License assisted access measurement

1. An arrangement configured to be employed within a user equipment (UE), the arrangement comprising:

control circuitry to:

obtain a measurement configuration, where the measurement configuration complies with license assisted access (LAA) and includes a measurement window;

obtain one or more discovery reference signals (DRS) during the measurement window;

generate a target cell measurement based on the one or more DRS and the measurement configuration;

dynamically determine whether to use a single shot or a multi-shot based on the target cell measurement to request communication use of an unlicensed band; and

generate a measurement report that includes the target cell measurement.

2. The arrangement of claim 1 , wherein the measurement configuration includes a measurement type pre-configured by an eNodeB.

3. The arrangement of claim 1 , wherein the measurement configuration includes a measurement type pre-configured by the UE.

4. The arrangement of claim 1 , wherein the measurement window includes a plurality of DRS.

5. The arrangement of claim 1 , wherein at least one of the one or more DRS is not available as a result of a listen before talk (LBT) operation performed by an eNodeB.

6. The arrangement of claim 1 , wherein the control circuitry is further configured to perform cell detection based on the one or more DRS.

7. The arrangement of claim 1 , wherein the control circuitry is configured to perform cell detection using the same DRS used for the target cell measurement.

8. The arrangement of claim 1 , wherein the target cell measurement is based on a plurality of DRS measurements.

9. The arrangement of claim 1 , wherein the target cell measurement includes a signal to intereference plus noise ratio (SINR) estimated larger than a threshold amount, wherein the threshold amount is specified within the measurement configuration.

10. The arrangement of claim 1 , wherein the single shot comprises only one DRS of the one or more DRS used to generate the target cell measurement.

11. The arrangement of claim 1 , wherein the multi-shot comprises a plurality of DRS of the one or more DRS used to generate the target cell measurement.

12. The arrangement of claim 1 , wherein the control circuitry is to dynamically determine the measurement type between the multi-shot and the single shot based on one or more SINR estimates based on the one or more DRS.

13. The arrangement of claim 1 , wherein the DRS include primary synchronization signals (PSS) and secondary synchronization signals (SSS).

14. The arrangement of claim 1 , wherein the target cell measurement is based on reference signal-signal to noise and interference ratio (RS-SINR) measured by a cell specific reference signal (CRS) in the same DRS in LAA.

15. The arrangement of claim 1 , wherein the target cell measurement is based on primary synchronization signals (PSS) and secondary synchronization signals (SSS) of a single DRS of the one or more DRS.

16. An arrangement configured to be employed within an evolved Node B (eNodeB), the arrangement comprising:

control circuitry to:

generate a measurement configuration having a measurement type, measurement window, cell identification of a target cell and a DRS measurement timing configuration (DMTC), where the measurement configuration complies with license assisted access (LAA);

generate one or more discovery reference signals (DRS) during the measurement window;

enable a dynamic determination of whether to use a single shot or a multi-shot to request communication use of an unlicensed band; and

receive a measurement report having a target cell measurement for the target cell.

17. The arrangement of claim 16 , where the single shot specifies that the target cell measurement is based on a single DRS of the one or more DRS and the multi-shot specifies that the target cell measurement is based on a plurality of DRS of the one or more DRS.

18. The arrangement of claim 16 , wherein the one or more DRS include primary synchronization signals (PSS) and secondary synchronization signals (SSS).

19. The arrangement of claim 16 , wherein the measurement configuration includes a target cell threshold and the target cell measurement is greater than the target cell threshold.

20. A non-transitory computer-readable media having instructions that, when executed, cause one or more user equipment (UEs) to:

obtain a measurement configuration for a cell request using license assisted

access (LAA), wherein the measurement configuration includes a measurement window, cell identification and a measurement type;

receive one or more discovery reference signals (DRS) within the measurement window;

dynamically determine whether to use a single shot or a multi-shot based on a target cell measurement to request communication use of an unlicensed band; and

generate the target cell measurement based on the one or more DRS.

21. The non-transitory computer-readable media of claim 20 , comprising one or more computer-readable media having instructions that, when executed, further cause the one or more user equipment (UEs) to:

generate a measurement report having an indication whether the target cell measurement is greater than a threshold amount, wherein the threshold amount is specified in the measurement configuration.

22. The non-transitory computer-readable media of claim 20 , where the single shot specifies that the target cell measurement is based on a single DRS of the one or more DRS and the multi-shot specifies that the target cell measurement is based on a plurality of DRS of the one or more DRS.
