METHOD FOR MULTIUSER CHANNEL QUALITY INDICATOR FEEDBACK IN COMMUNICATION SYSTEM, TRANSMISSION POINT DEVICE AND USER DEVICE

摘要

FIELD: radio engineering, communication.SUBSTANCE: invention relates to wireless communication and can be used in multiple-user multiple-input multiple-output (MIMO) communication systems A user device in a communication system, which includes a transmission point and a plurality of user devices, comprises: a receiving module configured to receive a message indicating a resource for which interference is measured, wherein the resource is indicated using a subset of subframes, a processing module configured to calculate a channel quality indicator (CQI) based on said message, and a transmitting module configured to transmit the CQI to the transmission point.EFFECT: high efficiency of link adaptation with negligible downlink overhead.18 cl, 8 dwg
