Claim 0:
1. A method in a first node for wireless communication, comprising:
transmitting a first sequence and a first radio signal, the first sequence being associated with the first radio signal, the first sequence is used for determining a time-frequency resource unit occupied by the first radio signal, the first sequence is used for determining a scrambling sequence of the first radio signal; the first sequence being transmitted on a first random-access channel, and a first bit block being used for generating the first radio signal; the first sequence is a random access preamble; the first random-access channel is a PRACH (Physical Random Access Channel) occasion; the first radio signal is transmitted on a PUSCH (Physical Uplink Shared Channel);
receiving a second radio signal, the second radio signal comprising a first information block; the second radio signal comprises one or more fields of an RRC (Radio Resource Control) IE (Information Element); and
transmitting a second sequence and a third radio signal, the second sequence being associated with the third radio signal, the second sequence is used for determining a time-frequency resource unit occupied by the third radio signal, the second sequence is used for determining a scrambling sequence of the third radio signal; the second sequence being transmitted on a second random-access channel, and the first bit block being used for generating the third radio signal; the second sequence is a random access preamble; the second random-access channel is a PRACH occasion; the third radio signal is transmitted on a PUSCH;
wherein the first radio signal comprises a first identification, the first identification is used for determining the time-frequency resource unit occupied by the first radio signal; the first information block is used for triggering a transmission of the third radio signal; the first information block comprises a first sequence index, the first sequence index corresponds to the first sequence; the first information block is used for determining transmission parameters of the third radio signal.
