A packet processing technique can include receiving a packet, and parsing the packet based on a protocol field to generate a parse result vector. The parse result vector is used to select between forwarding the packet to a virtual machine executing on a host processing integrated circuit, forwarding the packet to a physical media access controller, multicasting the packet to multiple virtual machines executing on the host processing integrated circuit, and sending the packet to a hypervisor.

A method performed by a network node comprises transmitting a transmission of system information. The transmission comprises coded bits obtained by reading from a circular buffer. The transmission is transmitted in a first set of subframes corresponding to subframes #4 of a plurality of radio frames. The method further comprises transmitting an additional transmission of the system information. The additional transmission comprises additional coded bits obtained by continuing reading from the circular buffer. The additional transmission is transmitted in a second set of subframes corresponding to subframes of the plurality of radio frames other than subframes #4.

A data processing method, an apparatus, and a device are disclosed. The data processing method may be performed by a first communications device, and the first communications device is a transmit end of encoded data. The first communications device may send a high-order signal to a second communications device by using a plurality of parallel channels, and information bits in the parallel channels are arranged in a specified order. The method helps improve a transmission rate in a parallel channel transmission scenario, and helps the second communications device perform correct decoding.

Techniques are described for wireless communication. One method includes segmenting a payload into a plurality of code blocks; generating, for each code block, a cyclic redundancy check (CRC); encoding each code block and associated CRC in one or more codewords of a plurality of codewords; and transmitting the codewords. The encoding is based at least in part on a low density parity check code (LDPCC) encoding type. Another method includes receiving a plurality of codewords associated with a payload encoded using a LDPCC encoding type; decoding a set of the codewords associated with the first payload and a CRC; and transmitting one of an acknowledgement (ACK) or a non-acknowledgement (NAK) for the set of the codewords.

A method for decoding data by an electronic device (100) is provided. The method includes receiving, by the electronic device (100), encoded data. The method includes determining, by the electronic device (100), a sparsity of a plurality of Machine Learning (ML) models (301, 302) of a turbo decoder (150) of the electronic device (100) for decoding the encoded data based on Quality-of-Service (QoS) parameters. The method includes decoding, by the electronic device (100), the encoded data using the turbo decoder (150) based on the determined sparsity.

A system includes a first encoder configured to receive first input bits and generate a first stream of first bits based on the first input bits, a bit generator configured to receive second inputs bits and generate a second stream of second bits based on the second input bits, and a PAM4 transmitter configured to receive the first stream of first bits and the second stream of second bits, and generate PAM4 symbols based at least on the first stream of first bits.

In data communications, a suitably designed contrast coding scheme, comprising a process of contrast encoding (108) at a transmitter end (101) and a process of contrast decoding (120) at a receiver end (103), may be used to create contrast between the bit error rates ‘BERs’ experienced by different classes of bits. Contrast coding may be used to tune the BERs experienced by different subsets of bits, relative to each other, to better match a plurality of forward error correction ‘FEC’ schemes (104, 124) used for transmission of information bits (102), which may ultimately provide a communications system (100) having a higher noise tolerance, or greater data capacity, or smaller size, or lower heat.

A method for processing a data block by a user equipment in a wireless communication system comprises generating tail bits of 18 bits by performing trellis termination in a turbo encoder of code rate 1/5 containing a plurality of constituent encoders; and deploying the tail bits of 18 bits to 5 encoded bit sequences of the turbo encoder according to a prescribed rule, wherein 4 tail bits are deployed to a systematic bit sequence among the 5 encoded bit sequences according to the prescribed rule, and 4 tail bits are deployed to each of specific 2 parity bit sequences among 4 parity bit sequences according to the prescribed rule.

Provided are a data checking method and device. The method includes: receiving a transmission signal containing a first data block and transmitted by a transmission node, wherein the length of the first data block is N bits, the first data block is generated by performing an FEC encoding on a second data block which has a length of K bits, and the second data block is generated by performing a CRC encoding on a third data block which has a length of L bits, where N, K and L are all positive integers, and N≧K>L; obtaining a first estimation data block of the first data block according to the transmission signal, and obtaining a second estimation data block of the second data block according to the transmission signal; and checking the third data block according to a relationship between the first estimation data block and an FEC code space and/or a CRC check result of the second estimation data block. By means of the technical solution provided in the present disclosure, the problems that a transmission rate decreases due to the fact that a CRC check code is too long and a false detection rate cannot be ensured due to the fact that the CRC check code is too short are solved.
