Abstract

The present invention provides a resource allocation method and system for direct communication of a terminal, the terminal, and a base station. The resource allocation method for direct communication of a terminal, applicable to the terminal, comprises: when it is determined that a data transmission service needs to performed, detecting a time-frequency resource occupied by another D2D terminal; and selecting, according to the time-frequency resource occupied by another D2D terminal and attribute information of the data transmission service, a time-frequency resource for processing the data transmission service. By means of the technical scheme of the present invention, the problem of the confliction in the allocation of time-frequency resources can be avoided, the resource selection problem when time-frequency resources are insufficient can be effectively solved, and accordingly resources are properly allocated and used.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular, to a resource configuration method for terminal direct communication, a resource configuration system for terminal direct communication, a terminal and a base station. 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 basis of cellular network. facilities) has gradually become an important technical point. D2D technology mainly includes D2D discovery (discovery stage) and D2Dcommunication (communication stage). D2D discovery and D2D communication are independent services. D2D communication allows two UEs to directly send and receive data through a specific channel (sidelink channel). transmission, without transmiss...
