Abstract:
1. A method of wireless communication at a user equipment (UE), comprising: communicating over an anchor carrier and at least one initial secondary carrier; receiving an order to change the at least one initial secondary carrier; and deactivating the at least one initial secondary carrier and activating at least one subsequent secondary carrier, in response to the order, wherein pre-configuration information of the at least one subsequent secondary carrier is received at the UE from a radio network controller (RNC) via a radio resource control (RRC) reconfiguration message prior to the receiving of the order, and wherein an active set is maintained for the subsequent secondary carrier at the UE prior to the receiving of the order, and wherein the at least one initial secondary carrier and the at least one subsequent secondary carrier are adjacent to each other, and wherein the order to change is received from a base station in the form of a High Speed-Shared Control Channel (HS-SCCH) order and is at least based on load imbalance on secondary carriers determined by the base station.
