Abstract

The invention provides a resource allocation method, a resource allocation system, a terminal and a base station for direct communication of the terminal. The resource allocation method applicable to the terminal and used for direct communication of the terminal comprises the steps: detecting a time-frequency resource already occupied by other D2D terminals when a data transmission service is needed; selecting the time-frequency resource for processing the data transmission service according to the time-frequency resource occupied by other D2D terminals and the attribute information of the data transmission service. According to the technical scheme, the problem of the confliction in the allocation of the time-frequency resource can be avoided, the resource selection problem when the time-frequency resource is insufficient can be effectively solved, and reasonability in allocation and application of the resource can be realized.

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 cellular network. Infrastructure) 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 going through t...
