METHOD AND DEVICE FOR INDICATING D2D RELATED INFORMATION AND DETERMINING D2D TRANSMISSION RESOURCE

摘要

A method and device for indicating D2D related information and determining D2D transmission resources, the method comprising: transmitting to a target base station a switching request message after determining cell switching for a device to device user equipment (D2D UE), the switching request message comprising D2D related information of the D2D UE; receiving a switching command transmitted by the target base station, the switching command comprising the resource allocation type and/or D2D transmission resource for the D2D UE in a target cell determined by the target base station based on the D2D related information; and transmitting the determined resource allocation type and/or D2D transmission resource to the D2D UE. The present invention solves the existing problem of how to determine D2D transmission resources during cell switching for a UE in D2N connection state.

1. A method for indicating, by a source base station, Device to Device (D2D) related information, the method comprising:
transmitting a handover request message comprising Device to Device (D2D) related information of a D2D UE to a destination base station upon deciding to perform a cell handover of the D2D UE; receiving a handover command transmitted by the destination base station, wherein the handover command comprises a resource allocation type and/or a D2D transmission resource of the D2D UE in a destination cell, determined by the destination base station according to the D2D related information; and transmitting the determined resource allocation type and/or D2D transmission resource to the D2D UE.
