Description

Method and system for radio resource sharing and operation mode control management
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a method and a system for sharing wireless resources and controlling and managing a working mode.
Background
5G D2D (Device-to-Device) terminal direct technology means that a nearby terminal can perform data transmission by direct communication in a short distance without forwarding through a base station. Due to the advantages of short distance and direct connection, the D2D technology can improve the use efficiency of wireless resources and expand the network coverage, so a great deal of research is obtained in the construction of 5G, the D2D technology can be applied to more scenes in the future, and the user experience is improved. Massive mimo (massive mimo) is a key technology for improving system capacity and spectrum utilization rate in a 5G mobile communication system, and data performance and communication quality are improved by providing a plurality of transmitting antennas at a transmitting end and a plurality of receiving antennas at a receiving end.
The wireless resources used by the 5G D2D communication technology are commonly available in two ways: the method comprises the following steps that firstly, an orthogonal mode is adopted, and wireless resources of cellular communication are shared in the orthogonal mode, so that unused resources of the cellular communication are used, and the method is suitable for a scene that the wireless resources are used under the condition of having free wireless resources; and secondly, the multiplexing mode is a reasonable mode for multiplexing the authorized frequency band, so that the wireless spectrum is efficiently utilized, and the method is suitable for scenes with high wireless resource use. Therefore, the sharing method of the wireless resource of 5G D2D becomes a hot spot of research of 5G D2D.
There are two modes of operation for MIMO (multiple input multiple output) technology: the diversity mode is that the same path of data stream is transmitted through a plurality of antennas at a transmitting end, data information reaches a receiving end through a plurality of paths, the receiving end performs correlation combination on a plurality of paths of received signals, and reliable received signals are selected to obtain diversity gain, thereby effectively reducing signal fading influence and improving link reliability; and the second is a multiplexing mode, wherein the multiplexing mode is that a plurality of parallel channels are established by an antenna array of the MIMO, and each channel transmits different data streams, so that the improvement of the data transmission rate is realized. The frequency used by 5G is higher, the frequency is higher, the coverage area is smaller, especially for 5G millimeter wave communication, which all need to utilize antenna technology to overcome the problem of coverage limitation, wherein massive MIMO has also been widely researched and applied, and is the key to research on selection of diversity and multiplexing modes.
The research in the prior art always focuses on the optimization and selection of a wireless resource sharing mode of 5G D2D and an algorithm in an MIMO working mode, and the optimization and selection have respective advantages and disadvantages. Orthogonal mode of D2D: the control of the base station can be fully utilized, but because unused resources of cellular communication are used, the communication capacity is still limited to a certain extent; the D2D multiplexing mode is more flexible in resource use, can bring the improvement of communication capacity to the system, but introduces more complex interference; the MIMO diversity mode improves the quality of a communication link, and does not improve the data rate; the MIMO multiplexing method can significantly improve the service rate, but does not improve the link quality. The research of the prior art schemes is more and more to find a better solution in each service field, and trade off is made from the solution.
Under the background, the scheme of the invention combines the wireless resource sharing mode of 5G D2D and the MIMO working mode, and controls each other to complete the management of the wireless resource of 5G D2D and the MIMO working mode.

if the MIMO operation mode of the terminal is the multiplexing mode, performing step S22;
s22, the terminal preferentially selects the orthogonal mode to share the mobile cellular network resources.
Under the condition that the gNB does not issue the available resources of the D2D terminal, the requirement of the terminal on the service throughput and the monitoring of the D2D communication link quality can be monitored in real time according to the service conditions of the D2D terminal and the target D2D terminal, if the D2D terminal communication link quality is higher than a specific threshold value and the service throughput requirement is also higher than the specific threshold value, the D2D terminal preferentially selects the MIMO multiplexing mode to carry out data communication, and controls the D2D terminal to preferentially select the orthogonal mode to share the mobile cellular network resources. And when the monitored communication link quality of the D2D terminal is lower than a specific threshold, controlling the D2D terminal to preferentially select the MIMO diversity mode for data communication, and controlling the D2D terminal to preferentially select the multiplexing mode to share the mobile cellular network resources.
