Sub-band configuration for preemption indication to embb ues

A user equipment (UE) for wireless communications, comprising:

• a transceiver;
• a memory;
• and
• a processor communicatively coupled with the transceiver and the memory, the processor and the memory configured to:
• receive an indication channel identifying one or more resources defined by time domain parts and frequency domain parts that have been punctured by an Ultra-Reliable Low latency Communication (URLLC) transmission, wherein a number of frequency domain parts is greater than or equal to two;
• determine a number of resource block groups (RBGs) in an active band width part (BWP) of the UE;
• and
• map the RBGs in the active BWP among each of a number of sub-bands equal to the number of frequency domain parts based on a pre-defined rule.

A user equipment (UE) for wireless communications, comprising:

• means for receiving, at the UE, an indication channel identifying one or more resources defined by time domain parts and frequency domain parts that have been punctured by an Ultra-Reliable Low latency Communication (URLLC) transmission, wherein a number of frequency domain parts is greater than or equal to two;
• means for determining a number of resource block groups (RBGs) in an active band width part (BWP) of the UE;
• and
• means for mapping the RBGs in the active BWP among each of a number of sub-bands equal to the number of frequency domain parts based on a pre-defined rule that defines a mapping of a boundary RBG in the active BWP to one of the number of sub-bands, wherein the pre-defined rule indicates that the boundary RBG is mapped to a sub-band prior to the boundary RBG in the frequency domain.

A computer-readable medium storing computer code executable by a processor for wireless communications, comprising computer executable code for:

• receiving, at a user equipment (UE), an indication channel identifying one or more resources defined by time domain parts and frequency domain parts that have been punctured by an Ultra-Reliable Low latency Communication (URLLC) transmission, wherein a number of frequency domain parts is greater than or equal to two;
• determining a number of resource block groups (RBGs) in an active band width part (BWP) of the UE;
• and
• mapping the RBGs in the active BWP among each of a number of sub-bands equal to the number of frequency domain parts based on a pre-defined rule that defines a mapping of a boundary RBG in the active BWP to one of the number of sub-bands, wherein the pre-defined rule indicates that the boundary RBG is mapped to a sub-band prior to the boundary RBG in the frequency domain.
