Time-division multiplexing of uplink communications during make-before-break handover

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• receive a message including a handover command instructing the UE to execute a make-before-break handover procedure and a time-division multiplexing pattern configuration for using time-division multiplexing during the make-before-break handover procedure;
• determine a prioritization rule that indicates a relative priority for different uplink communications included in a group of uplink communications, wherein the prioritization rule is different than the time-division multiplexing pattern configuration, and wherein the group of uplink communications includes at least a first uplink communication and a second uplink communication to be transmitted by the UE using time-division multiplexing during the make-before-break handover procedure;
• and
• transmit, based at least in part on the time-division multiplexing pattern configuration and the prioritization rule, the first uplink communication to a target network entity and the second uplink communication to a source network entity using time-division multiplexing during the make-before-break handover procedure.

A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
• determine a prioritization rule that indicates a relative priority for different uplink communications included in a group of uplink communications, wherein the group of uplink communications includes at least a first uplink communication and a second uplink communication to be transmitted by the UE using time-division multiplexing during a make-before-break handover procedure;
• and
• transmit, based at least in part on the prioritization rule, the first uplink communication to a target network entity and the second uplink communication to a source network entity using time-division multiplexing during the make-before-break handover procedure,
• wherein the time-division multiplexing is active after completion of a random access procedure with the target network entity, and the UE is configured to transmit at least one of a sounding reference signal, a physical uplink control channel communication, or a physical uplink shared channel communication to both the target network entity and the source network entity while the time-division multiplexing is active.
