The present invention provides a method and a base station each for transmitting uplink scheduling information. The method includes the steps of: for an uplink subframe to be scheduled in accordance with the uplink scheduling information, selecting, from a downlink subframe candidate group, a downlink subframe usable for transmission of the uplink scheduling information, the downlink subframe candidate group including (1) a first downlink subframe corresponding to the uplink subframe in accordance with a predetermined scheduling timing and (2) one or more second downlink subframes each not corresponding to the uplink subframe in accordance with the predetermined scheduling timing; and transmitting the uplink scheduling information in the selected downlink subframe.

Method and base station for transmitting uplink scheduling information

The present disclosure provides a method and base station for transmitting scheduling information. The method comprises: determining that a downlink subframe corresponding to the uplink subframe according to a first scheduling timing corresponding to a first Time Division Duplex (TDD) uplink and downlink configuration scheme of a plurality of TDD uplink and downlink configuration schemes is unavailable for transmitting the scheduling information; obtaining a first equivalent TDD uplink and downlink configuration scheme by treating one or more downlink subframes, including the downlink subframe, in a radio frame as uplink subframes; selecting a downlink subframe corresponding to the uplink subframe according to a second scheduling timing corresponding to a second TDD uplink and downlink configuration scheme of the plurality of TDD uplink and downlink configuration schemes, wherein a set of downlink subframes specified in the second TDD uplink and downlink configuration scheme is a subset of a set of downlink subframes specified in the first equivalent TDD uplink and downlink configuration scheme; and transmitting the scheduling information in the selected downlink subframe.
