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...
