Abstract: A method of operating a wireless telecommunications system for communicating higher layer data from network infrastructure comprises establishing an allocation of radio resources for the network infrastructure equipment to use for transmitting higher layer data to the terminal device during a higher layer data transmission period; transmitting an indication of the allocated radio resources to the terminal device; beginning transmission of the higher layer data to the terminal device at the beginning of the higher layer data transmission period; and subsequently identifying during the higher layer data transmission period whether any of the allocated radio resources which have not yet been used are needed by the network infrastructure equipment for transmitting other data in the wireless telecommunications system.

Abstract: A method for encoding data comprises choosing a sequence of pivot candidate positions for a sequence of g encoding vectors to encode a block of g data symbols in a round of coded packets by: providing a set of g pivot candidate positions; choosing a pivot candidate position for the sequence from the set of pivot candidate positions; removing the chosen pivot candidate position from the set of pivot candidate positions; and repeating until the set of pivot candidate positions is empty and the sequence of chosen pivot candidate positions for the round is non-linear. A set of encoding vectors is generated based on the chosen sequence of pivot candidate positions, each encoding vector comprising zero valued coefficients for positions within the encoding vector before the pivot candidate position for the encoding vector and a non-zero valued coefficient for at least the pivot candidate position.

Abstract: This application discloses a code block identification method and related apparatus. The method includes: obtaining a code block stream, where the code block stream includes a first code block; determining a to-be-identified bit pattern and comparing the to-be-identified bit pattern with a template bit pattern to obtain a quantity of inconsistent bits; and identifying the first code block as a first boundary code block when the quantity of inconsistent bits is less than or equal to a first threshold. The to-be-identified bit pattern includes a first bit pattern and corresponds to the first code block. The template bit pattern includes a first template bit pattern and corresponds to the first boundary code block.
