Resource management method based on non-cooperation game for D2D communication

Abstract

The invention discloses a resource management method based on non-cooperation game for D2D communication and mainly aims to solve problems that power consumption is large, the spectrum utilization rate is low and the communication demand in the case of multiple intelligent terminals can not be met. The method comprises steps of 1), setting the simulation scene; 2), setting constraint conditions for a user according to the simulation scene; 3), constructing a combined cost function of the non-cooperation game under the constraint condition to perform game modeling for a D2D user; 4), adjustingthe cellular user power to obtain a cellular user power vector; 5), performing the non-cooperation game to obtain a power matrix according to the cellular user power vector by the D2D user; 6), determining the stability of the D2D user and cellular user joint power matrix; and 7), determining user power and spectrum distribution according to the power matrix. The method is advantaged in that underthe condition of simultaneous spectrum and power distribution, power consumption is reduced, the spectrum utilization rate is improved, and the method can be used in D2D communication of the 5G key technology.

Description

technical field [0001] The invention belongs to the field of communication technology, and relates to a resource allocation method, which can be used in D2D communication, a key technology of 5G, to improve spectrum utilization, reduce transmission delay in communication, reduce transmission power and increase information transmission rate. Background technique [0002] D2D communication means that the cellular system allows users with close physical locations to communicate directly under the control of the base station instead of being forwarded by the base station. This communication method can use scarce spectrum resources more efficiently, and has the advantages of low delay and low energy consumption due to the short communication distance. It is precisely because of the many advantages of D2D communication that it has received more and more attention both in the research field and in the industrial field. There are two working modes for D2D communication: dedicated m...

Problems solved by technology

[0004] "Resource sharing optimization for device-to-device communication underlying cellular networks" published by C.-H.Yu et al. (IEEE Trans.Wireless Communication, vol.10, no.8, pp.2752–2763, Aug.2011. ) is a centralized method for resource management in D2D communication. This method considers maximizing the total throughput of the system while ensuring the QoS of cellular users. Its shortcoming is that the research scenario is relatively simple, and only a pair of D2D Scenarios where only one cellular user can be multiplexed

Not only the interference brought by D2D to CUE is controlled, but also the interference between D2D users is also controlled. The shortcoming is that it does not solve the problem of sub-channel allocation

[0007] None of the above solutions can meet the communication needs when spectrum resources are scarce in the case of multiple intelligent terminals
