Claim 17:
18. The first node according to claim 15, wherein
the first receiver detects at least one first-type signal in a first time window;
wherein the second radio resource group comprises at least one first-type time-frequency resource unit, the at least one first-type time-frequency resource unit comprised by the second radio resource group is within the first time window; each of the at least one first-type signal is transmitted, respectively, in one of the at least one first-type time-frequency resource unit comprised by the second radio resource group; a result of detection on the at least one first-type signal is used for determining the target resource pool; the target radio resource is determined autonomously from the target resource pool; a deadline of the first time window is no later than a start time of the target radio resource in time domain; the first time window is orthogonal with the first radio resource group in time domain.
