FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a method of operating a secondary station which communicates with at least one primary station via MIMO transmissions. A method of operating a secondary station which communicates with at least one primary station via MIMO transmissions is characterised by that the secondary station signals a single precoding indicator representative of at least one set of recommended precoding coefficients to the primary station, wherein the single precoding indicator is common for a plurality of available MIMO transmission modes.
EFFECT: high data rate, reduced amount of resources needed to signal recommended precoding coefficients.
