Resource allocation method, device and terminal for D2D communication

Abstract

The invention provides a resource allocation method, device and terminal for D2D communication. The resource allocation method for D2D communication comprises the first step of determining whether the relay function for D2D communication needs to be provided for other terminals or not, the second step of configuring transmission resources for D2D communication to the other terminals when it is determined that the relay function for D2D communication needs to be provided for other terminals so that the other terminals can conduct D2D communication through the transmission resources. By means of the technical scheme, an auxiliary link for D2D communication can be fully utilized to conduct connection, so flexible configuration on the transmission resources of the other terminals is achieved, and the problem of allocation of the resources for D2D communication is effectively solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular, to a resource configuration method for D2D communication, a resource configuration device for D2D communication, and a terminal. Background technique [0002] The device to device direct communication technology (Device to Device, or D2D, is a technology for direct terminal communication introduced by 3GPP Rel-12, which allows user data transmission without passing through the infrastructure of the cellular network) means that user terminals (UE) can communicate directly D2D communication can be deployed within the coverage of the cellular network and / or outside the coverage of the network without the need for transmission or forwarding by equipment such as a base station (eNB). [0003] UE-NW (UE-to-Network) relay is a new feature introduced in D2D communication. It has the advantages of flexible deployment and can expand network coverage without adding existing n...

AI Technical Summary

Problems solved by technology

[0009] In the UE-NW relay working mode, some UEs are within the coverage of the network, and some UEs are outside the coverage of the network. The current D2D communication has not provided a special resource allocation method for this. If the existing method is still used, the remote If the UE uses the pre-configured resource pool, and the relay UE uses the resource pool configured by the eNB or is scheduled by the eNB, the D2D secondary link connection is not fully utilized, and there is a waste of the eNB resource configuration capability. At the same time, some Relay UE may be competent for resource configuration capabilities
