RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD Russian patent published in 2017 - IPC H04B1/707 H04B1/7075 H04J1/00 

FIELD: radio engineering, communication.

SUBSTANCE: for the second symbol and the sixth symbol of the ACK/NACK signal that are multiplexed by the RS channel quality indicator (CQI), (+, +) or (-, -) are applied to the partial sequence from the Walsh sequence. For RS CQI, transmitted by the mobile station, + is added as a RS phase of the second symbol, and - is added as a RS phase of the sixth symbol. The base station (100) receives the multiplexed signals from the ACK/NACK signals and the CQI signals transmitted from the plurality of mobile stations. The RS synthesis unit (119) performs the synthesis by aligning the RS phases with the CQI.

EFFECT: improving the reception performance of the channel quality indicator, even when there is a delay in the propagation path, a transmission synchronization error occurs, or residual interference is generated between the cyclic shift values of the different ZC sequences.
