COMPONENT CARRIER ACTIVATION AND DEACTIVATION USING RESOURCE ASSIGNMENTS
First Claim
1. A communication method comprising:
- receiving resource assignment information including a plurality of bits that indicate activation/deactivation statuses of respective downlink component carriers, the downlink component carriers being secondary downlink component carriers added to a primary component carrier which is always activated, each downlink component carrier corresponding to one bit included in the plurality of bits, and the one bit indicating that a corresponding downlink component carrier is to be activated or deactivated; and
activating or deactivating each of the downlink component carriers according to the resource assignment information.

Abstract
This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e. indicate which downlink component carrier(s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.
