Abstract  Abstract

FIELD: radio engineering communication.SUBSTANCE: invention relates to wireless communication systems and is intended for precoding and using parameterised codebook subsets which can be used to limit codebook choices for different multiple input-multiple output (MIMO) operating modes. The method provides advantages for sending precoder selection feedback from a second transceiver to a first transceiver used as precoding recommendations. The second transceiver generates two types of precoder selection feedback depending on whether the second transceiver operates in a first or second feedback mode depending on whether the precoder selection feedback is sent on a data channel or control channel respectively. Preferably in the first feedback mode the second transceiver selects precoders based on DFT from a set of precoders based on DFT providing a first spatial resolution for beam-forming on the first transceiver and in the second feedback mode selects from a subset the same precoders based on DFT wherein said subset provides a lower second spatial resolution for beam-forming on the first transceiver.EFFECT: high rate of data transmission.12 cl 8 dwg
