Resource allocation method, system, device with base station function, and terminal

Abstract

The present invention provides a resource configuration method and system for terminal direct connection communication, a device with base station function, and a terminal, and is suitable for a resource configuration method for terminal direct connection communication of a device with base station function, including: obtaining The usage of time-frequency resources of the device with base station function, and / or the state information of each D2D terminal within the coverage of the device with base station function; according to the usage of time-frequency resources of the device with base station function and / or each The state information of each D2D terminal determines the configuration mode for configuring time-frequency resources for each D2D terminal; allocates time-frequency resources for direct terminal communication to each D2D terminal according to the configuration mode, for each D2D terminal The terminal performs direct terminal communication according to the allocated time-frequency resources. The technical solution of the present invention can effectively reduce the probability of D2D communication interruption, ensure the continuity of D2D communication services, and at the same time ensure that D2D terminals have higher communication quality when performing D2D communication.

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 basis of cellular network. facilities) 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, with...

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
