Title:
METHODS AND APPARATUSES FOR CARRIER ACTIVATION OR DEACTIVATION IN A MULTI CARRIER RADIO SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/101510
Kind Code:
A3
Abstract:
A signaling mechanism is used for Dual carrier High Speed Uplink Packet Access, DC-HSUPA. The mechanism is used by a UE and RAN to allow the UE to perform secondary carrier activation or deactivation. The secondary carrier activation the deactivation performed by the UE in a manner will ensures that the UE and RAN have the same view of the current activation state. The UE transmits a request for carrier activation or deactivation to RAN over an activated carrier and awaits a positive or negative acknowledgement from RAN, or sends the signaling retroactively as a notification that a carrier has been deactivated.
