FIELD: electrical communication engineering.
SUBSTANCE: invention relates to wireless communication networks. In the transmission method, user equipment (UE) transmits two transport units in accordance with a given number of levels and corresponding precoding indices, evolved Node B (eNB) transmits, when one of the transport blocks is lost, a negative acknowledgment for the lost transport block, and the UE sets a precoding index for the lost transport block by a predetermined value for repeated transmission of the lost transport block, while preserving the number of levels.
EFFECT: invention provides a method of transmitting/receiving and a device for a mobile communication system supporting MIMO over an uplink.
