Abstract

A method of transmitting data is performed by detecting a triggering of a first event, further detecting a triggering of a second event until a third event occurs, and performing a first action if the triggering of the second event is not detected, wherein the first action is based on the detected first event. The first event may be the expiry of a poll retransmit timer, the second event may be a detecting whether a ACK or NACK is not received, the third event may be a next transmission opportunity, and the first action may be setting a polling bit of a data PDU to be transmitted.

Claims

1. A method of transmitting data, the method comprising:

detecting a triggering of a first event;

further detecting a triggering of a second event until a third event occurs; and

performing a first action if the triggering of the second event is not detected, wherein the first action is based on the detected first event.

2. The method of claim 1, wherein if the triggering of the second even is detected, canceling the first event.

3. The method of claim 1, wherein the first event is an expiry of a poll retransmit timer, the second event is detecting whether a ACK or NACK signal is not received, and the third event is a next transmission opportunity,

4. The method of claim 3, wherein the first action may be setting a polling bit of a data PDU (protocol data unit) to be transmitted.

5. A method of transmitting data, the method comprising:

detecting an expiry of a poll retransmit timer;

further detecting whether a positive or negative acknowledgement for a (RLC) data PDU was not received, the further detecting step being performed until the next transmission opportunity;

if the positive or negative acknowledgement was not detected or received, setting a polling bit in the data PDU; and

transmitting the data PDU having the polling bit set therein.

6. The method of claim 5, wherein the next transmission opportunity occurs when an instruction is received from the MAC layer indicating that transmission is possible because radio resources are available.

7. The method of claim 6, wherein the radio resources are used for supporting OFDM.

8. The method of claim 5, wherein the further detecting step is performed during a further confirmation period defined as a fixed or variable time duration.

9. The method of claim 5, wherein the further detecting step is timer-based.
