Cellular user clustering communication method and system as well as eNodeB and terminal

Abstract

The invention discloses a cellular user clustering communication method and system, an eNodeB and a terminal and relates to the field of mobile communication. The method comprises the following stepsthat the eNodeB establishes at least one cluster according to the position distribution relationship of a user terminal and determines a cluster head terminal and cluster member terminals, which belong to the cluster; the eNodeB allocates a cluster ID and cluster channel resources to the cluster head terminal; and the cluster head terminal receives a request for establishing a D2D connection between the cluster member terminals and allocates the cluster channel resources to the D2D connection in order to enable the cluster member terminals to communicate through the cluster channel resources.According to the method, the system, the eNodeB and the terminal, the user terminals in a cell are divided into a plurality of user clusters according to the positions, the resources are allocated according to the clusters, the cluster head provides intra-cluster information aggregation broadcast and realizes direct communication of the intra-cluster users, autonomous clustering and device-to-device communication can be achieved, the requirements of services for transmission characteristics, such as communication delay and reliability, are met, and the resource utilization efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cellular user clustering communication method, system, eNodeB, and terminal. Background technique [0002] With the development of the mobile Internet and the Internet of Things, various new types of mobile data services continue to emerge, which put forward new performance requirements for mobile communication network technologies. For example, the Internet of Vehicles service requires that the mobile communication network needs to support low-latency rapid response and communication between mobile users who are close to each other. huge challenge. Traditional mobile communication networks based on cellular communication, such as the 4th generation mobile communication system LTE-A (Long Term Evolution Advanced, long-term evolution technology upgrade version) system includes two levels of core network and radio access network, in which the radio access ne...

Problems solved by technology

The eNodeB-based cellular networking structure realizes the multiplexing of spectrum resources at the cell level and improves the utilization efficiency of spectrum resources. However, communication between users must be completed through eNodeB to complete access and data forwarding, especially when a large number of users initiate service requests at the same time. , the system scheduling cycle increases, it is difficult to meet the requirements of low-latency applications for communication transmission delay between users, and in weak coverage areas such as cell edges, it is difficult to ensure reliable communication between users
