1. A method for sending an uplink resource indication to a user terminal, comprising: composing, by a base station, an uplink resource grant indication (ul grant) which carries an uplink resource index, wherein a corresponding relationship exists between the uplink resource index and one or more uplink subframes, the corresponding relationship is determined by an uplink-downlink subframe ratio and the number of uplink subframes is more than the number of downlink subframes in the uplink-downlink subframe ratio; and sending, by the base station, the ul grant to the user terminal; wherein the corresponding relationship between the uplink resource index and the one or more uplink subframes is established by the following: combining, by the base station, the one or more uplink subframes into a group, and correlating, by the base station, the group with the uplink resource index, so as to establish the corresponding relationship between the uplink resource index and the one or more uplink subframes; wherein each uplink resource index is correlated with a group of one or more uplink subframes, and the uplink subframes in each group are not completely the same.
