FIELD: electrical communication engineering.
SUBSTANCE: invention relates to wireless communication. Method comprises the stages of: configuring P-cell FDD and S-cell TDD; configuring the first SF UL-DL pattern for S-cell TDD in accordance with the pattern specification information received through signal L1; and transmitting HARQ-ACK information relating to SF in which the S-cell TDD transmission direction is UL through PUCCH SR based on the first UL-DL SF pattern, while HARQ-ACK information includes HARQ-ACK responses for both the P-cell and the S-cell when the direction of transmission of the S-cell TDD to SF is DL, based on the SF UL-DL reference pattern configured for the S-cell TDD, with respect to the HARQ-ACK feedback, and HARQ-ACK information includes the HARQ-ACLK response only for the P-cell when the transmission direction of the S-cell TDD to SF is UL, based on the SF UL-DL pattern.
EFFECT: technical result consists in ensuring the effective performance of signal transmission and reception processes.
