Methods and device for transmitting and receiving ACK/NACK (acknowledgement/negative acknowledgement)

Abstract

The invention discloses methods and device for transmitting and receiving ACK/NACK (acknowledgement/negative acknowledgement). The method for transmitting the ACK/NACK comprises: when a PUSCH (physical uplink shared channel) used for transmitting uplink control information and determined by user equipment (UE) is a PUSCH which has no corresponding PDCCH (physical downlink control channel), or a PUSCH under the uplink configuration and downlink configuration 0 in a TDD (time division duplexing) system, or a PUSCH in an FDD (frequency division duplexing) system, if the UE does not receive the PDSCH in a downlink subframe which performs ACK/NACK feedback in an uplink subframe which sends the PUSCH correspondingly, or if the UE instructs the PDCCH released by downlink SPS (semi-persistent scheduling) resources, the UE determines the ACK/NACK feedback information transmitted on the PUSCH; the UE determines the resources for transmitting the ACK/NACK feedback information on the PUSCH; and the UE transmits the ACK/NACK feedback information on the determined resources for transmitting the ACK/NACK feedback information on the PUSCH. According to the invention, the inconformity of understanding on whether the ACK/NACK is transmitted on the PUSCH by a base station and the UE caused by the UE downlink data loss can be avoided, and the transmission reliability of the downlink data and ACK/NACK feedback information can be improved.
