    Abstract: A station (STA), when operating as a responding STA (RSTA) for time-synchronization of a plurality of initiating STAs (ISTAs) in a time-synchronized network (TSN), may determine, during a negotiation phase, whether each of the ISTAs that intend to participate in one or more measurement phases are requesting to be polled or are requesting not to be polled. For the ISTAs that are requesting to be polled, the RSTA may perform a polling phase prior to performing each of the one or more measurement phases. For the ISTAs that are requesting not to be polled, the RSTA may refrain from performing a polling phase prior to performing each of the one or more measurement phases. The RSTA can directly trigger the measurement phase for ISTAs that are requesting not to be polled. By grouping ISTAs into polling and non-polling groups, efficiency improvements are achieved.
