    摘要： A transmission method or a transmission apparatus maps input information of K+n bits to a polar code, encodes the input information on the basis of the polar code, and transmits the encoded input information. The input information includes n parity check bits. n1 bits of the n parity check bits are mapped to least reliable bit positions of K+n bit positions of the polar code, and n−n1 parity check bits (where n−n1>0) are mapped to n−n1 bit positions having a minimum row weight among K+n−n1 bit positions excluding the n1 least reliable bit positions among the K+n bit positions.

    摘要： An encoding method on the basis of a polar code in order to support an HARQ according to the present embodiment comprises the steps of: configuring, an input vector for retransmission, which has a length of N and is applied to a mother matrix predetermined on the basis of a polar code, by a wireless device, wherein the input vector is defined on the basis of a first index set for an optimized position of an information bit having a length of K, a second index set for a position of a bit to be punctured among encoded bits generated on the basis of the mother matrix, and a third index set for a position of at least one unknown frozen bit associated with an information copying scheme; and performing encoding on the basis of the input vector and the mother matrix, by the wireless device.

    摘要： Disclosed are a method for dividing a carrying block of a Low Density Parity Check (LDPC) code and an apparatus therefor. The method for dividing a LDPC code of the present disclosure can obtain a high throughput by using a limited size of shifting network. Moreover, it is possible to prevent degradation in performance due to a minimum size of code block by performing shortening for a large size of code block while minimizing the number of code blocks. Furthermore, in selection of a minimum size of code block, since a minimum size of code block is selected on the basis of shortening for a relatively large size of code block, it is possible to increase the size of the minimum size of code block.

    摘要： A method for transmitting an uplink signal is discussed. The method performed by a narrowband-internet of things (NB-IoT) device includes determining a time resource unit based on an uplink subcarrier spacing for transmitting the uplink signal; and transmitting the uplink signal on the time resource unit to a base station. Further, the time resource unit includes one or more slots including a plurality of symbols, based on the uplink subcarrier spacing, a predetermined time period in the one or more slots is not used for the transmission of the uplink signal, and the uplink carrier spacing includes 3.75 kHz.
