FIELD: information technologies.
SUBSTANCE: in one version indication of preliminary coding control (PCI), range and channel quality indication (CQI) for data transfer from a transmitter to a receiver may be determined by assessment of various assumptions. Based on PCI, the range and CQI a message may be generated. PCI may include a matrix or a vector of preliminary coding for use in data transfer. CQI may include at least one value of CQI at least for one transport unit for sending in the data transfer. The range and CQI may be combined on the basis of conversion. For instance, CQI may include one value of CQI and get into the first range of values, if the receiver prefers one transport unit. CQI may include two values of CQI and get into the second range of values, if both transport units are preferable.
EFFECT: efficiency of sending feedback information.
