FEEDBACK METHOD OF CONTROL INFORMATION, USER EQUIPMENT AND BASE STATION

摘要

The present invention provides a feedback method of control information, a user equipment (UE) and a base station. The feedback method of the control information comprises: a UE receiving a ULGrant on subframe n-k', wherein the ULGrant is used for instructing to send a PUSCH on subframe n, and k' is an uplink association index; based on a downlink reference ratio, determining HARQ-ACK information, wherein the HARQ-ACK information is borne on the PUSCH; and sending the PUSCH on the subframe n. The present invention uses a manner where the HARQ-ACK information is determined based on the downlink reference ratio, and the HARQ-ACK information does not need to be determined based on a value instructed by a DAI carried by the ULGrant, avoiding a technical problem that incorrect HARQ-ACK information is fed back.
