Method and apparatus for processing UCI and method for transmission thereof based on MIMO system

摘要

The present invention provides a method and apparatus for processing uplink control information (UCI) and a method for transmitting the UCI based on a multiple input multiple output system, which processing method comprises: repeating ACK/NACK source bits and/or rank indicator (RI) source bits in the uplink control information to form M groups, with each group corresponding to a code word (S302), wherein M is the total number of code words; carrying out channel encoding on the ACK/NACK source bits and/or RI source bits of each code word to obtain QACK*Li output bits (S304), wherein QACK is the channel encoding output bits corresponding to each layer in a certain code word, L is the total number of layers, and the layer number corresponding to the i-th code word is Li; and multiplexing and interleaving the output bits and the data bits of the corresponding code word (S306). The present invention solves the problems of transmission and channel encoding of the ACK/NACK and/or RI in the multiple input multiple output (MIMO) system, and at the same time takes into account high load situations and backward compatibility.

1. A method for processing uplink control information (UCI) based on a multiple input multiple output (MIMO) system, which comprises:
repeating Acknowledgement/Negative Acknowledgement (ACK/NACK) source bits and/or rank indicator (RI) source bits in the uplink control information to form M groups, with each group corresponding to a code word, wherein, M is the total number of code words; performing channel coding on the ACK/NACK source bits and/or RI source bits corresponding to each code word to obtain QACK*Li output bits, wherein, QACK is the number of channel coding output bits corresponding to each layer in a certain code word, L is the total number of layers, and the number of layer corresponding to the ith code word is Li; and multiplexing and interleaving the output bits and the data bits of the corresponding code word; wherein, the channel coding mode is determined in accordance with the number of ACK/NACK source bits and/or RI source bits corresponding to each code word and the ACK/NACK source bits and/or RI source bits are coded with the determined coding modes, wherein, if the number of the ACK/NACK source bits and/or RI source bits is smaller than A, such source bits are coded repeatedly after inserting one or more placeholders to obtain QACK output bits; and if the number of the ACK/NACK source bits and/or RI source bits is greater than or equal to A, and smaller than or equal to B, a RM (32, O) code is adopted for channel coding; if QACK>32, the coded bits are cycled and repeated to obtain QACK output bits; wherein, A
