When the embodiment of the present invention is to relaying user device transmissions data the transmission mode that uses with no restrictions, for example, relaying User equipment can be carried out data transmission using the mode of decoding forwarding (Decode and Forward, DF), can also be used The mode of amplification forwarding (Amplified and Forward, AF) carries out data transmission.
When candidate relay user equipment is carried out data transmission by the way of DF, above-mentioned cost function (1) can be specific Are as follows:
That is, willIt can be set to takeWithIn smaller value.
Above-mentioned cost function (2) is deformed, available:
First item is two subprocess for transmitting data in denominator it can be seen from the expression formula of above-mentioned cost function (3) Social networks intensity average value square, be denoted as social networks mean intensity.Section 2 is two two subprocess The variance yields of the intensity of social networks is denoted as social networks imbalance intensity.Two subprocess are that data are passed by source user equipment It transports to trunk subscriber equipment and data and target UE is transmitted to by trunk subscriber equipment.
From cost function expression formula (3) as can be seen that in the case where communication channel state information is certain, trunk subscriber Social networks mean intensity between equipment and source user equipment and target UE is bigger, payment needed for target UE Cost it is smaller.Reflection is in real life, it can be understood as when needing to ask trunk subscriber equipment to assist to carry out data transmission When, the social networks between trunk subscriber equipment and source user equipment are closer and trunk subscriber equipment is set with target user Social networks between standby are closer, and the cost paid is smaller.
Similarly, the social networks imbalance intensity between trunk subscriber equipment and source user equipment and target UE is got over Small, the cost paid needed for target UE is smaller.Reflection is in real life, it can be understood as when needing to ask trunk subscriber When equipment assistance carries out data transmission, the social networks and trunk subscriber equipment and target of trunk subscriber equipment and source user equipment Social networks difference between user equipment is smaller, and close and distant difference is lower, and the cost for needing to pay is smaller.
Cost function in the embodiment of the present invention is simultaneously by the channel status between source user equipment and trunk subscriber equipment Channel state information and social networks between information and social networks and trunk subscriber equipment and target UE consider Inside, trunk subscriber can be selected to avoid the channel state information relied only between source user equipment and trunk subscriber equipment in this way Equipment is influenced caused by efficiency of transmission, and then can be improved the efficiency of transmitted data on network.
