FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used in mobile communication systems. A base station is configured to communicate with a plurality of mobile stations. The base station transmits a downlink frame to a first mobile station. The downlink frame comprises frequency-time resource elements allocated in a plurality of physical resource blocks, transmits the plurality of physical resource blocks in sets with a size of the set which depends on the system bandwidth configuration, and uses the same precoder for all physical resource blocks in the same set. The size of the set ranges from one physical resource block to three physical resource blocks.
EFFECT: high transmission channel throughput.
