Abstract: The present disclosure relates to a method and an apparatus of transmitting a hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK). A first set of HARQ-ACK/NACK including at least one timing value is identified. The at least one HARQ-ACK/NACK timing value is a time difference between a downlink time unit in which a physical downlink shared channel (PDSCH) is received and an uplink time unit in which a HARQ-ACK/NACK associated with the PDSCH is transmitted. A second set including at least one downlink time associated with a HARQ-ACK/NACK feedback is determined based on the first set. A codebook for the HARQ-ACK/NACK is generated based on a size of the codebook. The size of the codebook is identified based on the second set including the at least one downlink time. The codebook for the HARQ-ACK/NACK is transmitted to the base station in the uplink time unit.

Abstract: Examples of the present invention provide a method for allocating Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) channel resources supporting transmit diversity and channel selection. The method includes: receiving, by a UE, Physical Downlink Control Channel (PDCCH) information and Physical Downlink Shared Channel (PDSCH) data from a base station through two Carrier Components (CCs); obtaining, by the UE according to specific indication information, Physical Uplink Control Channel (PUCCH) channel resources required for transmitting HARQ-ACK feedback information using a transmit diversity technique; and transmitting, by the UE, the HARQ-ACK feedback information on the obtained PUCCH channel resources adopting the transmit diversity technique. According to the method provided by the examples of the present invention, it is possible to allocate HARQ-ACK channel resources to the UE reasonably and avoid waste of channel resources in the premise that channel selection and SORTD technique are supported.
