    Abstract: Provided is a rate matching method and device for a Polar code. The method includes: concatenating K information bits and (N−K) frozen bits to generate a bit sequence of N bits, and encoding the bit sequence of N bits by means of a Polar code encoder with a generator matrix of size N×N to generate an initial bit sequence {S0, S1, . . . , SN−1} of bits, where K and N are both positive integers and K is less than or equal to N; dividing a circular buffer into q parts, selecting bits from the initial bit sequence {S0, S1, . . . , SN−1} in a non-repeated manner, and writing the bits into the q parts of the circular buffer according to a predefined rule, where q=1, 2, 3 or 4; and sequentially selecting a bit sequence of a specified length from a predefined starting position in a bit sequence in the circular buffer and taking the bit sequence of the specified length as a bit sequence to be transmitted.

    Abstract: Disclosed are a convolutional coded data sending method and apparatus. The method comprises: coding data bits of an input information block with convolutional codes, and combining the coded data bits into a circular buffer region; determining a starting position where data bits forming a to-be-transmitted data packet are read in the circular buffer region; and reading, from the starting position, the data bits having a specific length column by column in a column sequence to form the to-be-transmitted data packet, and sending the to-be-transmitted packet. The convolutional code data sending method and apparatus disclosed in the present invention can generate a to-be-transmitted data packet of a convolutional code having a flexible code rate.

    Abstract: Provided is a method and an apparatus for encoding CSI, a storage medium, and a processor, where the method includes: placing a first type of information bits of the CSI in a first type of position indexes of the position index set, and determining, from the indexes other than the first type of position indexes determined by the first type of information bits in the position index set, indexes of the second type of information bits of the CSI, indexes of the third type of information bits of the CSI, and indexes of the fourth type of information bits in the position index set; or placing the fourth type of information bits in the fourth type of position indexes of the position index set, and determining indexes of the first type of information bits, indexes of the second type of information bits, and indexes of the third type of information bits of the CSI in the position index set from indexes other than the fourth type of position indexes determined by the fourth type of information bits in the position index set. The present disclosure solves the problem that positions of various types of information in the CSI reporting cannot be reasonably mapped in the related art.
