Abstract: Methods, systems, and devices for wireless communications are described. An encoder of a wireless device may receive a transport block (TB) for transmission and segment the transport block into a set of multiple, smaller data segments that respectively correspond to a plurality of code blocks of the TB. The encoder may generate a code block level (CB-level) error detection code (EDC) for a subset of the data segments. The encoder may generate a transport block-level (TB-level) EDC for the TB using the data segments. Each of the code blocks (CBs) may be of the same size and may include one of the data segments. A subset of the CBs may include a data segment from the subset of the data segments and one of the CB-level EDCs. The remaining CBs that are not part of the subset may include a remaining data segments and the TB-level EDC.

Abstract: Embodiments of the present disclosure relate to method and device for data processing in a communication system. For example, a method comprises: generating an error detection code for information bits to be encoded with a polar code, the error detection code being distributed in the information bits in a first order; determining, from among the information bits and the error detection code, a set of bits to be redistributed; redistributing a bit in the set of bits such that the error detection code is distributed in the information bits in a second order; and mapping the redistributed information bits and the error detection code to an input of a polar code encoder to be encoded with the polar code. Embodiments of the present disclosure further provide a communication device capable of implementing the above method.

Abstract: Systems, procedures, and instrumentalities are disclosed for low latency data communications utilizing advanced coding via polar codes. An encoder may receive data traffic that includes different types of traffics such as URLLC data and control information. The encoder may sort the different types of traffics into multiple tiers of varying priorities. The encoder may map data included in the tiers to multiple bit channels of varying channel coding reliabilities. The encoder may receive a bit channel mapping rule indicating that a higher tier corresponds higher channel coding reliability. The encoder may dynamically receive the bit channel mapping rule such that the mapping of priority tiers to bit channels differs from one code block to another code block.
