摘要： The embodiments of the present invention provide a method and device for sending data. A second network equipment receives user data sent by a first network equipment through a first interface. The second network equipment receives control signaling sent by the first network equipment through a second interface, wherein the second interface is an air interface. The second network equipment sends the user data to a user equipment according to the control signaling. In the embodiments of the present invention, the first network equipment can send the control signaling to the UE and the second network equipment through the air interface, and does not send the control signaling and data signaling to the second network equipment through the same X2 interface, so that the first interface with longer transmission delay is prevented from being used for sending the control signaling, and the transmission delay of the control signaling between the network equipments is shortened.

摘要： The present invention provides a method and a device for transmitting and receiving control signaling. The method includes: determining an original size of a DCI format which is in a first group and is the format of DCI to be transmitted; determining, according to a current transmission configuration, a second group of DCI formats that can be used under the current transmission configuration; comparing a size of the DCI format in the second group with the original size of the DCI format in the first group, and if the second group includes a DCI format that has a same size as a DCI format in the first group, appending a bit to the DCI format which is in the first group of DCI formats and has the same size as the DCI format in the second group, so that size of the DCI format in the first group after the bit appending is different from that of the DCI format in the second group; and transmitting, according to the DCI format with the appended bit in the first group, the DCI to be transmitted. According to embodiments of the present invention, DCI formats under a current configuration may be easily distinguished with a relative small overhead.
