Methods and apparatus are provided for a User Equipment to transmit acknowledgement information together with data information to a base station during a Transmission Time Interval. A number of nominal resources for the transmission of the first set of AIBs is compared to a number of resources available to the UE for transmission of the acknowledgement information. The first set of AIBs is transmitted if the number of nominal resources is less than or equal to the number of available resources. A second set of AIBs is selected from the first set of AIBs and bundling operations are performed over respective distinct subsets of AIBs in the second set of AIBs to obtain a third set of AIBs if the number of nominal resources is greater than the number of available resources. The third set of AIBs and a fourth set of AIBs are transmitted.
