An apparatus comprising circuitry for performing: receiving a configuration message from a base station, wherein the configuration message includes instructions to use at least one first path for uplink transmission of a first group of data packets, and to use at least one configured grant in at least one second path for uplink transmission of duplicate packets of the first group of data packets; and in response to determining that at least one event has occurred, modifying at least one condition of the at least one configured grant for the uplink transmission of the duplicated packets.

A method of communicating between nodes in a network where a node receives a sequence of symbols that will form a packet on a first communications channel and has a planned packet that it would send on a second communications channel. A destination is encoded into an arbitration portion of a header sequence of the packet, the header sequence comprising a sequence of symbols. The transmission on the second communications channel is as per the planned packet, for as long as the symbols of the planned packet match the symbols being received on the first channel. An arbitration decision is made when the symbols do not match, with the node either continuing to send the rest of the planned packet, or the rest of the packet being received on the first communications channel.

A data distribution method, a data aggregation method, and related apparatuses are disclosed. The data distribution method may include: receiving a first packet stream; dividing the first packet stream to obtain a first data block stream; sending the first data block stream to a first circuit; processing, by the first circuit, the first data block stream to obtain a first data stream; distributing, by the first circuit, the first data stream to N1 second circuits of M second circuits in a PT-W, where M is greater than N1, N1 is a positive integer, and M is a positive integer; and processing, by the N1 second circuits, the received first data stream to obtain N1 first code streams. The technical solutions provided by the embodiments of the present application help to meet a requirement for complex bandwidth configuration and extend an application scenario.

Provided is a high-speed communication system with the high reliability and the low latency under New Radio (NR). A base station device includes a plurality of distributed units (DU) that transmit and receive radio signals, and a central unit (CU) that controls the plurality of DUs. The CU duplicates a downlink packet addressed to a communication terminal device, and forwards the duplicated downlink packet to each of at least two DUs among the plurality of DUs. Each of the at least two of the DUs transmits, to the communication terminal device by the radio signal, the downlink packet obtained from the CU. Upon redundant receipt of the downlink packets, the communication terminal device removes a redundant downlink packet in accordance with a predefined downlink packet removal criterion.

Embodiments provide apparatuses, methods and computer programs for mobile communication systems comprising base station and mobile transceivers. An apparatus for a base station transceiver (and/or a mobile transceiver) of a mobile communication system, comprises a transceiver module to communicate with the mobile transceiver (and/or base station transceiver) using first and second communication channels, wherein the first channel is more reliable than the second channel. The apparatus further comprises a controller module to control the transceiver module, and to provide a data service to the mobile transceiver (and/or base station transceiver). The data service comprises first and second data packets, wherein the first data packets comprise information related to core data of the data service, and wherein the second data packets comprise information related to optional refinement data for the data service. The first data packets use the first channel, and the second data packets use the second channel.

Systems and devices can include a first port of a first device coupled to a second port of a second device across a multi-lane link. The first port can augment a data block with error correcting code by distributing error correcting code evenly across each lane of the data block, wherein each lane of the data block includes a same number of error correcting code. The first port can transmit the data block with the per-lane error correcting code to the second port across the multi-lane link. The second port can determine error correcting code based on the error correcting code bits received in the data block, and perform error correction on the symbols of the data block based on the error correcting code received.

Methods, systems, and devices are described herein for using codewords to detect or correct errors in data (e.g., data stored in a memory device). A host device may generate one or more codewords associated with data to be stored in the memory device. In some cases, the host device may generate one or more codewords for error detection and correction (e.g., corresponding to data transmitted by the host device to the memory device). In some cases, the host device may transmit the codewords and the associated data using an extended (e.g., adjustable) burst length such that the one or more codewords may be included in the burst along with the data. Additionally or alternatively, the host device may transmit one or more of the codewords over one or more channels different than the one or more channels used to transmit the data.

A data transmission device includes a de-interleaver configured to receive, from a host device at a first data rate, a data stream including encoded data, de-interleave the data stream into a plurality of forward error correction (FEC) data streams, and output the plurality of FEC data streams at a second data rate less than the first data rate. Each of a plurality of interleavers is configured to interleave a respective one of the plurality of FEC data streams into an intermediate data stream including first data blocks and second data blocks. An encoder module configured to generate, for each of the intermediate data streams, FEC blocks including a first parity section and a first data section, the first parity section including a first parity bit corresponding to the first data blocks and a second parity bit corresponding to the second data blocks, and the first data section including the first data blocks and the second data blocks, and output the FEC blocks at the second data rate.

A method performed by a node, for handling one or more member streams split from a stream of frames. The node supports at least replication function and one elimination function, to process the one or more member streams. The node operates in a communications network. The node assigns an indication to a frame of one or more frames comprised in a first member stream outgoing from the at least one elimination function. The indication is the same in every frame of the one or more frames. The indication identifies the first member stream as an output member stream in the stream. The node forwards the first member stream outgoing from the at least one elimination function, identified by the indication, to another function supported by the node, or to another node.

A data processing method includes: inserting multiple alignment markers (AMs) into a first data stream, where the first data stream is a data stream that is transcoded and scrambled after being encoded at a physical layer; adaptively allocating the first data stream that includes the multiple AMs to multiple physical coding sublayer (PCS) lanes to obtain second data streams; performing forward error correction (FEC) encoding on the second data streams on the multiple PCS lanes to obtain third data streams; and delivering the third data streams to multiple physical medium attachment (PMA) sublayer lanes according to an input bit width of a serializer/deserializer (SerDes) to obtain multiple fourth data streams, each fourth data stream includes at least one complete and continuous AM, and the at least one AM is an AM in the multiple AMs.
