Abstract
Official abstract text for this publication.
A method and device for carrier management in a carrier aggregation system, includes signaling which carries an additional carrier measurement indication sent to a User Equipment (UE); a measurement report received from the UE; when the downlink traffic of the UE increases, if the recorded carriers in the current downlink carrier set of the UE can not meet the requirement of the downlink traffic data rate, according to the additional carrier measurement report, at least one additional carrier is configured and activated, and the UE is notified to perform the corresponding configuration operation. In addition, according to the measurement result and the change in the downlink traffic of the UE, the base station can also perform the deactivation, activation replacement and removal of the additional carrier for the user, and notify the UE to perform the corresponding configuration operations.
First claim
Opening claim text (preview).
What is claimed is: 1. A method performed by a base station for a carrier configuration and activation in a carrier aggregation system, comprising: transmitting a first signaling to configure at least one additional carrier to a user equipment (UE) at which the additional carriers are deactivated, and to configure a timer to each additional carrier for the UE by which the carrier is deactivated after the timer expiry; transmitting a second signaling that carries an activation in…
