Summary:Embodiments of the present invention provide a method for transmitting a PUSCH in an LAA-LTE system and user equipment. The method includes: determining, by the UE, an alternate carrier when a first unlicensed carrier is unavailable in a subframe n+k, and sending, by the UE, the PUSCH to a base station by using the alternate carrier; or when a first unlicensed carrier is unavailable in a subframe n+k, sending, by the UE, the PUSCH to a base station in any one of a subframe n+k+1 to a subframe n+k+m by using the first unlicensed carrier. The PUSCH is sent by using the alternate carrier or with a delay of 1 to m subframes, so that a delay in sending uplink data by the UE is reduced.
