    Abstract: A processor of an apparatus establishes a wireless communication link with at least one other apparatus via a transceiver of the apparatus. The processor wirelessly communicates with the other apparatus via the wireless communication link by: selecting a first shift-coefficient table from a plurality of shift-coefficient tables; generating a QC-LDPC code using a base matrix and at least a portion of the first shift-coefficient table; selecting a codebook from a plurality of codebooks embedded in the QC-LDPC code; storing the selected codebook in a memory associated with the processor; encoding data using the selected codebook to generate a plurality of modulation symbols of the data; and controlling the transceiver to multiplex, convert, filter, amplify and radiate the modulation symbols as electromagnetic waves through one or more antennas of the apparatus to transmit the modulation symbols of the data to the other apparatus via the wireless communication link.

    Abstract: A method of cross component carrier (Cross-CC) beam management is proposed. A transceiver uses multiple CCs' channel measurements to obtain a beam vector such that better performance can be achieved by utilizing wideband channel. The transceiver derives the beam vector by using the channel measurements of a set of selected CCs applied with a carrier weight factor. The transceiver utilizes beam management reference signal (BM-RS) of the set of selected CCs to derive the beam vector, e.g., an optimal beam. In one embodiment, the carrier weight factor can be the number of BM-RS REs of each CC. In another embodiment, the channel measurements can be SNR/RSRP, and the carrier weight factor can be the SNR/RSRP of each CC.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a configuration specifying an initial aggregated bandwidth W0 carried on C0 component carriers on which a reception unit (RXU) of the UE is to receive signals. The UE determines a total bandwidth WTOT on which the UE is capable of receiving signals. The UE determines, based on WTOT and W0, an initial hardware limit of Q0′ RXUs that the UE is allowed to activate concurrently. The UE determines an adjusted aggregated bandwidth W1 carried on C1 component carriers on which an RXU of the UE is to receive signals based on a channel condition between the UE and the base station.

    Abstract: Aspects of the disclosure provide an apparatus that includes transmitting circuit and processing circuit. The transmitting circuitry is configured to transmit wireless signals. The processing circuitry is configured to encode a set of information bits with a code that is configured for incremental redundancy to generate a code word that includes the information bits and parity bits, buffer the code word in a circular buffer, determine a start position in the circular buffer based on a redundancy version that is selected from a plurality of redundancy versions based on a scenario evaluation of a previous transmission associated with the set of information bits, and transmit, via the transmitting circuitry, a selected portion of the code word from the start position.

    Abstract: Concepts and schemes pertaining to location of interleaver with low-density parity-check (LDPC) code are described. A processor of an apparatus encodes data to provide a stream of encoded data. The processor also rate matches the encoded data to provide a rate-matched stream of encoded data. The processor further interleaving the rate-matched stream of encoded data. In rate matching the encoded data, the processor buffers the stream of encoded data in a circular buffer, with the circular buffer functioning as a rate matching block that rate matches the stream of encoded data. In interleaving the rate-matched stream of encoded data, the processor performs bit-level interleaving on the rate-matched stream of encoded data to provide a stream of interleaved data.
