Abstract

The invention provides a method and a device for allocation of device-to-device (D2D) resources. The method comprises the following steps that a master base station obtains D2D related information of a secondary base station; and the master base station sends D2D auxiliary information to user equipment (UE) according to the D2D related information, wherein the D2D related information is used for indicating the UE to use the D2D resources of the secondary base station to carry out D2D operation, and the D2D operation includes at least one of D2D discovery, D2D communication and D2D relay. Through the method and the device, a problem of allocation of the D2D resources of the UE under a dual connection architecture in the correlation technique is solved, so that the D2D operation, such as D2D discovery and / or D2D communication and / or D2D relay, can go smoothly.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a device-to-device D2D resource configuration method and device. Background technique [0002] With the development of wireless multimedia services, people's demand for high data rate and user experience is increasing, which puts forward higher requirements on the system capacity and coverage of traditional cellular networks. In a traditional LTE cellular network, the macro base station serves as the only network element on the access side to provide access services for UEs. In order to meet user requirements for higher data rates and improve spectral efficiency of cellular networks, 3GPP introduces a Low Power Node (LPN for short) as a supplement to a macro base station to provide access services for UEs. LPN has the characteristics of low cost, low power, and easy deployment. It usually has two deployment scenarios: hotspot deployment and enhanced coverage. It can effectivel...
