Claim 16:
17. The second-type communication node according to claim 15, wherein the third receiver receives a second radio signal; wherein air-interface resources occupied by the second radio signal are used to determine a first characteristic identity, and the first signaling carries the first characteristic identity; an end time for a transmission of the second radio signal is used to determine start times of the X time windows, and the second radio signal is transmitted through the air interface; the second radio signal is transmitted through a PRACH, the second radio signal is generated by a characteristic sequence, which is either a Zadoff-Chu (ZC) sequence or a pseudo-random sequence; the first characteristic identity is a 16-bit binary non-negative integer, the first characteristic identity is a RA-RNTI; an end time for a transmission of the second radio signal is used to determine a start time of one of the X time windows, a start time of any of the X time windows is a start time of a first OFDM symbol of a Control-resource set (CORESET) of type-1 PDCCH public search space comprised in the time window.
