Abstract

A method in a network node for adapting a Secondary cell, SCell, command to a user equipment, UE, is provided. The SCell command is one of a setup and release command. The network node adapts the SCell command by one of advancing and delaying the timing of sending said SCell command with respect to a start of a transmission occasion of disjoint signals on which one of the UE and the network node is performing at least one of a measurement, the disjoint signal is a signal that is not used for performing the measurement in every subframe, a data transmission, the disjoint signal is a signal that is not used for transmitting the data in every subframe, and a data reception, the disjoint signal is a signal that is not used for receiving the data reception in every subframe.

Claims

1. A method in a User Equipment, UE, for adapting a Secondary Cell, SCell, setup or an SCell release, the UE being served by a network node, the method comprising:

receiving one of an SCell setup command and an SCell release command from the network node; and

adapting one of the SCell setup and the SCell release by delaying a time of applying the received one of the SCell setup command and the SCell release command to at least partly avoid a collision with a transmission of a disjoint signal on which the UE is performing a measurement, the disjoint signal being a signal that is not used for performing the measurement in every subframe.

2. The method according to claim 1, wherein the SCell setup is at least one of an SCell activation, an SCell deactivation, an SCell configuration and an SCell de-configuration.

3. The method according to claim 2, wherein the UE is required to meet a first set of pre-defined requirements related to the measurement performed on the disjoint signal when adapting the one of the SCell setup and the SCell release to avoid the collision.

4. The method according to claim 1, wherein the UE is required to meet a first set of pre-defined requirements related to the measurement performed on the disjoint signal when adapting the one of the SCell setup and the SCell release to avoid the collision.

5. The method according to claim 4, wherein the UE is required to meet a second set of pre-defined requirements related to the measurement performed on the disjoint signal when adapting the one of the SCell setup and the SCell release to partially avoid the collision.

6. The method according to claim 5, further comprising:

receiving from the network node, a network node'"'"'s capability to adaptively configure one of the SCell setup command and the SCell release command when the UE performs the measurement on the disjoint signal.

7. The method according to claim 1, wherein the UE is required to meet a second set of pre-defined requirements related to the measurement performed on the disjoint signal when adapting the one of SCell setup and release to partially avoid the collision.

8. The method according to claim 1, further comprising:

signaling to the network node, that the UE has a UE capability to adapt the one of the SCell setup and the SCell release of the SCell when the UE performs the measurement on the disjoint signal.

9. The method according to claim 8, further comprising:

receiving from the network node, a network node'"'"'s capability to adaptively configure one of the SCell setup command and the SCell release command when the UE performs the measurement on the disjoint signal.

10. The method according to claim 1, further comprising:

receiving from the network node, a network node'"'"'s capability to adaptively configure one of the SCell setup command and the SCell release command when the UE performs the measurement on the disjoint signal.

11. A User Equipment, UE, for adapting one of a Secondary Cell, SCell, setup and release, the UE being configured to be served by a network node, the UE comprising:

a communication circuitry configured to receive one of an SCell setup and release command from the network node; and

a processor configured to adapt one of an SCell setup and release by delaying a time of applying the received one of the SCell setup command and the SCell release command to at least partly avoid a collision with a disjoint signal on which the UE is performing a measurement, the disjoint signal being a signal that is not used for performing the measurement in every subframe.

12. The UE according to claim 11, wherein the SCell setup is at least one of an SCell activation, an SCell deactivation, an SCell configuration and an SCell de-configuration.

13. The UE according to claim 12, wherein the UE is configured to be required to meet a first set of pre-defined requirements related to the measurement performed on the disjoint signal when adapting the one of the SCell setup and the SCell release to avoid the collision.

14. The UE according to claim 11, wherein the UE is configured to be required to meet a first set of pre-defined requirements related to the measurement performed on the disjoint signal when adapting the one of the SCell setup and the SCell release to avoid the collision.

15. The UE according to claim 14, wherein the UE is configured to be required to meet a second set of pre-defined requirements related to the measurement performed on the disjoint signal adapting the one of the SCell setup and the SCell release to partially avoid the collision.

16. The UE according to claim 14, wherein the communication circuitry is further configured to signal to the network node that the UE has a UE capability to adapt the one of the SCell setup and the SCell release of the SCell when the UE performs the measurement on the disjoint signal.

17. The UE according to claim 16, wherein the communication circuitry is further configured to signal to the network node that the UE has a UE capability to adapt the one of the SCell setup and the SCell release of the SCell when the UE performs the measurement on the disjoint signal.

18. The UE according to claim 14, wherein the UE is configured to be required to meet a second set of pre-defined requirements related to the measurement performed on the disjoint signal adapting the one of the SCell setup and the SCell release to partially avoid the collision.

19. The UE according to claim 18, wherein the communication circuitry is further configured to signal to the network node that the UE has a UE capability to adapt the one of the SCell setup and the SCell release of the SCell when the UE performs the measurement on the disjoint signal.

20. The UE according to claim 11, wherein the communication circuitry is further configured to signal to the network node that the UE has a UE capability to adapt the one of the SCell setup and the SCell release of the SCell when the UE performs the measurement on the disjoint signal.
