Code Block Aware Slot Preemption

Abstract:

According to certain embodiments a method is provided for use in a wireless transmitter that includes receiving an indication to schedule a high-priority transmission to preempt a lower-priority transmission that comprises one or more code blocks. A first resource allocation is determined for the high-priority transmission. A fraction of bits in the one or more code blocks of the lower-priority transmission that will be punctured by the first resource allocation is determined. When the fraction of bits in the one or more code blocks of the lower-priority transmission that will be punctured is less than a threshold, the first resource allocation is used for the high-priority transmission. Otherwise, a second allocation for the high-priority transmission is determined and used to minimize a number of the one or more code blocks that will be punctured.
