Abstract
The aim of the present invention is to provide an efficient and reliable transmission/reception mechanisms for a communication system with multiple component carriers, each of which further includes physical resources such as transmission slot/symbol, subcarrier/frequency subband, code, or radiation pattern. Accordingly, the control signal of a component carrier comprises a scheduling assignment specifying for said component carrier a resource for transmission of a data signal, and an allocation map specifying that a scheduling assignment has been sent for another component carrier. Signalizing the allocation map enables detection of possibly missed scheduling assignments.

16. A method for transmitting a data signal and a control signal in a wireless communication system with multiple component carriers, each component carrier comprising resources specified by at least one of transmission slot, subband frequency, code and radiation pattern, the method comprising the step of:
-
generating a scheduling assignment specifying for a first component carrier a resource for transmission of a data signal; determining an allocation map specifying whether for a second component carrier a scheduling assignment has been generated; transmitting a control signal within the first component carrier, the control signal comprising the generated scheduling assignment and the allocation map. - View Dependent Claims (17, 18, 19, 20)

21. A method for receiving a data signal and a control signal in a wireless communication system with multiple component carriers, each component carrier comprising resources specified by at least one of transmission slot, subband frequency, code and radiation pattern, the method comprising the steps of
receiving a control signal within a first component carrier and within a second component carrier; -
extracting from the control signal within the first component carrier a scheduling assignment specifying for the first component carrier a resource for receiving a data signal; extracting from the control signal within the first component carrier an allocation map specifying whether for the second component carrier a scheduling assignment has been generated; and evaluating based on the allocation map and on a control signal within the second component carrier whether a scheduling assignment for the second component carrier has been sent and received. - View Dependent Claims (22, 23, 24, 25)
