Abstract: A communication is executed between a user equipment and a communication network based on carrier aggregation using a first group of at least two PUCCH groups, the first group including a primary serving cell that carries a first PUCCH, and first serving cells which use the first PUCCH, and a second group of the at least two PUCCH groups, the second group including a secondary serving cell that carries a second PUCCH, and second serving cells which use the second PUCCH. In case a predetermined condition occurs, the communication is continued by exchanging the first group by the second group wherein the secondary serving cell that carries the second PUCCH becomes the primary serving cell and vice versa.
