Claim of US Patent No. 11,071,126


1. A method for use in a wireless transmitter, the method comprising:receiving an indication to schedule a high-priority transmission to preempt a lower-priority transmission, the lower-priority transmission comprising one or more code blocks;
determining a first resource allocation for the high-priority transmission;
determining 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;
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, using the first resource allocation for the high-priority transmission; and
when the fraction of bits in the one or more code blocks of the lower-priority transmission that will be punctured is not less than the threshold, determining a second allocation for the high-priority transmission that minimizes a number of the one or more code blocks that will be punctured and using the second allocation for high-priority transmission.
