FIELD: wireless communication.
SUBSTANCE: mentioned technical result by creating a codebook structure that provides support for more than 32 CSI-RS (Channel State Information reference signals) antenna ports and more than 8 MIMO layers per UE and adapting the used PM matrix (precoding matrix) to optimize the use of the transmission power available at the base station due to existing limitations.
EFFECT: ensuring the implementation of precoding with an extension to support systems with ultra-large antenna arrays, as well as flexible optimization of the use of base station transmit power when forming a radiation pattern for DL transmission, which generally leads to increased operating efficiency in scenarios with EIRP (Effective Isotropic Radiated Power) restrictions.
