Abstract:
1. A method for transmitting a data signal and a control signal in a wireless communication system supporting aggregation of a plurality of component carriers, each component carrier comprising resources specified by at least transmission slot and subband frequency, 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 represented by a bitmap with each bit specifying whether, for a single respective carrier of the plurality of component carriers, and for which of the plurality of component carriers including 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 for the first component carrier and the allocation map; transmitting the data signal using the resource for transmission of the data signal, said resource for transmission of the data signal being specified by the scheduling assignment for the first component carrier; and receiving, within a resource for transmission of an acknowledgement signal linked with the resource for transmission of the data signal specified for the first component carrier, an acknowledgement signal related to the transmitted data signal, wherein the acknowledgement signal is common for data signals in a plurality of component carriers, wherein a control signal within the second component carrier comprises a relative index linked to the resource for transmission of the acknowledgement signal within the first component carrier.
