FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a wireless systems. The method and apparatus for user equipment (UE) include transmitting HARQ-ACK information over a physical uplink shared channel (PUSCH) in response to reception of at least one transport block (TB), when the UE is configured by a base station with multiple downlink (DL) component carriers (CC), for selecting a single PUSCH for transmitting uplink control information (UCI), when the UE has multiple PUSCH transmissions, and for applying transmission diversity to the HARQ-ACK transmission in a PUSCH.
EFFECT: improved reliability of HARQ-ACK reception when it is encoded using a block code relative to when it is encoded using a repetition code.
