RADIO BASE STATION AND USER EQUIPMENT AND METHODS THEREIN Russian patent published in 2019 - IPC H04L5/00 H04B1/69 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to transmitting, in UE, uplink control information in time slots in a subframe over a radio channel to a BS. To achieve the technical result, control information is comprised in a block of bits, which the UE maps to a sequence of complex valued modulation symbols and block-spreads the sequence of complex valued modulation symbols across Discrete Fourier Transform Spread - Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. Spreading sequence is applied to a sequence of complex valued modulation symbols, to achieve a block-spread sequence of complex valued modulation symbols. UE transforms the block-spread sequence of complex valued modulation symbols per DFTS-OFDM symbol. Matrix that depends on a DFTS- OFDM symbol index and/or slot index is applied to the block-spread sequence of complex valued modulation symbols. UE transmits the block-spread sequence of complex valued modulation symbols that has been transformed over a radio channel to the BS.

EFFECT: technical result is achieving high transmission performance.
