CHANNEL STATE INFORMATION PROCESSING METHOD, DEVICE AND SYSTEM

摘要

A method, apparatus and system for processing channel state information are provided. The second channel state information of a second link is sent to a network node via a first link, wherein the first is a cellular communication link from a first device to the network node, and the second link is a D2D communication link between the first device and a second device capable of communicating with the first device. The transmission of channel state information is implemented during D2D communication in a cellular communication system, a criterion for scheduling D2D communication is consequentially provided, and the resource utilization rate of D2D communication is guaranteed. Moreover, the compatibility of D2D communication with cellular communication is achieved without obviously increasing the complexity of implementation and design of UE.
