Abstract

The invention provides a hybrid duplex relay assisted D2D communication method. The method comprises the following five steps: a system model is established; and the transmission sub-frame is cut. Inthe time slot 1, the D2D auxiliary relay receives a cellular user signal sent by the base station and sends the D2D user signal to a D2D receiving user at the same time, and full duplex communicationmode transmission is achieved; in the time slot 2, the D2D relay stops receiving the signal from the base station, and only the transmitting antenna decodes and forwards the cellular user signal received in the time slot 1 to realize half-duplex communication mode transmission; and power control is performed on the base station and the D2D relay respectively in the time slot 1 and the time slot 2to ensure that the base station and the D2D relay perform signal transmission at the optimal transmitting power. The method has wide application value in the field of mobile cellular communication technology resource management.

Description

technical field

[0001] The invention relates to the field of resource management of mobile cellular communication technology, in particular to a hybrid duplex relay-assisted D2D communication mode and a power control method. Background technique

[0002] With the rapid development of Internet services, the amount of mobile data has shown explosive growth. In order to meet people's demand for faster transmission rates and more throughput in mobile communication systems in the next 10 to 15 years, D2D (device -to-device, data pass-through) technology. D2D communication is a technology that realizes direct communication between mobile devices that are relatively close by multiplexing channel resources of cellular users under the control of a base station. Different from traditional mobile cellular communication, the data transmission of D2D users is no longer forwarded by the base station. Compared with the transmission distance from the user to the base station, the transmis...
