DEVICE TO DEVICE COMMUNICATION METHOD USING PARTIAL DEVICE CONTROL

摘要

A device to device (D2D) communication method based on a partial device control is disclosed. According to the present invention, the D2D communication method and, particularly, to a partial device control method for D2D communication a relates to, and provides a D2D resource allocation and release method, a D2D HARQ process operating method, a link adaptation method comprising D2D link power control and adaptive modulation and coding (AMC), a D2D control information signaling method, a CSI reporting method for D2D communication, and contents of a CSI report. The present invention can enhance the advantages of and compensate for the disadvantages of both methods through the combination of a base station control a base station control type D2D communication method and a device control type D2D communication method.

主权项

1. A device-to-device (D2D) communication method as an operation method of a first user equipment (UE) for measuring and reporting channel state information (CSI) on D2D communication in which the first UE and a second UE participate, the D2D communication method comprising:
at a request of a base station, measuring and reporting first CSI on a whole or a part of an entire cellular band to the base station; receiving D2D resource allocation information based on the first CSI from the base station; and measuring and reporting second CSI on D2D resources based on the D2D resource allocation information to the second UE.
