1. A method of operating a network node, the method comprising:
attempting to obtain a scheduled uplink transmission from a transmitter;
in response to successful decoding at the network node of the scheduled uplink transmission, concluding that the uplink transmission is not skipped by the transmitter;
in response to unsuccessful decoding at the network node of the scheduled uplink transmission and a signal strength measurement for the attempt to obtain the scheduled uplink transmission being below a threshold, concluding that the uplink transmission is skipped by the transmitter; and
in response to unsuccessful decoding at the network node of the scheduled uplink transmission and the signal strength measurement for the attempt to obtain the scheduled uplink transmission exceeding the threshold, performing rescheduling of the uplink transmission wherein performing the rescheduling of the uplink transmission comprises:
attempting to obtain an n:th rescheduled version of the uplink transmission for an n:th rescheduling of the uplink transmission, wherein n≥1; and
in response to unsuccessful decoding at the network node of the n:th rescheduled version of the uplink transmission and a signal strength measurement for the attempt to obtain the n:th rescheduled version of the uplink transmission exceeding the threshold:
checking whether a number n of times that the uplink transmission has been rescheduled has reached a threshold number; and
in response to the threshold number having been reached, concluding that the uplink transmission is not skipped by the transmitter.
