FIELD: wireless communications.
SUBSTANCE: invention relates to radio communication. Said technical result is achieved by that at first, value of index for control channel element (CCE) is achived, planned for user device in improved physical downlink control channel (E-PDCCH); then, based on index and first parameter, determining PUCCH resource used for transmitting HARQ feedback signal of user device in relation to its corresponding PDSCH, wherein first parameter is reference value, which must be used when determining PUCCH resource used for transmitting HARQ feedback signal of user device in relation to its corresponding PDSCH, in case of CCE scheduling for user device in E-PDCCH.
EFFECT: technical result is determination of service life of physical uplink control channel (PUCCH) for user device in relation to its corresponding physical downlink shared channel (PDSCH).
