Resource configuration method and system, equipment with base station function and terminal

Abstract

The invention provides a resource configuration method and system for terminal direct communication, equipment with base station function and a terminal. The resource configuration method suitable for the equipment with the base station function and used for terminal direct communication comprises the following steps: acquiring use condition of time frequency resource of the equipment with the base station function, and / or status information of each D2D terminal in the coverage range of the equipment with the base station function; determining a configuration mode for configuring the time frequency resource for each D2D terminal according to the use condition of the time frequency resource of the equipment with the base station function and / or the status information of each D2D terminal; and distributing the time frequency resource for terminal direct communication for each D2D terminal according to the configuration mode so that each D2D terminal can perform the terminal direct communication according to the distributed time frequency resource. Through the adoption of the technical scheme provided by the invention, the D2D communication outage probability can be effectively reduced, the D2D communication service continuity is guaranteed, and meanwhile, the high communication quality in D2D communication of the D2D terminal is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a resource configuration method for terminal direct communication, a resource configuration system for terminal direct communication, a device with base station function, and a terminal. Background technique [0002] With the development of mobile terminal software and hardware technology and wireless communication technology, Device to Device (D2D) is a technology for direct terminal communication introduced by 3GPP Rel-12, which allows user data transmission without going through the cellular network. Infrastructure) has gradually become an important technical point. D2D technology mainly includes D2D discovery (discovery phase) and D2D communication (communication phase). D2D discovery and D2D communication are independent services. D2D communication allows two UEs to directly send data through a specific channel (sidelink channel). And transmission, without t...

AI Technical Summary

Problems solved by technology

[0004] At present, when 3GPP is discussing the D2D communication scheme based on direct scheduling, there are the following problems: when the macro network coverage of the UE is not good, it is possible that the UE that is in the connected state and communicates in mode A cannot obtain the information from the base station for a certain period of time. Mode A resources, during this period, if the UE still wants to use mode A resources, D2D communication cannot continue, resulting in the interruption of D2D communication
