METHOD AND APPARATUS FOR DOWNLINK SIGNAL TRANSMISSION

摘要

The embodiment of the present invention provides a method and apparatus for downlink signal transmission. The downlink signal transmission method in the present invention comprises that: A downlink scheduling signaling or a semi- static signaling which is used for scheduling a first sub-frame set or a second sub-frame set is sent to a small station or first user equipment at a first moment in a downlink carrier frequency band; The signaling for scheduling the first sub-frame set includes first instruction information for instructing the small station or the first user equipment to receive a downlink signal at a second moment in an uplink carrier frequency band; The first instruction information is represented by the bits which are occupied by a carrier identifier CIF field; The downlink signal is sent to the small station or the first user equipment at the second moment in the uplink carrier frequency band. By the embodiment of the present invention, the utilization rate of uplink resource can be increased and the effective transmission of the data in a control channel and a data channel can be ensured.
