1. A first node for wireless communications, comprising:
a first receiver, receiving a first reference-signal-resource set;
a first transmitter, selecting a first signature sequence out of a candidate sequence group in a first period, transmitting the first signature sequence on a first time-frequency resource block;
when the first signature sequence is associated with a shared channel resource unit in the first period, the first transmitter transmitting a first signal on the shared channel resource unit in the first period, the first receiver monitoring a second signal in a first time window; and
when the first signature sequence is not associated with any shared channel resource unit in the first period, the first receiver monitoring a second signal in a second time window;
wherein measuring at the first reference-signal-resource set is used for determining a first channel quality;
when the first channel quality is higher than a first threshold, the first channel quality is used for determining the candidate sequence group in the first period;
the candidate sequence group in the first period comprises multiple candidate sequences, and the first signature sequence is a candidate sequence in the candidate sequence group in the first period, a length of the first time window is a first time length, and a length of the second time window is a second time length.
