Abstract

Disclosed is a system and method that allows a user equipment (UE) to perform a wireless measurement. The method configures a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE. Also disclosed is a system and method to perform radio resource management (RRM) testing. Testing can include: setting a power level of CSI-RS for tracking to a smaller value that a power level of another RRM reference signal; or setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal; or setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

Claims (39)

1. A method allowing a user equipment (UE) to perform a wireless measurement, comprising:

configuring a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE by setting:

a power level of the CSI-RS for tracking to a value smaller than a power level characteristic of a radio resource management (RRM) reference signal,

wherein the RRM reference signal includes one of an RRM measurement signal, a radio link monitoring (RLM) signal, a beam failure detection (BFD) signal, a candidate beam detection (CBD) signal, or a beam reporting (BR) testing signal; and

performing a wireless measurement using the CSI-RS.

2. The method of claim 1 , further comprising setting a first power level of the BR testing signal to determine a power level of a level-1 reference signal received power (RSRP) measurement reporting signal.

3. The method of claim 1 , further comprising setting more than one characteristic of the CSI-RS for tracking.

4. The method of claim 1 , further comprising:

setting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal, or

setting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

5. The method of claim 4 , further comprising setting the positive power offset value such that the PDSCH has a higher energy per resource element (EPRE) than an EPRE of the CSI-RS for tracking.

6. The method of claim 4 , wherein the CSI-RS for tracking is configured to have a longer periodicity than an SS periodicity or a synchronization signal block (SSB)-based measurement timing configuration periodicity.

7. The method of claim 4 , further comprising setting the negative power offset value such that the SS has a higher energy per resource element (EPRE) than an EPRE of the CSI-RS for tracking.

8. A user equipment (UE) comprising:

radio front end circuitry; and

processing circuitry coupled to the radio front end circuitry, wherein the processing circuitry configures a characteristic of a channel-state information reference signal (CSI-RS) for adjusting a radio resource management (RRM) reference signal by setting:

a power level of the CSI-RS for tracking to a value smaller than a power level characteristic of the RRM reference signal,

wherein the RRM reference signal includes one of an RRM measurement signal, a radio link monitoring (RLM) signal, a beam failure detection (BFD) signal, a candidate beam detection (CBD) signal, or a beam reporting (BR) testing signal; and

wherein the processing circuitry performs a wireless measurement using the CSI-RS.

9. The UE of claim 8 , wherein the processing circuitry is further configured to set a power level of the BR testing signal to determine a power level of a level-1 reference signal received power (RSRP) measurement reporting signal.

10. The UE of claim 8 , further comprising setting more than one characteristic of the CSI-RS for tracking.

11. The UE of claim 8 , wherein the processing circuitry configures the characteristic of the CSI-RS by setting:

a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal, or

a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

12. The UE of claim 11 , wherein the processing circuitry is further configured to set the positive power offset value such that the PDSCH has a higher energy per resource element (EPRE) than an EPRE of the CSI-RS for tracking.

13. The UE of claim 11 , wherein the CSI-RS for tracking is configured to have a longer periodicity than an SS periodicity or a synchronization signal block (SSB)-based measurement timing configuration periodicity.

14. The UE of claim 11 , wherein the processing circuitry is further configured to set the negative power offset value such that the SS has a higher energy per resource element (EPRE) than an EPRE of the CSI-RS for tracking.

15. A non-transitory computer-readable device for allowing a user equipment (UE) to perform a wireless measurement, the non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

configuring a characteristic of a channel-state information reference signal (CSI-RS) for tracking of the UE by setting:

a power level of the CSI-RS for tracking to a value smaller than a power level characteristic of a radio resource management (RRM) reference signal,

wherein the RRM reference signal includes one of an RRM measurement signal, a radio link monitoring (RLM) signal, a beam failure detection (BFD) signal, a candidate beam detection (CBD) signal, or a beam reporting (BR) testing signal; and

performing a wireless measurement using the CSI-RS.

16. The non-transitory computer-readable device of claim 15 , the operations further comprising settting a first power level of the BR testing signal to a power level of a level-1 reference signal received power (RSRP) measurement reporting signal.

17. The non-transitory computer-readable device of claim 15 , the operations further comprising settting more than one characteristic of the CSI-RS for tracking.

18. The non-transitory computer-readable device of claim 15 , the operations further comprising:

settting a negative power offset value of the CSI-RS for tracking to a synchronization signal (SS) of the RRM reference signal, or

settting a positive power offset value of the CSI-RS for tracking to a physical downlink shared channel (PDSCH) of the RRM reference signal.

19. The non-transitory computer-readable device of claim 18 , the operations further comprising settting the positive power offset value such that a physical downlink shared channel (PDSCH) has a higher energy per resource element (EPRE) than an EPRE of the CSI-RS for tracking.

20. The non-transitory computer-readable device of claim 18 , the operations further comprising settting the CSI-RS for tracking to have a longer periodicity than an SS periodicity or a synchronization signal block (SSB)-based measurement timing configuration periodicity.
