Abstract

Examples described herein relate to systems and methods for a wireless communication device to manage cell measurements, including, but not limited to, performing measurements based on a first measurement configuration message received from a network, receiving a second measurement configuration message from the network before the measurements based on the first measurement configuration message are completed, and continuing to perform measurements based on the first measurement configuration message after receiving the second measurement configuration message.

Claims (48)

1. A method for a wireless communication device to manage cell measurements, the method comprising:

receiving a first measurement configuration message received from a network, wherein the first measurement configuration message is a first System Information Block (SIB);

receiving a second measurement configuration message from the network before the measurements based on the first measurement configuration message are completed, wherein the second measurement configuration message is a second SIB;

lowering a priority of the second SIB to less than a priority of the first SIB;

performing measurements based on the first measurement configuration message after receiving the second measurement configuration message;

aborting performing the measurements based on the first measurement configuration message in response to determining that the priority of the second SIB is no longer less than the priority of the first SIB; and

performing measurements based on the second measurement configuration message in response to determining that the performing measurements based on the first measurement configuration message have been aborted.

2. The method of claim 1 , wherein

performing the measurements based on the first measurement configuration message in response to receiving the first measurement configuration message from the network.

3. The method of claim 1 , wherein the measurements based on the first measurement configuration message are performed while the wireless communication device is in a connected mode with respect to the network.

4. The method of claim 3 , wherein:

the first measurement configuration message identifies a first target neighbor cell; and

the second measurement configuration message identifies a second target neighbor cell.

5. The method of claim 4 , wherein each of the first target neighbor cell and the second target neighbor cell is an inter-frequency neighbor cell or an inter-Radio Access Technology (RAT) neighbor cell to a serving cell.

6. The method of claim 4 , wherein performing the measurements based on the first measurement configuration message comprises performing an initial acquisition to camp on the first target neighbor cell.

7. The method of claim 3 , further comprising adding the second target neighbor cell to a list of target neighbor cells to be measured.

8. The method of claim 7 , wherein the measurements based on the first measurement configuration message are continued to be performed in response to one of:

adding the second target neighbor cell to the list of target neighbor cells to be measured; or

receiving the second measurement configuration message from the network.

9. The method of claim 3 , wherein:

the first measurement configuration message identifies a first reporting criteria; and

the second measurement configuration message identifies a second reporting criteria.

10. The method of claim 9 , wherein each of the first reporting criteria and the second reporting criteria is a reporting configuration, reporting threshold, reporting interval, or reporting Time-To-Trigger (TTT).

11. The method of claim 9 , wherein performing the measurements based on the first measurement configuration message comprises of performing an initial acquisition to camp on a target neighbor cell using the first reporting criteria.

12. The method of claim 9 , further comprising storing the second reporting criteria.

13. The method of claim 12 , wherein the measurements based on the first measurement configuration message are continued to be performed in response to one of:

storing the second reporting criteria; or

receiving the second measurement configuration message from the network.

14. The method of claim 3 , wherein the first measurement configuration message and the second measurement configuration message are each a Radio Resource Control (RRC) reconfiguration Over-The-Air (OTA) message.

15. The method of claim 1 , wherein the measurements based on the first measurement configuration message are performed while the wireless communication device is in an idle mode with respect to the network.

16. A wireless communication device, comprising:

a Radio Frequency (RF) resource;

a processor; and

a memory storing instructions that, when executed by the processor, cause the wireless communication device to:

receive a first measurement configuration message from a network, wherein the first measurement configuration message is a first System Information Block (SIB);

receive a second measurement configuration message from the network before the measurements based on the first measurement configuration message are completed, wherein the second measurement configuration message is a second SIB;

lowering a priority of the second SIB to less than a priority of the first SIB;

perform measurements based on the first measurement configuration message after receiving the second measurement configuration message;

abort performing the measurements based on the first measurement configuration message in response to determining that the priority of the second SIB is no longer less than the priority of the first SIB; and

perform measurements based on the second measurement configuration message in response to a determination that performing the measurements based on the first measurement configuration message have been aborted.

17. The wireless communication device of claim 16 , wherein the first measurement configuration message conflicts with the second measurement configuration message.

18. A wireless communication device, comprising:

means for receiving a first measurement configuration message received from a network, wherein the first measurement configuration message is a first System Information Block (SIB);

means for receiving a second measurement configuration message from the network before the measurements based on the first measurement configuration message are completed, wherein the second measurement configuration message is a second SIB;

means for lowering a priority of the second SIB to less than a priority of the first SIB;

means for performing measurements based on the first measurement configuration message after receiving the second measurement configuration message;

means for aborting performing the measurements based on the first measurement configuration message in response to determining that the priority of the second SIB is no longer less than the priority of the first SIB; and

means for performing measurements based on the second measurement configuration message in response to determining that the measurements based on the first measurement configuration message have been aborted.
