Error handling in dual active link handover

An apparatus for wireless communications at a first network device, comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors, wherein the one or more memories comprise instructions executable by the one or more processors to cause the apparatus to:
• transmit a configuration message or a dual active link handover command to a user equipment (UE) indicating a configuration associated with the UE performing a dual active link handover, wherein the configuration indicates a temporal relationship between a first transmission opportunity and a second transmission opportunity subsequent to the first transmission opportunity, the temporal relationship comprising a re-transmission timer;
• identify that the UE is performing the dual active link handover, wherein the UE concurrently maintains a first communication link with the first network device and a second communication link with a second network device while performing the dual active link handover;
• transmit a message to the UE in the first transmission opportunity, wherein the first network device activates the re-transmission timer after transmitting the message;
• and
• transmit, based at least in part on an expiration of the re-transmission timer, the message to the UE in the second transmission opportunity subsequent to the first transmission opportunity based at least in part on the UE performing the dual active link handover and based at least in part on the temporal relationship between the first transmission opportunity and the second transmission opportunity indicated by the configuration.

An apparatus for wireless communications at a first network device, comprising:

• means for transmitting a configuration message or a dual active link handover command to a user equipment (UE) indicating a configuration associated with the UE performing a dual active link handover, wherein the configuration indicates a temporal relationship between a first transmission opportunity and a second transmission opportunity subsequent to the first transmission opportunity, the temporal relationship comprising a re-transmission timer;
• means for identifying that the UE is performing the dual active link handover, wherein the UE concurrently maintains a first communication link with the first network device and a second communication link with a second network device while performing the dual active link handover;
• means for transmitting a message to the UE in the first transmission opportunity, wherein the first network device activates the re-transmission timer after transmitting the message;
• and
• means for transmitting, based at least in part on an expiration of the re-transmission timer, the message to the UE in the second transmission opportunity subsequent to the first transmission opportunity based at least in part on the UE performing the dual active link handover and based at least in part on the temporal relationship between the first transmission opportunity and the second transmission opportunity indicated by the configuration.

A non-transitory computer-readable medium storing code for wireless communications at a first network device, the code comprising instructions executable by one or more processors to:

• transmit a configuration message or a dual active link handover command to a user equipment (UE) indicating a configuration associated with the UE performing a dual active link handover, wherein the configuration indicates a temporal relationship between a first transmission opportunity and a second transmission opportunity subsequent to the first transmission opportunity, the temporal relationship comprising a re-transmission timer;
• identify that the UE is performing the dual active link handover, wherein the UE concurrently maintains a first communication link with the first network device and a second communication link with a second network device while performing the dual active link handover;
• transmit a message to the UE in the first transmission opportunity, wherein the first network device activates the re-transmission timer after transmitting the message;
• and
• transmit, based at least in part on an expiration of the re-transmission timer, the message to the UE in the second transmission opportunity subsequent to the first transmission opportunity based at least in part on the UE performing the dual active link handover and based at least in part on the temporal relationship between the first transmission opportunity and the second transmission opportunity indicated by the configuration.
