摘要： The present invention relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI (Channel State Information) trigger signaling, so that a base station transmits a CSI-RS (Channel State Information-Reference Signal) only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced, thereby improving the spectrum efficiency of the system.

摘要： The present invention relates to a signal transmission method and an apparatus. The signal transmission method includes: performing, by a base station, rate matching of a unicast signal according to a multicast/broadcast single frequency network MBSFN reference signal MBSFN RS; and sending, by the base station, the unicast signal to user equipment UE. By means of the signal transmission method and the apparatus, resource usage can be increased, and continuity and effectiveness of performing broadcast multicast related measurement by UE are ensured.

摘要： Embodiments of the present invention disclose a method for detecting a signal on an unlicensed spectrum channel, user equipment, and a base station. The method includes: receiving, by user equipment, instruction information sent by a base station; and starting, by the user equipment according to the instruction information, to detect a signal on an unlicensed spectrum channel. According to the present invention, only when receiving the instruction information sent by the base station, the user equipment detects the signal on the unlicensed spectrum channel according to the instruction information. This reduces power consumption of the user equipment.

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.
