enabled or disabled, and
- wherein whether the sidelink HARQ is enabled or disabled is configured per logical channel group,
- wherein the Rx UE receives a second configuration-related message from the Tx UE which has received the first RRC configuration-related message, and
- wherein the second configuration-related message includes sidelink HARQ enable or HARQ disable configuration information.
A transmitting user equipment (Tx UE) configured to operate in a wireless communication system, the Tx UE comprising:
- at least one processor;
- and
- at least one computer memory operatively coupled to the at least one processor and storing instructions which, when executed, cause the at least one processor to perform operations comprising:
- receiving, by the Tx UE, a first radio resource control (RRC) configuration-related message;
- and
- transmitting, by the Tx UE, a message to a receiving UE,
- wherein the first RRC configuration-related message includes information that informs whether sidelink hybrid automatic repeat request (HARQ) is enabled or disabled, and
- wherein whether the sidelink HARQ is enabled or disabled is configured per logical channel group,
- wherein upon receipt of the first RRC configuration-related message, the Tx UE transmits a second configuration-related message to the Rx UE, and
- wherein the second configuration-related message includes sidelink HARQ enable or HARQ disable configuration information.
