Abstract
Method, system and devices for managing carrier aggregation in a radiocommunication system. According to the method, the user equipment (3) carries out the steps of: receiving (7;12) a list of multiple carriers in a determined order; and selecting (9;14) one carrier from the list of multiple carriers as a serving carrier, based on a position of said carrier in the list of multiple carriers.
Claims7
A method of managing carrier aggregation in a radio communication system by a user equipment, the method comprising:
- receiving a list of multiple carriers in a determined order,
- wherein the list of multiple carriers lists multiple downlink carriers;
- determining whether or not a serving carrier is explicitly indicated either within the received list of multiple carriers or before receiving the list of multiple carriers;
- selecting a carrier from the list of multiple carriers as the serving carrier if it is determined that the serving carrier is not explicitly indicated, the selection of the carrier based on a position of the carrier in the list of multiple carriers,
- wherein the position of the serving carrier is a first position in the list of multiple carriers;
- and
- receiving control information on the selected carrier before receiving on the other carriers in the list of multiple carriers, the received control information including system information or paging information.
A user equipment configured for managing carrier aggregation in cooperation with a radio communication system, the user equipment comprising:
- a receiver configured to receive a list of multiple carriers in a determined order,
- wherein the list of multiple carriers lists multiple downlink carriers;
- and
- a processor configured to:
- determine whether or not a serving carrier is explicitly indicated either within the received list of multiple carriers or before the list of multiple carriers is received;
- select a carrier from the list of multiple carriers as the serving carrier if it is determined that the serving carrier is not explicitly indicated, the selection of the carrier based on a position of the carrier in the list of multiple carriers,
- wherein the position of the serving carrier is a first position in the list of multiple carriers;
- and
- receive control information on the selected carrier before receiving on the other carriers in the list of multiple carriers, the received control information including system information or paging information.
A method of managing carrier aggregation in a radio communication system by a user equipment, the method comprising:
- receiving a list of multiple carriers in a determined order,
- wherein the list of multiple carriers lists multiple uplink carriers;
- determining whether or not a serving carrier is explicitly indicated either within the received list of multiple carriers or before receiving the list of multiple carriers;
- selecting a carrier from the list of multiple carriers as the serving carrier if it is determined that the serving carrier is not explicitly indicated, the selection of the carrier based on a position of the carrier in the list of multiple carriers,
- wherein the position of the serving carrier is a first position in the list of multiple carriers;
- and
- transmitting control information on the selected carrier before transmitting on the other carriers in the list of multiple carriers, the transmitted control information including a handover complete message.
