Title: ULTRA RELIABLE LOW LATENCY COMMUNICATIONS (URLLC) TRANSMISSION
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.
