    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 N 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: Methods, apparatus and systems for determining a transport block size in a wireless communication are disclosed. In one embodiment, a method performed by a wireless communication device is disclosed. The method comprises: receiving control information from a wireless communication node, wherein the control information includes a plurality of transmission parameters related to transport blocks to be transmitted between the wireless communication device and the wireless communication node; calculating an intermediate transport block size (TBS) for the transport blocks based on the plurality of transmission parameters; modifying the intermediate TBS to generate a modified TBS in response to an event that the intermediate TBS is smaller than a threshold; and determining a final. TBS for the transport blocks based on a TBS that is closest to the modified TBS, among TBSs that are in a quantized set and not smaller than the modified TBS.

    Abstract: Methods and Apparatus for processing data encoded by low density parity check (LDPC) in a communication system are disclosed herein. In one embodiment, a method performed by a first node is disclosed. The method comprises: encoding an information bit sequence based on an LDPC coding scheme to obtain an encoded bit sequence; generating a master bit sequence based on the encoded bit sequence; selecting a subset of the master bit sequence according to a rate matching rule to obtain a rate matched bit sequence; interleaving the rate matched bit sequence according to a predetermined index sequence to obtain a to-be-transmitted bit sequence; and transmitting the to-be-transmitted bit sequence to a second node.
