  • Patent number: 11564237
    Abstract: An exemplary embodiment describes a wireless communication method to selectively operate, based on an inconsistency condition, a transmitting end in one of a first mode and a second mode. When inconsistency is absent, the transmitting end can transmit in the first mode in which the transmitting end schedules transmission resources for interference assessment on a same time unit as data or control transmissions. Upon detection of inconsistency, the transmitting end can transmit in the second mode in which the transmission resources for determining interference are scheduled to occupy different time units than data or control transmissions.
