CLAIMS

What is claimed is:

1. A method of wireless communications, comprising:

receiving, by a user equipment (UE), a message including information of a configuration, wherein the configuration includes at least a group of repetitions of one or more synchronization signal (SS) blocks in an SS burst set, wherein the repetitions of the one or more SS blocks are configured into at least two groups; and

determining, by the UE, which group of the at least two groups to search for during a synchronous neighbor cell search based on the information and at least one condition at the UE.

2. The method of claim 1, further comprising:

performing, by the UE, the synchronous neighbor cell search in response to the determination.

3. The method of claim 1, wherein the at least two groups are configured based on different beam widths.

4. The method of claim 1, wherein the at least two groups include:

a first group having one or more beams with broad beam width and low beamforming gain, and

a second group having one or more beams with narrow beam width and high beamforming gain.

5. The method of claim 1, wherein the message is at least one of a master information block (MIB), a master system information block (mSIB), a system information block (SIB), a radio resource control (RRC) message, a medium access control (MAC) control element (CE), or a downlink control information (DCI) message.

6. The method of claim 1 , wherein the at least one condition is a battery level or power budget at the UE.

7. The method of claim 1, further comprising:

sending, by the UE, one or more metrics to assist configuring the at least two groups or to indicate which group of the at least two groups to search for.

8. The method of claim 7, wherein the one or more metrics include at least one of a battery level of the UE, a function of search parameters, or an indication of preferred group, group size, or an SS block repetition pattern.

9. The method of claim 1, wherein each of the at least two groups is configured based on an angular coverage.

10. The method of claim 1, wherein each of the at least two groups is divided into multiple subgroups, wherein each subgroup covers a particular angular spread of a cell.

11. The method of claim 10, wherein the information includes a restriction to one of the multiple subgroups based on an estimation at a base station or the at least one condition at the UE.

12. The method of claim 11, wherein the estimation is based on one or more UE reports, and wherein the one or more UE reports include a UE positioning report, a UE orientation report, or a UE mobility report.

13. A user equipment (UE) for wireless communications, comprising:

a receiver;

a memory configured to store instructions; and

at least one processor communicatively coupled with the receiver and the memory, wherein the at least one processor is configured to execute the instructions to: receive, via the receiver, a message including information of a configuration, wherein the configuration includes at least a group of repetitions of one or more synchronization signal (SS) blocks in an SS burst set, wherein the repetitions of SS blocks in the SS burst set are configured into at least two groups; and

determine which group of the at least two groups to search for during a synchronous neighbor cell search based on the configuration and at least one condition at the UE.

14. The UE of claim 13, wherein the at least one processor is further configured to perform the synchronous neighbor cell search in response to the determination.

15. The UE of claim 13, wherein the at least two groups are configured based on different beam widths.

16. The UE of claim 13, wherein the at least two groups include:

a first group having one or more beams with broad beam width and low beamforming gain; and

a second group having one or more beams with narrow beam width and high beamforming gain.

17. The UE of claim 13, wherein the at least one condition is a battery level or power budget of the UE.

18. The UE of claim 13, wherein each of the at least two groups is configured based on an angular coverage.

19. A user equipment (UE) for wireless communications, comprising:

means for receiving a message including information of a configuration, wherein the configuration includes at least a group of repetitions of one or more synchronization signal (SS) blocks in an SS burst set, wherein the repetitions of the one or more SS blocks are configured into at least two groups; and

means for determining which group of the at least two groups to search for during a synchronous neighbor cell search based on the information and at least one condition at the UE.

20. The UE of claim 19, further comprising:

means for performing the synchronous neighbor cell search in response to the determination.

21. The UE of claim 19, wherein the at least two groups include:

a first group having one or more beams with broad beam width and low beamforming gain; and

a second group having one or more beams with narrow beam width and high beamforming gain.

22. A method of wireless communications, comprising:

configuring, by a base station, repetitions of one or more synchronization signal (SS) blocks in an SS burst set into at least two groups; and

sending, by the base station to a user equipment (UE), a message including information of the configuration.

23. The method of claim 22, wherein the at least two groups are configured based on different beam widths.

24. The method of claim 22, wherein the information indicates which group of the at least two groups to search for during a synchronous neighbor cell search by the UE.

25. The method of claim 22, further comprising:

receiving, by the base station, one or more metrics to assist configuring the at least two groups or to indicate which group of the at least two groups to search for by the UE.

26. The method of claim 25, wherein the one or more metrics include at least one of a battery level of the UE, a function of search parameters, or an indication of preferred group, group size, or an SS block repetition pattern.

27. The method of claim 22, wherein each of the at least two groups is configured based on an angular coverage and is divided into multiple subgroups, wherein each subgroup covers a particular angular spread of a cell, and wherein the information includes a restriction to one of the multiple subgroups based on an estimation at the base station or a battery level at the UE.

28. The method of claim 22, wherein the at least two groups include:

a first group having one or more beams with broad beam width and low beamforming gain; and

a second group having one or more beams with narrow beam width and high beamforming gain.

29. The method of claim 22, wherein each of the at least two groups is configured based on an angular coverage.

30. The method of claim 22, wherein each of the at least two groups is divided into multiple subgroups, wherein each subgroup covers a particular angular spread of a cell.
