Abstract

The disclosure is directed to a method and apparatuses for controlling quality of experience (QoE) based on UE assisted feedback. In one aspect, the method would include not limited to: receiving an enable indicator which indicates a first feedback signaling to be transmitted; performing a quality of experience (QoE) evaluation for fulfilling a performance requirement; and transmitting the first feedback signaling including a first preferred configuration of licensed wireless connection in response to performing the QoE evaluation, wherein the wireless connection comprises a licensed wireless connection and a licensed-assisted access connection.

Claims

1. A method used by a user equipment for controlling quality of user experience (QoE) based on user equipment (UE) assisted feedback, the method comprising:

receiving an enable indicator which indicates a first feedback signaling to be transmitted;

performing a quality of experience (QoE) evaluation for fulfilling a performance requirement; and

transmitting the first feedback signaling comprising a first preferred configuration of a wireless connection in response to performing the QoE evaluation, wherein the wireless connection comprises a licensed wireless connection and a licensed-assisted access connection.

2. The method of claim 1 further comprising:

receiving a first configuration message comprising a timer configuration for a first timer, a second timer, and a third timer, wherein the timer configuration comprising a duration for each of the first timer, second timer, and third timer.

3. The method of claim 2 further comprising:

starting the first timer in response to transmitting the first feedback signal; and

re-transmitting, after transmitting the first feedback signaling, the first feedback signaling after the first timer has expired without receiving any configuration message associated with the first feedback signal.

4. The method of claim 2 further comprising:

starting the second timer in response to transmitting the first feedback signal;

performing, after transmitting the first feedback, another iteration of the QoE evaluation for fulfilling the performance requirement; and

transmitting, after transmitting the first feedback signaling, a second feedback signaling comprising a second preferred configuration in response to the QoE evaluation after the second timer has expired.

5. The method of claim 1 further comprising:

receiving a second configuration message which comprises a deny indicator which rejects the first preferred configuration.

6. The method of claim 5 further comprising:

starting the third timer in response to receiving the second configuration message;

performing, after receiving the first configuration, another iteration of the QoE evaluation for fulfilling the performance requirement; and

transmitting, after receiving the second configuration message, a third feedback signaling comprising the second preferred configuration in respond to the another iteration of the QoE evaluation after the third timer has expired.

7. The method of claim 5, wherein the second configuration message further comprises one or a combination of inquiring an updated preferred configuration, an updated status report, and an updated measurement report.

8. The method of claim 1 further comprising:

receiving, after transmitting the first feedback signaling, a third configuration message comprising one or a combination of a configured radio configuration and a configured direction command.

9. The method of claim 1, wherein the first preferred configuration comprising one of updating the radio configuration, the direction command, the status report, the measurement report, and an updating cause.

10. The method of claim 1, wherein performing the QoE evaluation for fulfilling the performance requirement further comprising:

detecting any one of loading, buffer latency, buffered data, packet loss, error rate, dropping rate, data rate, channel, bandwidth, spectrum frequency, MCS, and hardware issues.

11. The method of claim 9, wherein the radio configuration comprising one or a combination of channel, frequency, MCS, bandwidth, data rate, coding rate, buffer size, power level, antenna configuration, and aggregation capability.
