Problems solved by technology

[0004] In the existing D2D transmission scheme, the power equipment uses the maximum power to send the signal. Although this will have a lower transmission delay, due to the characteristics of the same frequency transmission technology, when there are many devices within the range of the base station, it will Cellular users have a greater impact, and at the same time consume a lot of energy
Moreover, when the distance between the cellular user and the two power devices is large, the same-frequency interference generated by full-duplex D2D transmission and uplink simultaneous transmission on the same frequency will seriously affect the delay symmetry of the power device, thereby affecting the intelligence Grid operation efficiency and stability

Description

technical field [0001] The present invention belongs to the technical field of wireless communication, and in particular relates to a power equipment transmission power optimization method oriented to full-duplex D2D communication delay symmetry, and also relates to a power equipment transmission power optimization device oriented to full-duplex D2D communication time delay symmetry. Background technique [0002] With the rapid development of wireless mobile communications, people's demand for broadband resources is increasing. However, as a non-renewable and scarce resource, radio spectrum has a very limited supply and a low utilization rate of spectrum resources. In this context, equipment Device-to-device (D2D) communication technology emerges as the times require. [0003] Device-to-device (D2D) technology allows adjacent devices to communicate directly without relying on the participation of base stations. It has the characteristics of fast speed, low delay, and wide co...
