Determining the MBB UE to puncture to accommodate URLLC traffic

A computer program product embodied on a non-transitory computer-readable medium in which a computer program is stored that, when being executed by a computer, is configured to provide instructions to control or carry out in response to an indication a URLLC traffic needs to be scheduled in the midst of ongoing MBB transmissions in a wireless communications network, determining, from a plurality of MBB UEs with the ongoing MBB transmissions, a set of the plurality scheduled for transmission in a slot required by the URLLC traffic;

• choosing, from the set of MBB UEs, a subset of MBB UEs for puncturing, wherein the choosing of the subset comprises:
• accommodating a reliability constraint of the URLLC traffic, maximizing a sum proportional fairness metric of the plurality of MBB UEs, and minimizing a block error rate in a computation of a proportional fairness metric for each UE of the subset.

An apparatus comprising means, in response to an indication a URLLC traffic needs to be scheduled in the midst of ongoing MBB transmissions in a wireless communications network, means for determining, from a plurality of MBB UEs with the ongoing MBB transmissions, a set of the plurality scheduled for transmission in a slot required by the URLLC traffic;

• means for choosing, from the set of MBB UEs, a subset of MBB UEs for puncturing, wherein the choosing of the subset comprises:
• accommodating a reliability constraint of the URLLC traffic, maximizing a sum proportional fairness metric of the plurality of MBB UEs, and minimizing a block error rate in a computation of a proportional fairness metric for each UE of the subset.
