Abstract: 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.

Abstract: 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.

Abstract: Polar Codes for Downlink Control Channels for Wireless Networks A technique is provided for decoding downlink control information that was encoded using polar encoding, the technique including: attempting, based on an initial assumption by a user device of a segmented downlink control information, to decode a first codeword provided via a user device-specific resource, the first codeword including a first downlink control information segment and a pointer to a second downlink control information segment of a segmented downlink control information; decoding, if the attempting to decode is successful, based on the pointer, a second codeword that includes the second downlink control information segment of the segmented downlink control information; and otherwise, if the attempting to decode is unsuccessful, making an assumption of a non-segmented downlink control information and decoding a third codeword to obtain a non-segmented downlink control information.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for radio link adaptation. In an example implementation, the method may include a user equipment receiving a channel quality report configuration from a network node, the channel quality report configuration including a first transport block size. The method may further include determining a channel quality indicator based at least on the first transport block size and transmitting the channel quality indicator to the network node. In another example implementation, the method may include a network node determining a first transport block size, the first transport block size being a target transport block size, and transmitting a channel quality report configuration to a user equipment, the channel quality report configuration including the first transport block size. The method may further include receiving a channel quality indicator from the user equipment, the channel quality indicator determined at the user equipment based at least on the first transport block size transmitted from the network node.
