Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a mode in which the user equipment is enabled, wherein the mode is one of a non-standalone mode, a standalone mode, or a standalone mode and a non-standalone mode; determine whether to prioritize a first set of frequencies associated with a first radio access technology (RAT) or a second set of frequencies associated with a second RAT based at least in part on the mode in which the user equipment is enabled, wherein the first RAT is different from the second RAT; and perform a search of the first set of frequencies or the second set of frequencies based at least in part on whether the first set of frequencies or the second set of frequencies is prioritized. Numerous other aspects are provided.

First claim

What is claimed is:

1. A method of wireless communication performed by a user equipment, comprising:
determining a mode in which the user equipment is enabled,
wherein the mode is one of a non-standalone mode, a standalone mode, or a standalone mode and a non-standalone mode;

determining whether to prioritize a first set of frequencies associated with a first radio access technology (RAT) or a second set of frequencies associated with a second RAT based at least in part on the mode in which the user equipment is enabled,
wherein the first RAT is different from the second RAT,
wherein the first RAT is a Long Term Evolution RAT, and
wherein the second RAT is a New Radio RAT;

performing a search of the first set of frequencies or the second set of frequencies based at least in part on whether the first set of frequencies or the second set of frequencies is prioritized; and
providing, by the user equipment and for display, information that indicates that a particular cell, of a set of cells identified in the search, is a associated with the New Radio RAT based at least in part on the user equipment being enabled for one of the non-standalone mode, the standalone mode, or the non-standalone mode and the standalone mode.

2. The method of claim 1 , wherein the search is performed for the first set of frequencies and not the second set of frequencies based at least in part on the user equipment being enabled for the non-standalone mode.

3. The method of claim 1 , wherein the search is performed for the first set of frequencies and the second set of frequencies based at least in part on the user equipment being enabled for the non-standalone mode and the standalone mode.

4. The method of claim 1 , wherein the search is performed for the first set of frequencies before the second set of frequencies based at least in part on the user equipment being enabled for the standalone mode.

5. The method of claim 1 , further comprising:
providing, for display, information that indicates whether the set of cells are associated with the first RAT or the second RAT.

6. The method of claim 1 , further comprising:
providing, for display, information that indicates one or more cellular providers associated with the set of cells.

7. The method of claim 1 , further comprising:
providing, for display, information identifying the set of cells,
wherein the information is provided in a particular order based at least in part on the mode in which the user equipment is enabled or a possible mode in which the user equipment can be enabled.

8. The method of claim 1 ,
wherein the user equipment is enabled for the non-standalone mode, and
wherein providing the information that indicates that the particular cell is associated with the New Radio RAT comprises:
providing the information that indicates that the particular cell is an LTE cell that is associated with the NEW Radio RAT based at least in part on the user equipment being enabled for the non-standalone mode.

9. The method of claim 1 ,
wherein the user equipment is enabled for the non-standalone mode and the standalone mode,
wherein a particular cell of the set of cells is at least one of:
a Long Term Evolution cell that uses the New Radio RAT, or
a New Radio cell, and

wherein providing the information that indicates that the particular cell is associated with the New Radio RAT comprises:
providing, for display, the information that indicates that the particular cell is associated with the New Radio RAT based at least in part on the user equipment being enabled for the non-standalone mode and the standalone mode.

10. The method of claim 1 , wherein the user equipment is enabled for the standalone mode, and
wherein providing the information that indicates that the particular cell is associated with the New Radio RAT comprises:
providing, for display, information that indicates that the particular cell is associated with the New Radio RAT based at least in part on the user equipment being enabled for the standalone mode.

11. The method of claim 1 , further comprising:
selecting the particular cell, from the set of cells based at least in part on whether the particular cell is a cell of the first RAT or a cell of the second RAT and further based at least in part on a mobile network associated with the particular cell.

12. The method of claim 1 , wherein the particular cell is selected based at least in part on whether the user equipment is enabled for the non-standalone mode, the standalone mode, or the standalone mode and the non-standalone mode.

13. The method of claim 1 , wherein the user equipment is enabled for the non-standalone mode, and
wherein the particular cell is selected based at least in part on the particular cell being a Long Term Evolution cell that is associated with the New Radio RAT.

14. The method of claim 1 , wherein the user equipment is enabled for the non-standalone mode and the standalone mode, and
wherein the particular cell is selected based at least in part on the particular cell being at least one of:
a Long Term Evolution cell that is associated with the New Radio RAT, or
a New Radio cell.

15. The method of claim 11 , wherein user equipment is enabled for the standalone mode, and
wherein the particular cell is selected based at least in part on the particular cell being a New Radio cell.

16. The method of claim 1 , wherein the search is a better Public Land Mobile Network (BPLMN) search.

17. A user equipment for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
determine a mode in which the user equipment is enabled,
wherein the mode is one of a non-standalone mode, a standalone mode, or a standalone mode and a non-standalone mode;

determine whether to prioritize a first set of frequencies associated with a first radio access technology (RAT) or a second set of frequencies associated with a second RAT based at least in part on the mode in which the user equipment is enabled,
wherein the first RAT is different from the second RAT,
wherein the first RAT is a Long Term Evolution RAT, and
wherein the second RAT is a New Radio RAT;

perform a search of the first set of frequencies or the second set of frequencies based at least in part on whether the first set of frequencies or the second set of frequencies is prioritized; and
provide, by the user equipment and for display, information that indicates that a particular cell, of a set of cells identified in the search, is associated with the New Radio RAT based at least in part on the user equipment being enabled for one of the non-standalone mode, the standalone mode, or the non-standalone mode and the standalone mode.

18. The user equipment of claim 17 , wherein the search is performed for the first set of frequencies and not the second set of frequencies based at least in part on the user equipment being enabled for the non-standalone mode.

19. The user equipment of claim 17 , wherein the search is performed for the first set of frequencies and the second set of frequencies based at least in part on the user equipment being enabled for the non-standalone mode and the standalone mode.

20. The user equipment of claim 17 , wherein the search is performed for the first set of frequencies before the second set of frequencies based at least in part on the user equipment being enabled for the standalone mode.
