Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to switch from a first cell of a first distributed unit (DU) to a second cell of a second DU, wherein the first DU and the second DU are included in a set of DUs of a central unit (CU). The UE may communicate, using layer 1 (L1) or layer 2 (L2) signaling to change an activation status of at least one cell of the first DU or the second DU. The UE may switch from the first cell to the second cell in connection with the change to the activation status of the at least one cell of the first DU or the second DU. Numerous other aspects are provided.

A method of wireless communication performed by a user equipment (UE), comprising:
- determining to switch from a first cell of a first distributed unit (DU) to a second cell of a second DU, wherein the first DU and the second DU are included in a set of DUs of a central unit (CU);
- communicating, using layer 1 (L1) or layer 2 (L2) signaling, with at least one of the first DU or the second DU to change an activation status of at least one cell of the first DU or the second DU based at least in part on determining to switch from the first cell to the second cell;
- and
- switching from the first cell to the second cell in connection with the change to the activation status of the at least one cell of the first DU or the second DU.
A method of wireless communication performed by a wireless communication device, comprising:
- communicating, using layer 1 (L1) or layer 2 (L2) signaling, with at least one of a central unit (CU), a distributed unit (DU), or a user equipment (UE) to change an activation status of at least one cell;
- and
- switching the UE from a first cell to a second cell in connection with the change to the activation status of the at least one cell.
A user equipment (UE) 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 to switch from a first cell of a first distributed unit (DU) to a second cell of a second DU, wherein the first DU and the second DU are included in a set of DUs of a central unit (CU);
- communicate, using layer 1 (L1) or layer 2 (L2) signaling, with at least one of the first DU or the second DU to change an activation status of at least one cell of the first DU or the second DU based at least in part on determining to switch from the first cell to the second cell;
- and
- switch from the first cell to the second cell in connection with the change to the activation status of the at least one cell of the first DU or the second DU.
A wireless communication device 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:
- communicate, using layer 1 (L1) or layer 2 (L2) signaling, with at least one of a central unit (CU), a distributed unit (DU), or a user equipment (UE) to change an activation status of at least one cell;
- and
- switch the UE from a first cell to a second cell in connection with the change to the activation status of the at least one cell.
