specific Embodiment approach

[0065] Comparing the resource allocation between the B system and the A system, the difference is that both require the BS to perform overall control over the allocation of users and resources. The main difference is that the BS does not need to consider the cumulative interference at the BS. The total user capacity of the system does not depend on the analysis of the cumulative interference at the BS. The BS needs to consider how to perform multi-user resource scheduling between D2D users and cellular users. While ensuring the quality of service for D2D users and cellular users, it maximizes resource reuse and capacity expansion. The specific implementation is as follows:

[0066] Step 302: First, the BS predicts the user's location distribution based on the received user power or the location information uploaded by the user. According to the location distribution, there may be an interference relationship. D2D users and cellular users perform interference subdomain division (i...

Abstract

The invention provides a base-station (BS)-combined direct-through terminal optimized resource allocation method in a direct-through cellular system. In order not to interrupt the normal communication of traditional cellular subscriber links and obtain effective gain brought by device-to-device (D2D) direct-through technology, D2D subscribers are allowed to adopt a resource allocation manner that resources are selected by a D2D subscriber end when uplink and downlink resources of the cellular system are shared; at this time, the D2D subscribers only need to consider the interference to other cellular subscribers (CUs) arising from signals of the D2D subscribers; and meanwhile, a BS centralized-control manner is adopted to carry out resource allocation, the centralized-control advantage of a BS is exerted, a BS and D2D terminal combined optimization manner is fully utilized, and the advantages of the two allocation manners are exerted. The BS-combined direct-through terminal optimized resource allocation method in the direct-through cellular system has the advantages that the resource utilization ratio and availability of a coexistent system which is provided with the D2D direct-through technology are sufficiently improved, the multiplexing gain of the resources are maximally developed, the system capacity is increased, the service types are increased, and the quality of service is ensured; and many chances for resource multiplexing are developed under the condition of limited resources from a novel resource allocation viewing angle.

Description

technical field [0001] The invention relates to a method for optimal resource allocation of a base station in conjunction with a direct terminal in a direct cellular system, and relates to the design of an effective management scheme for resources in a system where D2D (Device to Device) direct technology and cellular coexist. Background technique [0002] As the demand for personal communication services increases, the performance requirements for mobile communication systems also increase, requiring network operators and infrastructure manufacturers to provide higher service quality and richer services from a system-level perspective. From the perspective of limited resources, we can develop more resource reuse opportunities, especially the re-development and utilization of spectrum resources. [0003] Under the condition of limited resources, collaboration among systems and resource sharing become a solution to improve resource utilization. On the premise that the spectr...
