Abstract

A method for controlling data retransmission at a transmitting side in a wireless communication system is provided. In the method, the transmitting side transmits a new transmission packet to a receiving side. The transmitting side then transmits reason indication information, indicating a reason why the transmitting side has initiated the transmission of the new transmission packet, to the receiving side.

Claims

1. A method for controlling data retransmission at a transmitting side in a wireless communication system, the method comprising:

transmitting a new transmission packet to a receiving side, the new transmission packet not being a retransmission packet to be transmitted to the receiving side in response to a negative acknowledgement signal (NACK) transmitted from the receiving side; and

transmitting reason indication information, indicating a reason why the transmitting side has initiated the transmission of the new transmission packet, to the receiving side,

wherein the reason indication information is included in the new transmission packet to be transmitted to the receiving side,

wherein the reason why the transmitting side has initiated the transmission of the new transmission packet is because the number of times a specific packet has been previously transmitted to the receiving side has reached a preset maximum transmission count.

2. The method according to claim 1, wherein the reason why the transmitting side has initiated the transmission of the new transmission packet is because the transmitting side has received an acknowledgement signal (ACK) from the receiving side in response to a packet previously transmitted to the receiving side.

3. The method according to claim 1, wherein the reason why the transmitting side has initiated the transmission of the new transmission packet is because the new transmission packet is associated with a service with higher priority than a service associated with a packet previously transmitted to the receiving side.

4. A method for controlling data retransmission at a receiving side in a wireless communication system, the method comprising:

receiving a new transmission from a transmitting side, the new transmission packet not being a retransmission packet to be transmitted by the transmitting side in response to a negative acknowledgement signal (NACK) transmitted to the transmitting side; and

receiving reason indication information, indicating a reason why the transmitting side has initiated the transmission of the new transmission packet, from the transmitting side,

wherein the reason indication information is received by being incorporated in the new transmission packet,

wherein the reason indication information indicates that the reason why the transmitting side has initiated the transmission of the new transmission packet is because the number of times a specific packet has been previously transmitted to the receiving side has reached a preset maximum transmission count.

5. The method according to claim 4, wherein the reason indication information indicates that the reason why the transmitting side has initiated the transmission of the new transmission packet is because the transmitting side has received an acknowledgement signal (ACK) from the receiving side in response to a packet most recently transmitted to the receiving side.

6. The method according to claim 5, further comprising transmitting an error report message to the transmitting side when the receiving side has not transmitted an acknowledgement signal (ACK) to the transmitting side in response to the packet most recently received by the receiving side.

7. The method according to claim 6, wherein the error report message includes time information associated with the packet most recently received by the receiving side.

8. The method according to claim 7, wherein the time information is information of the time at which the receiving side has transmitted a negative acknowledgement signal (NACK) in response to the packet most recently received by the receiving side.

9. The method according to claim 4, wherein the reason indication information indicates that the reason why the transmitting side has initiated the transmission of the new transmission packet is because the new transmission packet is associated with a service with higher priority than a service associated with a packet previously transmitted from the transmitting side to the receiving side.
