Abstract

Aspects for sending structured measurement data based on a specific type of measurement requested by a network are disclosed. A user equipment (UE) may receive a request from a base station for minimization of driving test (MDT) data corresponding to a specified type of measurement by the UE from a larger plurality of available MDT measurements that the UE can make. The UE can send the requested data including a structure report having results for the specified measurement type to the base station. In other aspects, a base station may send a request to a UE for minimization of driving test (MDT) data corresponding to a type of measurement by the UE. The base station may receive the requested data corresponding to the type of measurement.

Claims (55)

1 . A method of wireless communication of a user equipment (UE), comprising:

receiving, from a base station, a request for structured minimization of driving test (MDT) data, the requested data corresponding to at least one type of MDT measurement specified by the base station from a larger plurality of available MDT measurement types that can be performed by the UE, the request for the structured MDT data including an indication that the base station supports non-real time streaming MDT data based on a uniform resource identifier (URI), a hypertext transfer protocol (HTTP), or HTTP Secure (HTTPS); and

sending the data specific to the at least one type of MDT measurement type specified by the base station as a single file in a structured report, the data including results corresponding to the specified at least one type of MDT measurement to the base station.

2 . The method of claim 1 , wherein the at least one type of MDT measurement is specified by the base station at a time of sending the request.

3 . The method of claim 1 , further comprising performing a measurement corresponding to the specified at least one type of MDT measurement.

4 . The method of claim 1 , further comprising sending the data to the base station over a control plane.

5 . The method of claim 1 , wherein the requested MDT data includes results specific to at least one type of MDT measurement specified by the base station.

6 . The method of claim 1 , further comprising sending, to the base station, information comprising a capability bit to indicate selective MDT report support.

7 . The method of claim 1 , further comprising:

receiving, after sending the data, another request from the base station for structured MDT data including results corresponding to another type of MDT measurement specified by the base station; and

sending the requested data to the base station corresponding to the another type of MDT measurement.

8 . The method of claim 1 , further comprising:

performing a measurement corresponding to the at least one type of MDT measurement specified by the base station;

saving results of the measurement in a separate file; and

sending the separate file including the results to the base station.

9 . The method of claim 1 , further comprising:

sending a message to the base station indicating that the UE is not ready to transmit the requested MDT data,

wherein the results are later sent to the base station when the UE is ready.

10 . The method of claim 9 , wherein the message includes a UE assistance information message sent in response to the request for the structured MDT data for notifying the base station that the UE is not currently ready or capable to transmit the requested MDT data.

11 . The method of claim 1 , wherein the results are sent using non-real time data streaming.

12 . A user equipment (UE), comprising:

a memory; and

at least one processor coupled to the memory and configured to:

receive, from a base station, a request for structured minimization of driving test (MDT) data, the requested data corresponding to at least one type of MDT measurement specified by the base station from a larger plurality of available MDT measurement types that can be performed by the UE, the request for the structured MDT data including an indication that the base station supports non-real time streaming MDT data based on a uniform resource identifier (URI), a hypertext transfer protocol (HTTP), or HTTP Secure (HTTPS); and

send the data specific to the at least one type of MDT measurement type specified by the base station as a single file in a structured report, the data including results corresponding to the specified at least one type of MDT measurement to the base station.

13 . The UE of claim 12 , wherein the at least one type of MDT measurement is specified by the base station at a time of sending the request.

14 . The UE of claim 12 , wherein the at least one processor is further configured to perform a measurement corresponding to the specified at least one type of MDT measurement.

15 . The UE of claim 12 , wherein the at least one processor is further configured to send the data to the base station over a control plane.

16 . The UE of claim 12 , wherein the requested MDT data includes results specific to at least one type of MDT measurement specified by the base station.

17 . The UE of claim 12 , wherein the at least one processor is further configured to:

perform a measurement corresponding to the at least one type of MDT measurement specified by the base station;

save results of the measurement in a separate file; and

send the separate file including the results to the base station.

18 . The UE of claim 12 , wherein the at least one processor is further configured to send a message to the base station indicating that the UE is not ready to transmit the requested MDT data,

wherein the results are later sent to the base station when the UE is ready.

19 . The UE of claim 18 , wherein the message includes a UE assistance information message sent in response to the request for the structured MDT data and configured to notify the base station that the UE is not currently ready or capable to transmit the requested MDT data.

20 . The UE of claim 12 , wherein the results are sent using non-real time data streaming.

21 . A method of wireless communication of a base station, comprising:

sending a request to a UE for structured minimization of driving test (MDT) data, the requested MDT data corresponding to at least one type of MDT measurement specified by the base station from a larger plurality of available MDT measurement types that can be performed by the UE, the request for the structured MDT data including an indication that the base station supports non-real time streaming MDT data based on a uniform resource identifier (URI), a hypertext transfer protocol (HTTP), or HTTP Secure (HTTPS); and

receiving the data specific to the at least one type of MDT measurement type specified by the base station as a single file in a structured report, the data including results corresponding to the specified at least one type of MDT measurement from the UE.

22 . The method of claim 21 , further comprising forwarding the requested MDT data via a trace collection entity (TCE) to a core network for distributing to clients.

23 . The method of claim 21 , wherein the requested MDT data comprises a plurality of measurement types.
