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.
