FIELD: wireless communication.
SUBSTANCE: wireless apparatus transmits a hybrid automatic re-transmission request (HARQ) feedback signal to the base station via a physical uplink control channel (PUCCH). The method comprises a stage of determining that a first PUCCH resource has been assigned to the wireless apparatus for transmitting the HARQ feedback signal. The first PUCCH resource is assigned from multiple PUCCH resources grouped into sets. The method comprises a stage of replacing the first PUCCH resource with a second PUCCH resource. The second PUCCH resource belongs to the same set as the first PUCCH resource. The HARQ feedback signal is transmitted to the base station via the second PUCCH resource.
EFFECT: increased productivity with maintained possibility to schedule optional transmissions.
