Identification of communication participants may be an important aspect of various communication systems. For example, fifth generation (5G) wireless communication systems may benefit from suitable recipient identification. A method can include obtaining data bits to be communicated to a target device. The method can also include obtaining identification bits corresponding to at least one of sender or receiver of the data bits. The method can further include multiplexing the data bits with the identification bits.

Recipient identification for fifth generation communication

A method including determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.

This document discloses a solution for error detection. According to an aspect, a method comprises: generating, by a first apparatus, a transport block and error detection bits for the transport block; generating, by the first apparatus, a first number of code block groups by using the transport block and the error detection bits, wherein the first number is two or higher and based on a number of code blocks a second apparatus is able to decode in parallel processing; generating, by the first apparatus, error detection bits for at least one of the code block groups; generating, by the first apparatus, a plurality of code blocks for each code block group, and causing transmission of the plurality of code blocks to the second apparatus.

Error detection and channel coding of transport blocks

A base matrix is applied to an LDPC coder. The base matrix includes multiple parts, each including multiple of rows and columns, and containing integers, each representative of an identity matrix cyclically shifted in accordance with the integer or representative of an all-zero matrix. At least two of the multiple parts are configured such that their respective column-wise combinations of rows represents a same starting vector, cyclically shifted or interleaved, with zero or more but not all integers not indicative of the all-zero matrix of the same vector substituted by integers indicative of the all-zero matrix. The at least two of the multiple parts are not identical. The applied base matrix is used for one of encoding data using the LDPC coder or decoding data using the LDPC coder.

Method and apparatus for vector based LDPC base matrix usage and generation

A method includes accessing information, and at least one of encoding or decoding the information using a parity check matrix based on a coding rate. A portion of a data part in the parity check matrix has been generated based on part or all of another matrix. Apparatus, computer programs, and computer program products are also described. The apparatus may be a wireless mobile device or a wireless network access node. A communication system may include one or more of the wireless mobile devices and one or more of the access nodes, each using a version of the method.
