Communicating Control Data in a Wireless Communication Network

Abstract:

The present invention relates to methods for sending or receiving control data in one or multiple uplink control channel resources of a wireless communication network and to corresponding devices. According to one embodiment of the invention a method of sending control data in one or multiple uplink control channel resources of a wireless communication network is provided. A wireless device receives, from a network node, information on a set of downlink component carriers configured for the wireless device. The wireless device receives, from a network node, an indication of the one or multiple uplink control channel resources. The wireless device maps first control data comprising control data for the set of configured downlink component carriers to a part of the one or multiple uplink control channel resources. And the wireless device maps second control data to a remaining part of the one or multiple uplink control channel resources.
