Abstract

An apparatus including at least one processor; and at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform: receiving a combined information, where the combined information includes first information regarding inter-cell beam management and second information regarding lower layer mobility; using the second information to initiate a handover of the apparatus from a first cell to a second cell; and using the first information to provide communication of the apparatus with another cell at least partially during the handover to the second cell, where the another cell includes the first cell or a third cell.

First claim

What is claimed is:

1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
receiving a combined information, where the combined information comprises first information regarding inter-cell beam management and second information regarding lower layer mobility;
using the second information to initiate a handover of the apparatus from a first cell to a second cell; and
using the first information to provide communication of the apparatus with another cell at least partially during the handover to the second cell, where the another cell comprises the first cell or a third cell.

2. The apparatus as claimed in claim 1 where the instructions, when executed with the at least one processor, cause the apparatus to perform:
receiving of an indication to trigger use of both the first information and the second information to provide the communication of the apparatus with the another cell at least partially during the handover to the second cell.

3. A method comprising:
receiving with an apparatus a combined information, where the combined information comprises first information regarding inter-cell beam management and second information regarding lower layer mobility;
using the second information to initiate a handover of the apparatus from a first cell to a second cell; and
using the first information to provide communication of the apparatus with another cell at least partially during the handover to the second cell, where the another cell comprises the first cell or a third cell.

4. The method as in claim 3 further comprising receiving, with the apparatus, an indication to trigger use of both the first information and the second information to provide the communication of the apparatus with the another cell at least partially during the handover to the second cell.

5. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
determining to add first information regarding inter-cell beam management with second information regarding lower layer mobility;
based upon the determining to add the first information with the second information, sending the first information and the second information together to a network entity.

6. The apparatus as claimed in claim 5 where the second information is in regard to a handover from a first cell to a second cell, and where the inter-cell beam management is in regard to the first cell or a third cell.

7. The apparatus as claimed in claim 6 where the third cell is at least partially controlled with the apparatus.

8. The apparatus as claimed in claim 6 where the third cell is at least partially controlled with a different apparatus, and where the different apparatus comprises a source distributed unit (DU), or a target distributed unit (DU), or a third distributed unit (DU) which is different from the source distributed unit and the target distributed unit.

9. The apparatus as claimed in claim 5 where the apparatus comprises a serving distributed unit (DU) at least partially controlling a first cell and a second cell, and where the second information is in regard to a handover from the first cell to the second cell.

10. The apparatus as claimed in claim 9 where the first information is in regard to communication of a user equipment with another cell at least partially during the handover of the user equipment to the second cell, where the another cell comprises the first cell or a third cell.

11. The apparatus as claimed in claim 5 where the apparatus comprises a target distributed unit (DU) at least partially controlling a second cell, and where the second information is in regard to a handover from a first cell to the second cell, where the first cell is controlled at least partially with a serving distributed unit (DU).

12. The apparatus as claimed in claim 11 where the inter-cell beam management is in regard to a third cell, where the third cell is:
at least partially controlled with the target distributed unit (DU), or
at least partially controlled with another target distributed unit (DU).

13. The apparatus as claimed in claim 5 where the instructions, when executed with the at least one processor, cause the apparatus to perform:
receiving beam information from a user equipment;
based, at least partially, upon the receiving of the beam information from the user equipment, determining to trigger the lower layer mobility with the inter-cell beam management.

14. The apparatus as claimed in claim 13 where the instructions, when executed with the at least one processor, cause the apparatus to perform:
sending, based upon the determining to trigger the lower layer mobility with the inter-cell beam management, a signal to the user equipment, to cause the user equipment to initiate a handover of the user equipment from a first cell to a second cell, and cause the user equipment to provide inter-cell beam management communication of the user equipment with another cell during handover to the second cell.

15. The apparatus as claimed in claim 13 where the another cell is the first cell or a third cell.

16. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
receiving beam information from a user equipment;
based, at least partially, upon the receiving of the beam information from the user equipment, determining to add first information for inter-cell beam management with second information for lower layer mobility; and
sending the first and second information as mobility information to the user equipment, where the mobility information is configured to, at least partially, enable the user equipment to initiate a handover of the user equipment from a first cell to a second cell, and enable the user equipment to provide communication of the user equipment with another cell during handover to the second cell.

17. The apparatus as claimed in claim 16 where the another cell comprises the first cell or a third cell.

18. The apparatus as claimed in claim 16 where the mobility information comprises indicating a transmission configuration indicator (TCI) state of the another cell to be used during execution of the handover.

19. The apparatus as claimed in claim 16 where the apparatus is a serving distributed unit (DU), where the serving distributed unit at least partially controls the first cell, and where the another cell comprises a third cell.

20. The apparatus as claimed in claim 19 where the third cell is at least partially controlled with a target distributed unit (DU).

21. The apparatus as claimed in claim 20 where the second cell is at least partially controlled with the target distributed unit (DU).

22. The apparatus as claimed in claim 20 where the second cell is at least partially controlled with another target distributed unit (DU).

23. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
receiving, from a network entity, first information for inter-cell beam management and second information for lower layer mobility; and
determining, based upon the receiving of the first information for in
