OPTIMISED SERVING DUAL CELL CHANGE

摘要

FIELD: physics, communications. ^ SUBSTANCE: method and apparatus for implementing serving cell change in a multi-cell wireless transmit receive unit (WTRU) (110) are disclosed. Serving cell information is received and stored by the WTRU (110) to preconfigure a primary and a secondary serving cell of an added cell to an active set. At least one of the preconfigured primary and secondary serving cells are monitored for a handover indication. Serving cell change to the primary and secondary serving cells is performed using the preconfigured serving cell information upon receipt of a handover indication. ^ EFFECT: providing softer handover. ^ 12 cl, 4 dwg
