Abstract

Technology for a user equipment (UE) operable to perform measurements for measurement objects (MOs) in a New Radio (NR) system is disclosed. The UE can identify an MO configured by an NR network in the NR system, wherein the MO is associated with a synchronization signal block (SSB) of a frequency. The UE can measure the MO associated with the SSB for the frequency. The UE can encode a measurement report for transmission to the NR network, wherein the measurement report includes one or more measurements associated with the MO.

First claim

What is claimed is:

1. An apparatus of a user equipment (UE) operable to perform measurements for measurement objects (MOs) in a New Radio (NR) system, the UE comprising:
one or more processors configured to:
identify, at the UE, an MO configured by an NR network in the NR system, wherein the MO is associated with a synchronization signal block (SSB) of a frequency;
measure, at the UE, the MO associated with the SSB for the frequency; and
encode, at the UE, a measurement report for transmission to the NR network, wherein the measurement report includes one or more measurements associated with the MO; and
a memory interface configured to send to a memory a configuration of the MO.

2. The apparatus of claim 1 , further comprising a transceiver configured to receive the configuration of the MO from the NR network.

3. The apparatus of claim 1 , wherein the one or more processors are configured to identify the MO from multiple MOs that are configured by the NR network in the NR system, wherein the multiple MOs are associated with multiple SSBs on separate bandwidth parts (BWPs) of the frequency.

4. The apparatus of claim 3 , wherein the one or more processors are configured to measure the MO associated with an active BWP of the separate BWPs of the frequency.

5. The apparatus of claim 3 , wherein the one or more processors are configured to select a BWP of the separate BWPs on the frequency to measure when no MO included in the multiple MOs is associated with an active BWP.

6. The apparatus of claim 1 , wherein the SSB is a cell defining SSB.

7. The apparatus of claim 1 , wherein the frequency is a serving frequency or a non-serving frequency.

8. The apparatus of claim 1 , wherein the MO is a single MO that is configured for one frequency.

9. The apparatus of claim 1 , wherein the SSB is used as a timing reference by the UE for a channel state information reference signal (CSI-RS).

10. An apparatus of a New Radio (NR) network operable to decode measurements for measurement objects (MOs) received from a user equipment (UE), the NR network comprising:
one or more processors configured to:
configure, at the NR network, an MO for the UE, wherein the MO is associated with a synchronization signal block (SSB) of a frequency; and
decode, at the NR network, a measurement report received from the UE, wherein the measurement report includes one or more measurements for the MO associated with the SSB for the frequency; and
a memory interface configured to send to a memory the measurement report.

11. The apparatus of claim 10 , further comprising a transceiver configured to:
transmit a configuration of the MO to the UE; and
receive the measurement report from the UE.

12. The apparatus of claim 10 , wherein the MO is one of multiple MOs that are configured by the NR network, wherein the multiple MOs are associated with multiple SSBs on separate bandwidth parts (BWPs) of the frequency.

13. The apparatus of claim 12 , wherein the MO associated with an active BWP of the separate BWPs of the frequency is measured at the UE.

14. The apparatus of claim 12 , wherein a BWP of the separate BWPs on the frequency is selected to measure at the UE when no MO included in the multiple MOs is associated with an active BWP.

15. The apparatus of claim 10 , wherein the SSB is a cell defining SSB.

16. The apparatus of claim 10 , wherein the frequency is a serving frequency or a non-serving frequency.

17. The apparatus of claim 10 , wherein the MO is a single MO that is configured for one frequency.

18. The apparatus of claim 10 , wherein the SSB is used as a timing reference by the UE for a channel state information reference signal (CSI-RS).

19. At least one non-transitory machine readable storage medium having instructions embodied thereon for performing measurements for measurement objects (MOs) in a New Radio (NR) system, the instructions when executed by one or more processors at a user equipment (UE) perform the following:
identifying, at the UE, an MO configured by an NR network in the NR system, wherein the MO is associated with a synchronization signal block (SSB) of a frequency;
measuring, at the UE, the MO associated with the SSB for the frequency; and
encoding, at the UE, a measurement report for transmission to the NR network, wherein the measurement report includes one or more measurements associated with the MO.

20. The at least one non-transitory machine readable storage medium of claim 19 , further comprising instructions when executed perform the following: identifying the MO from multiple MOs that are configured by the NR network in the NR system, wherein the multiple MOs are associated with multiple SSBs on separate bandwidth parts (BWPs) of the frequency.

21. The at least one non-transitory machine readable storage medium of claim 20 , further comprising instructions when executed perform the following: measuring the MO associated with an active BWP of the separate BWPs of the frequency.

22. The at least one non-transitory machine readable storage medium of claim 20 , further comprising instructions when executed perform the following: selecting a BWP of the separate BWPs on the frequency to measure when no MO included in the multiple MOs is associated with an active BWP.

23. The at least one non-transitory machine readable storage medium of claim 19 , wherein the frequency is a serving frequency or a non-serving frequency.

24. The at least one non-transitory machine readable storage medium of claim 19 , wherein the MO is a single MO that is configured for one frequency.

25. An apparatus of a user equipment (UE) operable to encode a measurement report for transmission to a New Radio (NR) base station, the UE comprising:
one or more processors configured to:
determine, at the UE, one or more NR cells that have K beams that are above a first defined threshold, wherein K is a positive integer;
determine, at the UE, M NR cells that have an increased number of beams measured above a second defined threshold, wherein M is a positive integer; and
encode, at the UE, a measurement report for transmission to the NR base station that includes measurements for the one or more NR cells that have K beams that are above the first defined threshold or the M NR cells that have the increased number of beams measured above the second defined threshold,
