Load balancing using dynamic dual active protocol stacks

A wireless transmit/receive unit (WTRU) comprising:

• a processor configured to:
• perform a single communication operation with a first network entity;
• receive configuration information, wherein the configuration information comprises information associated with a performance of a dual communication operation, and wherein the configuration information indicates a bearer associated with the dual communication operation and a data threshold associated with the bearer;
• perform a first dual communication operation based on a first amount of data associated with the bearer being above the data threshold, wherein the first dual communication operation comprises communicating with the first network entity and a second network entity;
• release the first dual communication operation based on a second amount of data associated with the bearer being below the data threshold, wherein releasing the first dual communication operation comprises communicating with a single network entity, and wherein the single network entity is the first network entity;
• send an indication, wherein the indication indicates that the dual communication operation is released;
• and
• based on a third amount of data associated with the bearer being above the data threshold, perform a second dual communication operation, wherein the second dual communication operation comprises communicating with the first network entity and a third network entity.
