Abstract

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus includes an user equipment which is configured to measure Minimization of Drive Tests (MDT) metrics, to measure Quality of Experience (QoE) metrics, to generate correlation information of at least one of the MDT metrics and at least one of the QoE metrics, and to report the correlation information.

First claim

1. A method of wireless communication by an apparatus, comprising:
measuring Minimization of Drive Tests (MDT) metrics;
measuring Quality of Experience (QoE) metrics;
generating correlation information of at least one of the MDT metrics and at least one of the QoE metrics;
combining the MDT metrics and the QoE metrics; and
reporting the correlation information and the combined MDT metrics and the QoE metrics using Radio Resource Control (RRC) signaling, wherein the RRC signaling comprises an RRC message, the QoE metrics being in a container or at least one parameter of the RRC message.

2. The method of claim 1 , wherein the correlation information includes time information of a user equipment (UE) engaged in a multimedia session.

3. The method of claim 1 , wherein the correlation information includes an identification of a UE engaged in a multimedia session.

4. The method of claim 1 , wherein the correlation information includes an identification of a multimedia session.

5. The method of claim 1 , wherein the correlation information includes information to correlate a Real-time Transport Protocol (RTP) data unit of a multimedia session with a Packet Data Convergence Protocol (PDCP) data unit.

6. The method of claim 1 , further comprising:
configuring a user equipment (UE) for the measuring the QoE metrics via the RRC signaling.

7. The method of claim 1 , further comprising configuring a user equipment (UE) for the measuring of the QoE metrics via the RRC message.

8. The method of claim 1 , wherein the measuring the MDT metrics and the measuring the QoE metrics are performed based on a measurement interval.

9. The method of claim 1 , wherein the MDT metrics and the QoE metrics are reported based on a reporting interval.

10. An apparatus for wireless communication, comprising:
means for measuring Minimization of Drive Tests (MDT) metrics;
means for measuring Quality of Experience (QoE) metrics;
means for generating correlation information of at least one of the MDT metrics and at least one of the QoE metrics;
means for combining the MDT metrics and the QoE metrics; and
means for reporting the correlation information and the combined MDT metrics and the QoE metrics using Radio Resource Control (RRC) signaling, wherein the RRC signaling comprises an RRC message, the QoE metrics being in a container or at least one parameter of the RRC message.

11. The apparatus of claim 10 , wherein the correlation information includes time information of a user equipment (UE) engaged in a multimedia session.
