Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a transport block for transmission that includes an information component and an error detection code. The base station may transmit a first encoded message during a first transmission time. The first encoded message may be obtained by encoding the transport block cyclically shifted a first bit length. The base station may transmit a second encoded message during a second transmission time. The second encoded message may be obtained by encoding the transport block cyclically shifted a second bit length. The relative time distance between the first and second transmission times may convey an indication of the difference between the first bit length and the second bit length.

Abstract: A method is provided for receiving broadcast signals. The broadcast signals are received. The received broadcast signals are demodulated by an Orthogonal Frequency Division Multiplex (OFDM) scheme, a signal frame is parsed from the demodulated broadcast signals, data is decoded in the parsed signal frame to output baseband packets, the baseband packets are output-processed to output link layer packets, and the link layer packets are de-encapsulated to output Transport Stream (TS) packets by inserting a header for each TS packet of which a header is deleted based on information of a header of the link layer packets.

Abstract: A method for the digital transmission of data blocks from a transmitting station to a receiving station, wherein delta information is generated at the transmitting end which indicates the positions at which a further data block differs from the preceding data block. The delta information is provided with error protection and is added to the further data block and is transmitted. The received first and the at least one extended further data block are stored in the receiving station. The delta information of the at least one extended further data block is then retrieved and applied to the stored preceding data block. It is thereby made comparable with the at least one further data block. A soft combining of the received further data block and the transformed preceding data block is then carried out. The payload of the further data block is retrieved from the combined data block.

Abstract: In reduced-stage polar decoding, a received word that is based on an N-bit codeword of a polar code is decoded using fewer than log2N Log Likelihood Ratio (LLR) stages. Decoding uses a reduced stage decoding configuration. In an embodiment, such a configuration includes at least one higher-order LLR stage with nodes implementing functions that are based on a combination of lower-order polar code kernels.

Abstract: A method for the transmission of data via an Inter Communication Link (ICL) to a receiver unit is provided. The method identifies data to be transmitted in a memory cell of a data storage. The method continues by extracting the address of the memory cell and extracting the data word from the identified data. The method continues by calculating a CRC (cyclic redundancy check) checksum from the extracted address of the memory cell and the extracted data word. The method continues by generating a data packet to be sent by appending a start frame delimiter and a stop frame delimiter to the extracted address of the memory cell, the extracted data word and the calculated CRC checksum. The method continues by sending the data packet.

Abstract: A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to transmit or receive an enhanced mobile broadband (eMBB) signal or a massive machine type communication (MMTC) signal that may have its reception overridden by an ultra-reliable low latency communication (URLLC) transmission or have its reception at an evolved node B (eNB) interfered with by an URLLC transmission based on eNB-assisted usage of an outer code.

Abstract: Method, apparatus, and systems for detecting lane errors and removing errant lanes in multi-lane links. Data comprising link packets is split into a plurality of bitstreams and transmitted over respective lanes of a multi-lane link in parallel. The bitstream data is received at multiple receive lanes of a receiver port and processed to reassemble link packets and to calculate a CRC over the data received on each lane. The link packets include a transmitted CRC that is compared to a received CRC to detect link packet errors. Upon detection of a link packet error, per-lane or per transfer group CRC values are stored, and a retry request is issued to retransmit the bad packet. In conjunction with receipt of the retransmitted packet, per-lane or per transfer group CRC values are recalculated over the received data and compared with the stored per-lane or per transfer group CRC values to detect the lane causing the link packet error.
