Classification: CPC H | IPC H

Claim 7:
8. A method in a second-type communication node used for wireless communications, comprising:
transmitting first information and second information;
monitoring a first radio signal in a first time window; and
receiving a second radio signal when the first radio signal is detected;
wherein the first information is used for determining a target time window, the second radio signal occupies a second time window in time domain, and the second information is used for determining at least one of whether the second time window belongs to the target time window or a relative position relationship between the second time window and the target time window; an end of the first time window is earlier than a start of the target time window, a radio resource occupied by the first radio signal is used for determining at least one of a frequency-domain resource occupied by the second radio signal, a code-domain resource occupied by the second radio signal or a Modulation and Coding Scheme employed by the second radio signal; the first information, the second information, the first radio signal and the second radio signal are all transmitted via an air interface; the first radio signal is generated by a characteristic sequence, and the characteristic sequence is a Zadoff-Chu (ZC) sequence; the first information is cell-specific, the second information is cell-specific; the first time window is a slot with a given subcarrier spacing, the target time window is a slot with a given subcarrier spacing.
