1. A first communication node for wireless communications, comprising:
a first receiver, receiving first information and second information, the first information and the second information are transmitted as two different fields in a same signaling; and
a first transmitter, transmitting a first radio signal, a Subcarrier Spacing (SCS) of a subcarrier occupied by the first radio signal in frequency domain being equal to a first SCS, the first radio signal carries Msg3;
wherein a sum of a first timing adjustment and a second timing adjustment is used to determine a transmission timing for the first radio signal, and the first timing adjustment is used to determine a transmission timing for a radio signal transmitted earlier than the first radio signal; the second timing adjustment is equal to a sum of a first sub-adjustment and a second sub-adjustment, the first information is used to determine the first sub-adjustment, and the second information is used to determine the second sub-adjustment; the first sub-adjustment is equal to an integral number of Tc, the second sub-adjustment is equal to an integral number of Tc, where Tc=1/(480·103·4096) second; for the first SCS, an absolute value of the first sub-adjustment is equal to a time length of one or multiple multicarrier symbols, the absolute value of the first sub-adjustment is equal to a time length of at least one slot, and a minimum step-size corresponding to the second sub-adjustment is less than a time length of one multicarrier symbol, the minimum step-size corresponding to the second sub-adjustment is a minimum granularity when configuring the second sub-adjustment.
