According to some embodiments, a method performed by a wireless device for optimizing transmission repetitions comprises: obtaining an initial number of transmission repetitions for coverage enhanced operation; receiving a wireless transmission comprising one or more repetitions; determining a number of received repetitions required for the wireless device to successfully decode the wireless transmission; determining the number of repetitions required to successfully decode the wireless transmission is different than the initial number of transmission repetitions; determining a desired number of repetitions based on the number of repetitions required to successfully decode the wireless transmission; and transmitting an indication of the desired number of repetitions to a network node.

Techniques are disclosed for reducing overhead during hybrid automatic repeat request (HARQ) operations performed by a user equipment (UE) during wireless communication. The UE receives a message over the wireless network and obtains a parity check matrix (PCM) associated with a received message. Rows of the PCM are assigned to respective groups of a plurality of groups, where the respective groups have corresponding one or more parity checks as determined by the PCM. The UE generates a feedback message including a plurality of bits, wherein an individual bit of the plurality of bits indicates whether a corresponding respective group of the plurality of groups include one or more unsatisfied parity checks. The UE then transmits the feedback message to a base station of the wireless network.

A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.

A packet processing method includes generating, by a processor of a network device, a first encoding task based on M original packets in a to-be-processed first data stream, where M is a positive integer, and where the first encoding task instructs to encode the M original packets; and performing, by a target hardware engine of the network device and based on the first encoding task, forward error correction (FEC) encoding on the M original packets to obtain R redundant packets, where R is a positive integer.

Certain aspects of the present disclosure relate to methods and apparatus for optimizing delivery of a transport block (TB) using code rate dependent segmentation.

This disclosure provides a method for determining a communications system parameter, a method for indicating a communications system parameter, and devices thereof. The method for determining a communications system parameter includes: determining a communications system parameter based on obtained first indication information, and/or determining a communications system parameter based on a mapping relationship between an influencing factor of the communications system parameter and the communications system parameter, where the communications system parameter includes a subcarrier spacing of a sidelink channel, and the communications system parameter is used to decode information carried on the sidelink channel.

The present disclosure provides a method for reporting a blind decoding capability, blind decoding configuration, a blind decoding method, a terminal and a base station. The method for reporting a blind decoding capability includes: determining the blind decoding capability information of the terminal, where the blind decoding capability information of the terminal include a maximum number of blind decodings that the terminal is capable to process per time unit; reporting the blind decoding capability information of the terminal to a base station.

Provided is a method of decoding, the method including receiving, by a user equipment (UE), a downlink control information (DCI) that is encoded, identifying, by the UE, a first bit position of the DCI as a known bit, and reducing a number of candidate code words for the DCI based on the known bit.

The application provides method for communicating channel state information (CSI) in a communication network. The method is as follows: An apparatus determines whether a length of CSI is less than a preset length; and adds a padding bit to the CSI when determining that the length of the CSI is less than the preset length, where a length of CSI obtained by adding the padding bit is consistent with the predetermined length. The CSI obtained by adding the padding bit is communicated in the communication network.

Methods and systems that can enable antenna selection (AS) and data bits in transmitted spatially modulated (SM) streams to be detected at a receiver using different detection methods. In example embodiments, encoding for an AS stream is done separately at a transmitter than encoding for data streams, enabling a receiver to use one type of detection for AS bits and a reduced complexity type of MIMO detection for the data bits.
