METHOD FOR DEVICE-TO-DEVICE COMMUNICATION AND A CORRESPONDING CONTROL METHOD

摘要

The prior art does not prescribe how to divide a control plane among network elements in a D2D communication under cellular architecture. To fill the technological gap, the present invention provides a method of performing the D2D communication and a corresponding control method, wherein a protocol signaling and protocol stack function of a media access (MAC) layer are implemented in a UE performing the D2D communication, and a control function is implemented by a master UE without introducing the base station, thereby reducing complexity of the base station and avoiding delay caused by the control of the base station; and wherein a protocol signaling and protocol stack function of a radio resource management (RRC) layer are implemented in the base station and the UE, and the control function is implemented by the base station and the base station performs mobility management.

1. A method of performing device-to-device (D2D) communication in a user equipment (UE), wherein the method comprises:
directly exchanging with another UE signaling of a media access layer for the D2D communication; implementing locally at the UE protocol stack function of the media access layer for the D2D communication; and: directly exchanging with a base station signaling of a radio resource control layer for the D2D communication; implementing locally at the UE protocol stack function of the radio resource control layer for the D2D communication.
