Abstract: Disclosed are an inter-terminal device-to-device communication method and system, which relate to the technical field of wireless communications. The method includes that a source terminal initiates a communication request for device-to-device (D2D) communication with a destination terminal; according to the D2D communication request, whether the source terminal and the destination terminal can conduct the device-to-device communication is detected; if the detection result is that the source terminal and the destination terminal can conduct the device-to-device communication, a D2D communication link is established between the source terminal and the destination terminal; the source terminal and the destination terminal use the D2D communication link to conduct the device-to-device communication.

Abstract: A data transmission/receiving method and device are provided. The transmission method is applied to a base station, and includes allocating a network resource required for D2D communications for each UE in a UE group and using the network resource as a component carrier of each UE, each UE supporting carrier aggregation, and dividing the data to be transmitted to the UE group into a plurality of pieces of component data information and respectively transmitting same to each UE, each UE sharing the plurality of pieces of component data information transmitted to each UE via the component carrier. The method and device provide a solution which uses D2D technology in a carrier aggregation yet, thereby achieving the convergence of carrier aggregation and D2D technology and improving the transmission efficiency of a mobile communication network while reducing the burden of the mobile communication network.

Abstract: A power control method and a base station thereof are provided, in which the method includes that a base station determines a minimum power enhancement value of a cellular user according to the signal quality which is respectively reported from a D2D user and the cellular user, in which the minimum power enhancement value is obtained according to the principle that the communication signal quality of the cellular user and the communication signal quality of the D2D user are both higher than preset signal quality; the base station controls the power of the cellular users according to the minimum enhancement value when the base station determines that the minimum power enhancement value is smaller than the PH value. The implementation of the disclosure solves the problem that D2D will interfere with a base station and then affect the normal communication of cellular users when the D2D shares the cellular mobile upstream resources in a cellular mobile network with a D2D communication.

Abstract: The disclosure discloses a radio resource control method and device, the radio resource control method includes that: a User Equipment (UE) detects the Reference Signal Receiving Power (RSRP) of each component carrier and determines whether or not a preset requirement for image interference due to power imbalance is met according to the result of the detection; and a preset image interference avoidance strategy is performed if the preset requirement for image interference due to power imbalance is met. The disclosure is capable of addressing the problem that the power imbalance between component carriers adjacent in frequency degrades communication performance.

Abstract: The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded.
