  • Patent number: 10425858
    Abstract: A method is provided for performing, by a first device, channel coding of data to be transmitted to a second device. The first device determines a size of a transport block for the data, attaches a first cyclic redundancy check (CRC) code to the transport block having the determined size to produce a first CRC-attached transport block, and segments the first CRC-attached transport block into multiple code blocks when a size of the first CRC-attached transport block is larger than a predetermined size. The size of the transport block is determined from among a plurality of predetermined transport block sizes, and the plurality of predetermined transport block sizes are predetermined such that all the multiple code blocks have a same size as each other.

  • Publication number: 20190090260
    Abstract: A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE receives downlink control information including resource allocation information and downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the UE. A resource block pair includes a first resource block associated with a first time slot and a second resource block associated with a second time slot adjacent to the first time slot. The first and second resource blocks are allocated to the same frequency indices. A mapping between VRB pairs and PRB pairs exists such that frequency consecutive VRB pairs are mapped to non-frequency consecutive PRB pairs and that each resource block pair is split so there is a frequency gap between the first and second parts of the resource block pair.
