Abstract

A method for wireless communication by a user equipment (UE) includes receiving an indication of a mobility configured cell set having a number of cells. The method also includes receiving signaling to release a selected cell from the mobility configured cell set. The method further includes releasing the selected cell from the mobility configured cell set in response to receiving the signaling. In some aspects, releasing the selected cell comprises removing the selected cell from a carrier aggregation configuration. In other aspects, releasing the selected cell comprises removing a mobility configuration for the selected cell.

Claims (46)

1. A method of wireless communication by a user equipment (UE), comprising:

receiving an indication of a mobility configured cell set comprising a plurality of cells;

receiving signaling to release a selected cell of the plurality of cells from the mobility configured cell set; and

releasing the selected cell from the mobility configured cell set in response to receiving the signaling wherein the signaling comprises a media access control-control element (MAC-CE) having a first octet indicating release of the selected cell from the mobility configured cell set, and a second octet indicating removal of a mobility configuration for the selected cell.

2. The method of claim 1 , in which releasing the selected cell comprises removing the selected cell from a carrier aggregation configuration.

3. The method of claim 1 , in which releasing the selected cell comprises removing a mobility configuration for the selected cell.

4. The method of claim 1 , in which the signaling comprises layer one (L1) signaling.

5. The method of claim 1 , in which the signaling comprises layer two (L2) signaling.

6. The method of claim 1 , in which the indication is a radio resource control (RRC) configuration.

7. The method of claim 1 , in which the mobility configured cell set has a configuration identifying one or more primary cell configurations for each secondary cell in the configured cell set, one or more secondary cell configurations for each primary cell in the configured cell set, and a measurement configuration for each cell in the configured cell set.

8. A method of wireless communication by a network entity, comprising:

transmitting an indication of a mobility configured cell set comprising a plurality of cells;

transmitting signaling to release a selected cell of the plurality of cells from the mobility configured cell set; and

releasing the selected cell from the mobility configured cell set in response to transmitting the signaling, in which the signaling comprises a media access control-control element (MAC-CE) having a first octet indicating release of the selected cell from the mobility configured cell set, and a second octet indicating removal of a mobility configuration for the selected cell.

9. The method of claim 8 , in which releasing the selected cell comprises removing the selected cell from a carrier aggregation configuration.

10. The method of claim 8 , in which releasing the selected cell comprises removing a mobility configuration for the selected cell.

11. The method of claim 8 , in which the signaling comprises layer one (L1) signaling.

12. The method of claim 8 , in which the signaling comprises layer two (L2) signaling.

13. The method of claim 8 , in which the indication is a radio resource control (RRC) configuration.

14. The method of claim 8 , in which the mobility configured cell set has a configuration identifying one or more primary cell configurations for each secondary cell in the configured cell set, one or more secondary cell configurations for each primary cell in the configured cell set, and a measurement configuration for each cell in the configured cell set.

15. The method of claim 8 , further comprising:

recording an identifier associated with a physical downlink shared channel (PDSCH) containing the signaling to release the selected cell;

receiving an acknowledgment of the PDSCH; and

confirming content associated with the acknowledgment indicates successful receipt of the signaling to release the selected cell.

16. An apparatus for wireless communication, comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor configured:

to receive an indication of a mobility configured cell set comprising a plurality of cells;

to receive signaling to release a selected cell of the plurality of cells from the mobility configured cell set; and

to release the selected cell from the mobility configured cell set in response to receiving the signaling wherein the signaling comprises a media access control-control element (MAC-CE) having a first octet indicating release of the selected cell from the mobility configured cell set, and a second octet indicating removal of a mobility configuration for the selected cell.

17. The apparatus of claim 16 , in which the at least one processor releases the selected cell by removing the selected cell from a carrier aggregation configuration.

18. The apparatus of claim 16 , in which the at least one processor releases the selected cell by removing a mobility configuration for the selected cell.

19. The apparatus of claim 18 , in which the signaling comprises layer one (L1) signaling.

20. The apparatus of claim 16 , in which the signaling comprises layer two (L2) signaling.

21. The apparatus of claim 16 , in which the indication is a radio resource control (RRC) configuration.

22. The apparatus of claim 16 , in which the mobility configured cell set has a configuration identifying one or more primary cell configurations for each secondary cell in the configured cell set, one or more secondary cell configurations for each primary cell in the configured cell set, and a measurement configuration for each cell in the configured cell set.

23. An apparatus for wireless communication, comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor configured:

to transmit an indication of a mobility configured cell set comprising a plurality of cells;

to transmit signaling to release a selected cell of the plurality of cells from the mobility configured cell set; and

to release the selected cell from the mobility configured cell set in response to transmitting the signaling wherein the signaling comprises a media access control-control element (MAC-CE) having a first octet indicating release of the selected cell from the mobility configured cell set, and a second octet indicating removal of a mobility configuration for the selected cell.

24. The apparatus of claim 23 , in which the at least one processor releases the selected cell by removing the selected cell from a carrier aggregation configuration.

25. The apparatus of claim 23 , in which the at least one processor releases the selected cell by removing a mobility configuration for the selected cell.

26. The apparatus of claim 23 , in which the signaling comprises layer one (L1) signaling.

27. The apparatus of claim 23 , in which the signaling comprises layer two (L2) signaling.
