    Abstract: An apparatus determines a code block size (CBS) of information bits contained in a codeword of low-density parity check (LDPC) coding. The apparatus compares the CBS with at least one threshold, determines, based on a result of the comparison, a Kb number and determines a Kp number based on a code rate and the Kb number. The apparatus generates a parity check matrix. An information portion of the parity check matrix is a first matrix formed by M number of second square matrices. M is equal to Kp multiplied by Kb. A total number of columns in the Kb number of second square matrices is equal to a total number of bits of the CBS. One or more matrices of the M number of second square matrices are circular permutation matrices. The apparatus operates an LDPC encoder or an LDPC decoder based on the parity check matrix.

    Abstract: Concepts and schemes pertaining to information coding for mobile communications are described. A processor of an apparatus encodes data to provide encoded data. The processor also transmits the encoded data to a network node of a wireless network. In encoding the data, the processor encodes the data with a low-density parity-check (LDPC) code to provide LDPC-coded data. Moreover, the processor processes the LDPC-coded data with a forward error correction (FEC) robustness enhancement function to provide the encoded data. The FEC robustness enhancement function includes an interleaving function that interleaves the LDPC-coded data to provide the encoded data, an interlacing function that interlaces the LDPC-coded data to provide the encoded data, or a bit-reordering function that reorders bits of the LDPC-coded data to provide the encoded data.

    Abstract: A transceiver architecture with combined digital beamforming and analog/hybrid beamforming is proposed. Digital beamforming is used for beam training with reduced overhead (switching time). It is beneficial to estimate all UE's angle of arrival (AoA) at the same time. In addition, the pilot/training signals are transmitted in a narrow band to reduce complexity. Analog/hybrid beamforming is used for data transmission with high directive gain and low complexity. The value of beamforming weights (phase shifter values) in analog domain can be based on the estimation of AoA from beam training. By using digital beamforming for beam training, combined with analog/hybrid beamforming for data transmission, effective beamforming is achieved with reduced overhead, complexity, and cost.
