Abstract: Aspects of the disclosure provide a method for polar code puncturing. The method can include receiving a mother polar code including a sequence of coded bits, the sequence of coded bits having indices {0, . . . , N−1} and including at least a first block of coded bits having indices {0, . . . , i−1}, a second block of coded bits having indices {i, . . . , i+k−1}, a third block of coded bits having indices {i+k, . . . , i+k+k−1}, interleaving the second block of coded bits with the third block of coded bits to form a rearranged sequence of coded bits including the N coded bits, and extracting the last M coded bits from the rearranged sequence of coded bits to generate a punctured code having a length of M.

Abstract: A method for URLLC transmission with UE blind detection on scheduling information is proposed. Since increased control channel reliability requires increased physical resource, it is proposed to exploit UE blind detection on part of the URLLC data burst to trade-off control channel reliability with reduced physical radio resource for URLLC transmission. The URLLC burst is encoded to a plurality of low-density parity-check (LDPC) code blocks (CBs), and UE blindly decodes over multiple candidate configurations of the first data CB, and then the non-signaled scheduling information and the first data CB are successfully retrieved passing CRC check, where the CRC of longer size is added to the first data CB. The proposed method leverages UE blind detection and higher layer signaling to carry part of scheduling information to reduce control channel payload, which saves physical radio resource and improves reliability.

Abstract: Concepts and examples pertaining to efficient coding switching and modem resource utilization in wireless communication systems are described. A processor of a modem of a user equipment (UE), configured with at least a first-capacity decoder and at least a second-capacity decoder, receives a common virtual carrier (CVC), a dedicated virtual carrier (DVC), or both. The CVC contains common information shared by multiple UEs, control information for the UE, and/or data information related to first data destined for the UE. The DVC contains control information for the UE, the first data, or a combination thereof. The first-capacity decoder decodes data of a small size up to a low data rate. The second-capacity decoder decodes data of a large size up to a high data rate. The processor determines whether to decode the first data using the first-capacity decoder or the second-capacity decoder based on the data information in the CVC.
