Problems solved by technology

Although this method can improve the system capacity to a certain extent, because it does not jointly multiplex the uplink and downlink spectrum resources, and the Gale-Shapley algorithm only obtains weak Pareto optimum (weak Pareto optimum), there are still large user gaps in the network. room for performance improvement

Abstract

The present invention provides a resource allocation method for D2D communication with combined uplink and downlink channels in a cellular network. The minimum constraint value of the power under the preset constraint conditions; calculate all the optimal transmit power according to the Lambert W function and the minimum constraint value; find the optimal allocation of the cellular user to the D2D user based on the Kuhn-Munkres algorithm and all the optimal transmit power The best uplink channel resources, the best downlink channel resources allocated by cellular users to D2D users. The D2D user in the present invention adopts the way of joint multiplexing of uplink and downlink channels to further improve the spectrum utilization rate; and combines power control and channel allocation to implement a two-level resource allocation method to maximize the advantages of the D2D communication system; adopt cellular users and D2D The power allocation scheme jointly adjusted by users can maximize the energy efficiency of D2D users.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for resource allocation of D2D communication in which upper and lower channels are combined in a cellular network. Background technique [0002] As one of the key technologies of 5G, device-to-device (Device-to-Device, hereinafter referred to as D2D) communication is a short-distance communication technology that directly performs data communication without forwarding by a base station. D2D communication technology allows adjacent mobile terminals to use operator-licensed spectrum to directly perform point-to-point data transmission, so that local services can be upgraded in the network without building additional infrastructure. The introduction of D2D communication technology in the cellular network can bring many benefits, but the introduction of D2D communication in the cellular network, the multiplexing of cellular user channels will cause serious i...
