Fallback conditional handover configuration with single connectivity

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 at least:

determine that a conditional handover condition is met;

based upon the determining that the conditional handover condition is met and based, at least partially, on a priority information, select a conditional handover configuration from at least one conditional handover configuration to perform a conditional handover to a primary secondary cell;

prioritize a different conditional handover configuration while a primary secondary cell access condition is running and has not been met;

execute the different conditional handover configuration after the primary secondary cell access condition is met; and

receive, from a network entity, a plurality of conditional handover conditions;

where the priority information is indicated as being dependent upon at least one parameter;

the at least one parameter comprises when primary secondary cell access condition determination is running, and the primary secondary cell access condition has not been met; and

the determining that the conditional handover condition is met is based upon at least one of the received plurality of conditional handover conditions.

2 . The apparatus as claimed in claim 1 where the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least:

receive handover information from a network entity, where the handover information comprises one or more of conditional handover configuration information, measurement configuration information and conditional handover priority information, where the conditional handover priority information comprises the priority information.

3 . The apparatus as claimed in claim 2 where the conditional handover priority information comprises information indicating that priority is to be given to a first conditional handover configuration relative to a second conditional handover configuration.

4 . The apparatus as claimed in claim 1 where the priority information comprises priority information pre-configured in the apparatus.

5 . The apparatus as claimed in claim 1 where the at least one parameter comprises when only a conditional handover condition 1 holds.

6 . The apparatus as claimed in claim 1 where the at least one parameter comprises when only a primary serving cell condition holds.

7 . The apparatus as claimed in claim 1 where the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least:

prioritize single connectivity if a primary serving cell condition is present.

8 . The apparatus as claimed in claim 1 where the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least:

select a first one of at least two conditional handover configurations, with the first conditional handover configuration being prioritized over other one(s) of the at least two conditional handover configurations, when the primary secondary cell access condition is running in the apparatus.

9 . The apparatus as claimed in claim 8 where the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least:

select and execute the first conditional handover or a different one of the at least two conditional handover configurations based upon the priority information and when the primary secondary cell condition is met.

10 . The apparatus as claimed in claim 1 , where the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least:

provide a capability indication to a network node, indicating to support conditional handover which includes priority information.

11 . A method comprising:

determining that a conditional handover condition is met by a user equipment;

based upon the determining that the conditional handover condition is met and based, at least partially, on a priority information, selecting by the user equipment a conditional handover configuration from at least one conditional handover configuration to perform a conditional handover to a primary secondary cell;

prioritizing a different conditional handover configuration while the primary secondary cell access condition is running and has not been met;

executing the different conditional handover configuration after the primary secondary cell condition is met; and

receiving, from a network entity, a plurality of conditional handover conditions;

where the priority information is indicated as being dependent upon at least one parameter;

the at least one parameter comprises when primary secondary cell access condition determination is running, and the primary secondary cell access condition has not been met; and

the determining that the conditional handover condition is met is based upon at least one of the received plurality of conditional handover conditions.

12 . The method as claimed in claim 11 further comprising receiving handover information from a network entity, where the handover information comprises one or more of conditional handover configuration information, measurement configuration information and conditional handover priority information, where the conditional handover priority information comprises the priority information.

13 . The method as claimed in claim 12 where the conditional handover priority information comprises information indicating that priority is to be given to a first conditional handover configuration relative to a second conditional handover configuration.

14 . The method as claimed in claim 11 where the priority information comprises priority information pre-configured in the user equipment.

15 . A non-transitory program storage device readable by an apparatus, tangibly embodying a program of instructions executable with the apparatus for performing operations, the operations comprising:

determining that a conditional handover condition is met;

based upon the determining that the conditional handover condition is met and based, at least partially, on a priority information, selecting a conditional handover configuration from at least one conditional handover configuration to perform a conditional handover to a primary secondary cell;

prioritizing a different conditional handover configuration while the primary secondary cell access condition is running and has not been met;

executing the different conditional handover configuration after the primary secondary cell condition is met; and

receiving, from a network entity, a plurality of conditional handover conditions:

where the priority information is indicated as being dependent upon at least one parameter;

the at least one parameter comprises when primary secondary cell access condition determination is running, and the primary secondary cell access condition has not been met; and

the determining that the conditional handover condition is met is based upon at least one of the received plurality of conditional handover conditions.

16 . The non-transitory program storage device as claimed in claim 15 where the operations further comprise receiving handover information from a network entity, where the handover information comprises one or more of conditional handover configuration information, measurement configuration information and conditional handover priority information, where the conditional handover priority information comprises the priority information.

17 . The non-transitory program storage device as claimed in claim 16 where the conditional handover priority information comprises information indicating that priority is to be given to a first conditional handover configuration relative to a second conditional handover configuration.

18 . The non-transitory program storage device as claimed in claim 15 where the priority information comprises priority information pre-configured in the apparatus.
