Abstract
A system and method for blind detection of preempted resources in an orthogonal frequency division multiplexing (OFDM) system is herein disclosed. According to one embodiment, a method for blind detection of resources in an eMBB pre-empted by a URLLC includes receiving soft information including at least one code block, attempting to decode the at least one code block, and running URLLC blind detection on the at least one code block with the decoding attempt fails.
Claims20
A method for blind detection of resources in a wireless communication system, comprising:
- receiving soft information including at least one code block (CB);
- attempting to decode the at least one CB;
- and
- when the attempting to decode fails, running ultra-reliable low latency communication (URLLC) blind detection on the at least one CB.
A wireless communication system, comprising:
- a temporary buffer configured to receive soft information including at least one code block (CB);
- a hybrid automatic repeat request (HARQ) buffer configured to store HARQ information to be combined with the soft information;
- a channel decoder configured to receive the combined soft information and HARQ information and attempt to decode the at least one CB;
- and
- an ultra-reliable low latency communication (URLLC) blind detector configured to detect whether the at least one CB is pre-empted by the URLLC when an attempt to decode the at least one CB by the channel decoder fails.
The system of claim 10, wherein the URLLC blind detector is further configured to utilize time domain (TD) information from the soft information.
An electronic device, comprising:
- a processor;
- and
- a non-transitory computer readable storage medium configured to store instructions that, when executed, cause the processor to:
- receive soft information including at least one code block (CB);
- determine whether enhanced mobile broad band (eMBB) resources are pre-empted by an ultra-reliable low latency communication (URLLC) on the at least one CB by blindly detecting URLLC on the at least one CB;
- and
- decode the at least one CB.
