Abstract

A system, method, and apparatus is provided for performing testing using arrival of angles (AOA). The system, method, and apparatus can receive a first test signal from a first cell; receive a second test signal from a second cell; and perform a test based on AOA of the first test signal and the second test signal. At least one of the first test signal and the second test signal can include a channel state information-reference signal (CSI-RS) signal or a synchronization signal block (SSB) signal. The first test signal can include a different number of SSBs transmitted during an Measurement Timing Configuration (MTC) window when compared to the second test signal. The system, method, and apparatus can receive the first test signal and the second test signal in a time division multiple access (TDMA) manner. The first cell can include a serving cell and the second cell can include a neighboring cell of the serving cell. The system, method, and apparatus can receive the first test signal using a main lobe of an antenna and the second test signal using a side lobe of the antenna.

First claim

What is claimed is:

receiving a first test signal from a first cell;
receiving a second test signal from a second cell; and
performing a test based on an AOA of the first test signal and an AOA of the second test signal,
wherein the first test signal comprises a different number of Synchronization Signal Blocks (SSBs) transmitted during a Measurement Timing Configuration (MTC) window when compared to the second test signal.

2. The method of claim 1 , wherein at least one of the first test signal and the second test signal comprises a channel state information-reference signal (CSI-RS) signal.

3. The method of claim 1 , wherein the second test signal comprises an SSB signal.

4. The method of claim 1 , wherein the first test signal and the second test signal are received in a time division multiple access (TDMA) manner.

5. The method of claim 1 , wherein the first cell comprises a serving cell, and
wherein the second cell comprises a neighboring cell of the serving cell.

6. The method of claim 1 , wherein the receiving the first test signal comprises:
receiving the first test signal using a main lobe of an antenna, and
wherein the receiving the second test signal comprises:
receiving the second test signal using a side lobe of the antenna.

7. The method of claim 1 , wherein an SSB received from the first cell is located at a different position in the MTC window than an SSB received from the second cell.

8. A user equipment (UE), comprising:
radio front end circuitry configured to receive a first test signal from a first cell and a second test signal from a second cell; and
processing circuitry configured to perform a test based on an angle of arrival (AOA) of the first test signal and an AOA of the second test signal,
wherein the first test signal comprises a different number of Synchronization Signal Blocks (SSBs) transmitted during a Measurement Timing Configuration (MTC) window when compared to the second test signal.

9. The UE of claim 8 , wherein at least one of the first test signal and the second test signal comprises a channel state information-reference signal (CSI-RS) signal.

10. The UE of claim 8 , wherein the second test signal comprises an SSB signal.

11. The UE of claim 8 , wherein the first test signal and the second test signal are received in a time division multiple access (TDMA) manner.

12. The UE of claim 8 , wherein the first cell comprises a serving cell, and
wherein the second cell comprises a neighboring cell of the serving cell.

13. The UE of claim 8 , wherein the radio front end circuitry is configured to:
receive the first test signal using a main lobe of an antenna, and
receive the second test signal using a side lobe of the antenna.

14. The UE of claim 8 , wherein an SSB received from the first cell is located at a different position in the MTC window than an SSB received from the second cell.

15. A system for performing testing using arrival of angles (AOAs), the system comprising:
a first probe within a first cell;
a second probe within a second cell; and
a User Equipment (UE) configured to:
receive a first test signal from the first probe and a second test signal from the second probe, and
perform a test based on an AOA of the first test signal and an AOA of the second test signal,

wherein the first test signal comprises a different number of Synchronization Signal Blocks (SSBs) transmitted during a Measurement Timing Configuration (MTC) window when compared to the second test signal.

16. The system of claim 15 , wherein at least one of the first test signal and the second test signal comprises a channel state information-reference signal (CSI-RS) signal.

17. The system of claim 15 , wherein the second test signal comprises an SSB signal.

18. The system of claim 15 , wherein the first test signal and the second test signal are received in a time division multiple access (TDMA) manner.

19. The system of claim 15 , wherein the first cell comprises a serving cell, and
wherein the second cell comprises a neighboring cell of the serving cell.

20. The system of claim 15 , wherein an SSB received from the first cell is located at a different position in the MTC window than an SSB received from the second cell.
