METHOD AND DEVICE IN A NODE USED FOR WIRELESS COMMUNICATION

WIPO Patent Application WO/2021/180054

A1

The present disclosure provides a method and a device in a node for wireless communications. The first node receives (101A) a first reference-signal-resource set; selects (102A) a first signature feature out of a candidate sequence group in a first period, transmits a first signature sequence on a first time-frequency resource block; when the first signature sequence is associated (103A) with a shared channel resource unit in the first period, monitors a second signal in the second time window; and when the first signature sequence is not associated with any shared channel resource unit in the first period, monitors a second signal in a second time window; measuring at the first reference-signal-resource set is used for determining a first channel quality; 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. The present disclosure ensures access delay demands of 2-step random access procedure.
