Method and base station for transmitting scheduling information

摘要

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.

1. A method for transmitting scheduling information for scheduling of an uplink subframe, the method comprising:
determining whether or not a Multicast Broadcast Single Frequency Network (MBSFN) subframe is used for transmitting the scheduling information for scheduling of the uplink subframe, the scheduling of the uplink subframe being based on a first scheduling timing, the first scheduling timing being determined based on a first Time Division Duplex (TDD) uplink and downlink configuration scheme; obtaining a first equivalent TDD uplink and downlink configuration scheme from the first TDD uplink and downlink configuration scheme in a case that the MBSFN subframe is not used for transmitting the scheduling information for scheduling of the uplink subframe, the first equivalent TDD uplink and downlink configuration scheme being obtained by assuming the MBSFN subframe as the uplink subframe; selecting a downlink subframe used for transmitting the scheduling information for scheduling of the uplink subframe, the downlink subframe being selected based on the first equivalent TDD uplink and downlink configuration scheme and a second TDD uplink and downlink configuration scheme; and transmitting in the selected downlink subframe, the scheduling information for scheduling of the uplink subframe, the scheduling of the uplink subframe being based on a second scheduling timing, the second scheduling timing being determined based on the first equivalent TDD uplink and downlink configuration scheme and the second TDD uplink and downlink configuration scheme, wherein the first scheduling timing and the second scheduling timing are different.
