3. The method of claim 1 , further comprising the user equipment:

before the detecting the first communication failure with the base station, transmitting a first measurement report.

4. The method of claim 3 , wherein the first measurement report includes one or more of:

a first measurement result measured on a measurement object; or

a first measurement identity that identifies the first measurement configuration.

5. The method of claim 1 , further comprising the user equipment:

in response to detecting the first communication failure with the base station, transmitting an RRC Reestablishment Request message to the base station;

in response to the transmitting the RRC Reestablishment Request message, receiving an RRC Reestablishment message from the base station; and

in response to the receiving the RRC Reestablishment message, resuming the performing the first measurement process.

6. The method of claim 5 , further comprising the user equipment:

in response to the receiving the RRC Reestablishment message, transmitting an RRC Reestablishment complete message before the resuming the first measurement process.

7. The method of claim 5 , further comprising the user equipment:

in response to the receiving the RRC Reestablishment message, transmitting an RRC Reestablishment complete message after the resuming the first measurement process.

8. The method of claim 5 , further comprising the user equipment:

transmitting a second measurement report.

9. The method of claim 1 , further comprising the user equipment:

receiving a second measurement configuration from the base station;

determining if the second measurement configuration includes an indication to release the first measurement configuration; and

based on determining that the second measurement configuration includes the indication to release the first measurement configuration, releasing the first measurement configuration; or

based on determining that the second measurement configuration does not include the indication to release the first measurement configuration:

maintaining the first measurement configuration; and

resuming the performing the first measurement process.

10. The method of claim 1 , wherein the first measurement configuration includes one or more of:

a first measurement object to be measured;

a first measurement identity identifying the first measurement configuration;

a measurement reporting configuration; or

an absolute radio frequency channel number (ARFCN) and a reference signal to be measured.

11. The method of claim 1 , further comprising the user equipment:

suspending the performing the first measurement process.

12. A user equipment comprising:

a wireless transceiver; and

a processor and memory system to implement a measurement manager application configured to:

receive a first measurement configuration from a base station;

based on the first measurement configuration, perform a first measurement process;

detect a first communication failure with the base station;

in response to detecting the first communication failure with the base station:

release a measurement gap configuration; and

maintain the first measurement configuration.

13. The user equipment of claim 12 , wherein the measurement manager application is configured to:

in response to the detection of the first communication failure with the base station, transmit an RRC Reestablishment Request message to the base station; and

in response to the transmission of the RRC Reestablishment Request message, receive an RRC Reestablishment message from the base station.

14. The user equipment of claim 12 , wherein the measurement manager application is configured to:

before the detection of the first communication failure with the base station, transmit a first measurement report;

in response to the detection of the first communication failure with the base station, transmit an RRC Reestablishment Request message to the base station;

in response to the transmission of the RRC Reestablishment Request message, receive an RRC Reestablishment message from the base station; and

in response to the reception of the RRC Reestablishment message, resume the performance of the first measurement process.

15. The user equipment of claim 14 , wherein first measurement report includes one or more of:

a first measurement result measured on a first measurement object; or

a first measurement identity that identifies the first measurement configuration.

16. The user equipment of claim 12 , wherein the measurement manager application is configured to:

in response to the detection of the first communication failure with the base station:

continue the performance of the first measurement process.

17. The user equipment of claim 12 , wherein the first measurement configuration includes one or more of:

a first measurement object to be measured;

a first measurement identity identifying the first measurement configuration;

a measurement reporting configuration; or

an absolute radio frequency channel number (ARFCN) and a reference signal to be measured.

18. The user equipment of claim 12 , wherein the measurement manager application is configured to:

suspend the performance of the first measurement process.

19. A method of reestablishing a radio resource control (RRC) connection, the method comprising a user equipment:

receiving a first measurement configuration from a base station;

receiving a second measurement configuration from the base station;

based on the first measurement configuration, performing a first measurement process;

transmitting a first measurement report;

detecting a first communication failure with the base station;

in response to detecting the first communication failure with the base station:

releasing the second measurement configuration;

suspending communication with the base station over a first signaling radio bearer (SRB); and

maintaining the first measurement configuration.

20. The method of claim 19 , further comprising the user equipment:

in response to detecting the first communication failure with the base station, transmitting an RRC Reestablishment Request message to the base station;

in response to the transmitting the RRC Reestablishment Request message, receiving data over the first SRB from the base station;

receiving an RRC Reestablishment message from the base station;

in response to the receiving the RRC Reestablishment message, determining to resume the transmission of additional measurement reports; and

transmitting a second measurement report.

21. The method of claim 19 , wherein the first measurement configuration includes one or more of:

a first measurement object to be measured;

a first measurement identity identifying the first measurement configuration;

a measurement reporting configuration; or

an absolute radio frequency channel number (ARFCN) and a reference signal to be measured.

22. The method of claim 19 , wherein the first measurement report includes one or more of:

a first measurement result measured on a measurement object; or

a first measurement identity that identifies the first measurement configuration.
