Abstract
Official abstract text for this publication.
An apparatus and method enables a dynamic change from one carrier to another in a wireless telecommunication system. In one example, user equipment receives a preconfiguration message adapted to enable the user equipment to be preconfigured for an initial carrier and a subsequent carrier. Here, the user equipment initially communicates over an air interface utilizing the initial carrier frequency. Upon the satisfaction of certain conditions, such as one of the initial carriers being heavily loaded or nearing its capacity, a Node B provides an order to the user equipment to switch from its initial carrier to the secondary carrier, which was preconfigured. In this way, relatively rapid carrier switching provides for enhanced load balancing largely controlled by the Node B.
First claim
Opening claim text (preview).
What is claimed is: 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…
