Downlink data transfer flow control during carrier aggregation
First Claim
1. A method for controlling a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation, the method comprising:
- detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection; and
in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.

Abstract
Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.
