METHOD, SYSTEM, USER EQUIPMENT AND BASE STATION FOR TRANSMITTING UPLINK CONTROL INFORMATION

摘要

A method, system, user equipment and base station for transmitting uplink control information are disclosed in the present invention and belong to communication technology field. The method includes the steps of: according to a preset sorting rule, sorting Uplink Control Information (UCI) of each downlink carrier in X downlink carriers, wherein X is a positive integer and the X downlink carriers belong to a downlink activation carrier set of a user equipment; according to the first carrier set, calculating the number of modulation symbols occupied by the UCI of the user equipment; according to the number of modulation symbols occupied by the UCI of the user equipment, calculating bits of the UCI of the user equipment after Channel coding; according to the bits of the UCI of the user equipment after the Channel coding, after performing the Channel coding on the UCI of the sorted X downlink carriers, mapping the UCI to a Physical channel and transmitting it to a base station. The present invention solves the problem that an Evolved NodeB (eNB) produces a decoding error on the combine coded UCI.
