Abstract: A communication apparatus is disclosed including a processor that performs a first encoding procedure to generate a first sequence of encoded bits from a first sequence of bits, and performs a second encoding procedure to generate a second sequence of encoded bits from a sequence of known bits; and a second sequence of bits comprising the first sequence of bits and the first sequence of encoded bits; and a transmitter that transmits a signal generated from the second sequence of encoded bits, wherein the second sequence of encoded bits is determined based on a length of the second sequence of bits.

Abstract: A method is presented for transmitting uplink control information and a mobile station. The method for transmitting the uplink control information includes: adding padding bits to initial control information to generate uplink control information, where the initial control information includes first information having a same number of bits for RANKs of different channel matrices and second information having a same or different number of bits for RANKs of different channel matrices; and transmitting the uplink control information.

Abstract: Provided in embodiments of the present invention are a feedback method and communication device. The feedback method of the embodiment of the present invention comprises: receiving a data block including multiple code block groups; generating feedback information about the data block according to a receiving status of the multiple code block groups, the feedback information being used to indicate a respective transmission status of at least a part of the code block groups in the multiple code block groups; transmitting the feedback information.

Abstract: Disclosed are a method and an encoder for performing polar coding on an input data sequence to generate a polar code. The encoding method including: generating, based on a first order index set, a second order index set for parent code length of the polar code, each order index of the first or second order index set representing a priority order of transmitting an information bit in a bit position indicated by the order index relative to transmitting information bits at bit positions indicated by other indexes; spreading, according to the second order index set, the input data sequence to a data sequence with bit number equal to the parent code length; performing polar coding on the spread data sequence to generate the polar code.
